The New TREMEC TKX is the new 5-speed in town. TREMEC has normally sourced their aftermarket transmissions from the OE side, such as the Magnum T-56 and the T-5. This brand new design is made from the ground up as a strictly aftermarket transmission. Designed to fit classic muscle cars and customs, the TKX has a tighter, more streamlined case.
TKX 5-Speed Manual Transmission Features and Benefits
- The TKX has 600 lb.-ft. of torque capacity and is capable of engines speeds of 8,000 RPMs with shifts at 7,500 RPMs. It is available in multiple gear ratio configurations (See chart below).
- Designed for multiple applications with three shifter locations. Compact, end-loaded design provides clearance in most transmission tunnels without floor modifications.
- Increased case strength with three-piece aluminum housing provides outstanding structural stiffness (includes main case, intermediate plate and rear extension). Gaskets at all flanges simplifies installation and eliminates fluid leaks.
- Superior shift-ability through use of multi-cone synchronizers and hybrid synchronizer rings made of sintered bronze and carbon
- Noise, vibration and harshness (NVH) minimized with gear layout to best control stress levels. All gears supported by caged needle bearings to reduce end play on the gears.
- All gears and shafts made from special grade steel (ASTM 4615) providing increased torque carrying capacity.
- Equipped with a high-performance short-throw billet aluminum shifter that isolates road noise, while providing clean, crisp shifts.
- Robust design with internal three-rail shift system and steel shift forks.
- Wide gear width increases gear life and torque capacity.
- 26-spline input shaft with a 31-spline output shaft for added strength.
- Built-in reverse light switch and cruise control safety switch.
- Separate GM and Ford case patterns and input configurations. Integrated GM and Ford transmission mount patterns.
American Powertrain can also provide a mid-shift conversion, as well as a White Lightning shifter. The White Lightning Shifter features over 60 additional shifter locations to help get the new TKX set up for your muscle car, truck or custom project. American Powertrain will also have a direct fit version for Classic Corvettes and Mopars, which feature a 12-month/12,000-mile warranty backed up even further with American Powertrain’s two year warranty. Check out the images below and the new TKX Gear Ratio Chart….

Corvette C1 C2 and C3 version coming soon!
ok looking to see if this will work with a factory 4 spd A body Mopar. 1968 Dodge Dart.
Yep. You have to use this trans with our Mopar A body kit. We have been doing those for years with TKO. Just give us a call.
Without floor modifications?
Honestly we do not really know yet as we have not had time to fit the TKX to all the applications since TREMEC just came out with it. TKO you have to cut the floor for sure. TKX is smaller but A-body mopar has a really small tunnel. So to be safe I can’t tell you yet you wont have to modify the floor until we get all our engineering done.
Will this work with 2018 L83?
Sure will. Just need a bell and flywheel combo. Just call us at 93-646-4836
I have a ’69 corvette. Do you have a TKX kit like the TKO SKU: PFGM-20007 kit?
We have the TKO kits now for Vettes. The TKX kits will be ready after 1st of the year.
does it have a shifter to fit factory consoles? (64 GTO ?)……. and how much more $ is the shifter?
We have all that. Just call us for a quote on an A-body conversion kit. TKO kits have been around for years. The TKX is the same except it fits the floor better. You need to have the right offset shifter for the transmission which we make just for the console cars.
I have a 64 Chevelle SS 4 speed car, will the TKX fit in my car?
Sure will! We have a complete turn key kit for A-bodies.
I have a 1978 chevrolet malibu with a 454 bored and camed , behind is a four speed with 3:73 gears. Would your TREMEC TKX adapt to my malibu?
They adapt to any Muncie bolt pattern. Bolts up just like a TKO did before. We do Chevys in our sleep. Just give us a call.
So will this GM 5spd bolt up to me ..621 bell housing?
Yes
Im doing a different engine swap and was looking to see if you offer kits for different motors? Its a 2.8l vr6 out of a vw.
nope
That sounds cool and all. But I would like to have one specifically made for the 4.3L V6 Chevy engine. Because it would be nice for us gearheads who like muscle but don’t like the fuel economy of the V8 engines.
It does sound cool…..You know the 4.3 has a small block chevy bolt pattern right? the TKX bolts up to any SBC bell housing…We have all the stuff you need to make it work.
Will this be a direct fit with no modifications for a 69 camaro .Do i need a different crossmember .What else do i need thanks
Yep…You need our TKX Pro-Fit kit for 1st Gen Camaros. Give us a call at 931-646-4836. We do our quotes over the phone per application since there are many options.
I’m interested the TKX in close ratio with .81 for my 65 Fastback Mustang in 10 spline input is that possible? Also how much work will need to be done if any to the Transmission Tunnel to fit?
Yes we have that and no mods. You can even fit a 6-speed in a 65. Been doing these for years. TKX makes it even easier…
Wondering if this will fit in an early model 1965/66 mustang without having to modify the floor pans? Thanks!
Yep you can even fit a 6-speed in a 65/66 been doing them for years…
Will this fit in a 1965-66 Mustang without modifications?
Thanks!
Yes its super easy..
Sounds real good, but I got one for you. Do you have a version that will fit in a 1973 pinto four cylinder 2.0 liter?
Easy
I have a 73 Trans Am will it fit my bird without tunnel modifications ?
Yes
Same input spline as a Muncie? I can use my old clutch disc on my small block Chevy V8? How about the transmission yoke same number of teeth? How about the length of the transmission is it the same?
No its 26-spline. Its longer and you have to have a new driveshaft made. 31 spline yoke. It bolts up like a muncie. We have been doing the kits for years with the TKO for munice cars. We make the drive shaft and supply the correct crossmember and all that. Just give us a call.
When can you send a TKX for a corvette 68 to Norway?
Corvette kits are still in TKO form right now till end of January. After than we will switch over to TKX.
Got an 84 foxbody, will the stock drive shaft work with this conversion? Im currently setup with the t-5
Sure won’t. TXK is longer than a T-5 and requires a 31-spline yoke
I have a 1963 Ford Galaxie with a 429 installed. I want to switch from AT to manual and have been looking at the TKO, so this is good news.
Do you offer a bellhousing, flywheel, release bearing, the new TKX with a shifter location close to the stock one.?
I have a full machine and fab shop on site, so a crossmember and motor mount position are flexible. I just need the shifter to fall somewhat close to the factory location. Will be using a set of stock car race pedals and master cylinders.
We have everything you need for that car but a crossmember but we have adjustable universal ones that will work.
Have a 1970 442 with a Muncie 4spd and console, will install require any tunnel modification.
Thank you
With the TKX it will not. Give us a call for a quote.
Looking for a tkx kit for a 1966 chevy II. The car currently has a 283 v8 with a muncie 4spd. The car has a bench seat and 3:08 rear gears. I am considering changing the rear gears to 3:73 with the tkx 5spd.
Give us a call for a quote 931-646-4836
Would this fit in a 71 Lemans sport which originally had a th350? Or would tunnel mods still be required?
It will fit we have a kit
considering a big block in a dodge d-100 pu
do you have a kit or bellhousing, etc?
We can get most of what you need for D100. Bell housing is easy we have all mopar bells. Give us a call
It appears the txk will handle 454 BBC torque easier than previous model’s. Would like to install into a 2007 Chevy Silverado classic. Thoughts?
Call us for more info and a quote we can get you close but you are on your own for a crossmember.
Does a TKO 600 shifter fit theTKX?
Sure doesn’t. TKX is a new design
Do you already have the mid-shifter kits worked out? Also, do these have the improved synchro and shifter rail systems more like a magnum than a TKO? There is definitely a difference in how a Magnum feels versus a TKO.
Mid Shifter will be ready by first of the year.
I have a 1965 Chevy impala 396/four-speed, what transmission will fit without modifying the floor and will fit the stock console.
TKX will fit but there still might be some trimming. Those tunnels are tight.
i have a 1976 pontiac trans am 455 and a borgwarner 4speed . do you have a tkx kit for my car? the car has orginal consol and i dont like to cut in the floor is it possible with the new tkx? when is this kit ready for shipment and what is the part/order number for this kit?
We have a kit. Give us a call at 931-646-4836 so we can go over the details.
Will my Mcleod shifter from My TKO600 fit the new trans?
sorry it will not.
I have a 1993 Ford F150 Lightning, automatic 351windsor, 410 rear end. Would like to convert to manual and looking to free up final ratio for more cruising ability. Thoughts?
.68 overdrive is the best one. Use our speed analyzer here. https://americanpowertrain.com/speed-analyzer/
TKX is not listed in it yet but its pretty much the same as TKO
Will a shifter from a TKO600 fit it?
Sorry no they are different
Can you guys explain how you fit a T 56 in a 1965 Mustang without tunnel mods and keeping the correct driveline angle thanks?
The Magnum is rounded on top so it fits the Mustang tunnel better than a TKO. and our crossmember helps put it in the right position.
Does the TKX have a safety clutch, Or a neutral light hook up as does the TKO 600, I can’t tell by the pictures
Yes it has a neutral safety switch and reverse light.
Hello – I have a 77 Olds 442 that I converted to a 4 speed. I have a 73 442
4 speed console in her, will the TKX shifter be in the same place or will I need to cut the floor?
Thanks Matt
Yes we can mimic the stock shifter location. The TKX will fit A-bodies without cutting.
I have a 1967 C10 steptside short bed and the engine sits very close to the firewall. The engine is a 350 with 3.42 rear gear and a B/W super T10 4speed bench seat.Question: will your TKX fit without cutting the tunnel and would the shifter have to be moved to mid-position, and does it cost more to move the shifter?
Yes you have to cut the tunnel but we have C10 factory style tunnel humps. I had a C10 and you dont have to run a midshift for bench seat.
I just ordered the American Powertrain Tremec
TKX transmission from Summit Racing! It says ship date is Jan. 18th, 2021. But I see you guys say you will start shipping on Nov. 30th, 2020. Should I expect my unit to show up in December 2020?
We honestly do not know yet. Tremec is keeping us updated.
What modifications would have to be made to install a TKX in a 1957 Chevy that has a Muncie in it now?
None. Just give us a call at 931-644-4836 for quote
What shifter position to you recommend for a 1964 Ford Fairlane with a bench seat? Thanks
We put the stock Fairlane 4-speed position on the trans for you if you order a Fairlane kit from us.
I have a 1968 Camaro with an LS376 engine and stage 2 cam. I am looking to buy an engine and saw that the TKX might look a bit fit yet especially since it resembles in the most part the TKO 600/500 transmission, has the same torque capacity (600ft-lb), and has an 8,000 rpm max.. Would there be a kit available for this configuration? And if so what would be the pricing for a close-ratio kit that would have everything needed to just drop it in. Thank you!
Jim
TKX and TKO are the same for any of our old kits. The TKX just replaces the TKO with a better case and better shifting. The best thing to do is fill out our RFQ link on the site or call us at 931-646-4836. We like to quote the kits since they have tons of options.
Looking at this for a 69 AMC AMX 390 currently with BW T10 … Is this possible …
Yes we can do it. We do not have a crossmember but we can bolt it up to the AMC engine.
Will this work in a Chevy 67 c10 , want to use original truck bell housing and clutch fork , rear cross member is a th350 that I have , I can have drive shaft done locally, I will need A yoke? Rear gears are 4:11, what OD Would be better.
Yes it works we have complete C10 kits. You will need to cut the floor or get one of our C10 tunnel humps with your kit. It does come with a yoke. But keep in mind our Pro-Fit kits come with a new driveshaft. Just call us at 931-646-4836 for a quote.
Will this be made for a Supra/SC300? Or can it be configured or possibly thought about for the future?
You can bolt one in to a Supra using this bellhousing from Quicktime. You will need to fabricate a crossmember and build a new driveshaft however.
https://www.holley.com/products/drivetrain/bellhousings/toyota/parts/RM-4031
Looking for a belhousing to mate the newer duratec- mazda-ford 2.5 with a ford spec of the tkx.. The mustang ecoboost 6speed bolts right up too the 2.5… But I don’t want to go thru the hassle of that swap as the tkx is much stronger.
Not sure on the 2.5 since nobody has asked about it. Holley makes a few bellhousings for ECOBoost for V6 and 2.3.https://www.holley.com/products/drivetrain/bellhousings/ford/parts/RM-8090
We have done some applications for the 2.3 but you will need a very expensive flywheel to make it work. Centerforce makes them.
I am building a 445 FE Ford putting together a street/strip 68 F100 short bed. Can we use this TKX. I have the TKO600 in a 91 fox and love it. My concern is shifter placement.
We do F100s all the time. They fit the same at the TKO as far as shifter placement. We have several options. Just give us a call at 931-646-4836
Will the TKX work without any tunnel cutting or oddball shift lever orientations in a 2008 Mustang GT? Is it compatible with the S197’s input shaft-mounted throwout bearing and are there any known spacer requirements? I’m looking at the TKX as a possible alternative to the Magnum XL, for use at HPDE track days where at least 3rd, 4th, and 5th are closely spaced, with 5th gear being around 0.8. It looks like gearing in the TKX would be slightly better around town than a 2.66-low Magnum, and not quite as good for long highway stretches.
It will fit but you are taking long way around to get gear ratios you want. We can change gear ratios on a Magnum XL which will fit 1000 times better in that car. Give us a call at 931-646-4836
Is trans crossmember mount in Same place as a Muncie / Borg Warner trans?
For what car? For the most applications our mounts bolt in the stock location.
77 Chevy nova
Howdy!
How well will the TKX fit in a third generation camaro/firebird? Is anything special required?
We can fit 6-speeds in them just fine. TKX will fit.
They took out the torque arm provision . I watched a video where they said they where going to work out some kit that the torque arm would probably be attached to the crossmember i think . Im also waiting to hear more about this . I cant wait for this trans . I have a 3rd gen Fbody as well
Our 3rd Gen will have the torque arm mount on the cross member like before. We never used it on the TKO most companies didnt either. So its not a loss.
I bought a frame from tci for a 36 ford it was built for a gm 4 speed. Can I convert it to your new 5 speed with out modify the frame?
That’s a question for TCI. You need to ask them if the crossmember on the frame is adjustable for a TKO/TKX. They are longer than a Muncie.
Thanks, Matt. Either way, it’s a long-lead kind of thing and I’m mostly looking to see if there are any hard deal-breakers with respect to the TKX. To date, the Magnum XL has been the leading choice, but then the TRX showed up as an alternative at least worth looking into.
I have today a 65 Mustang with a 5.0 and a t-5 trans
what do I need to put a TKX in the car?
Rolf Johnsson Sweden.
You will need to swap the bellhousing, crossmember and shorter driveshaft. We have all that.
I have a ’61 Falcon with a 408w and a t-5. What am I looking at to swap this in? I’m already drooling at the thought of not having to worry about grenading my tranny if I unexpectedly find to much traction.
There is a lot to cover on this and the best thing to do is call us at 931-646-4836.
Will they fit the Mopar e body without cutting the tunnel etc ?
We have an E-body kit in R&D right now. It will be done mid Jan. You will not have to cut the floor. But a stock TKX out of the box will not work. You will need our kit.
Which TKX is compatible with my 1966 Mercury Comet Cyclone 390 GT? What bellhousing do I use? Will the stock crossmember work with TKX? What effect will TKX have on diveline pitch to rear axle housing? Will TKX shifter fit stock cut out in center tunnel?
We can do all that we have the stuff you need. But give us a call at 931-646-4836 so we can go over all the details and get you quick quote. 931-646-4836
What is the size (dia) of the bearing retainer on the front of the transmission, want to mate it to old truck bell housing in a 67 c10 1/2 ton in place of truck 4sp,
We strongly suggest getting a new bell. Those old C10 bells with the motor mounts are sketchy at best for proper bell alignment on a modern transmission. We have gone down this road a lot with customers on those. Any muncie style new bell will work. We also sell them.
Is there a configuration to fit one of these in 66 Chevelle SS 396 with factory 4 speed console?
Yes just call us at 931-646-4836 for a quote
I have a 39 Chevy coupe with an LS3 7004R combo now with no floor pan mods.
Do you think the TKX will fit in the same basic location? I am not opposed to some mods but would rather not have to if possible. Also do you offer an install kit like some others? (bell, clutch, flywheel, ECT,,,)
Hello,
I would like to know will this new TKX box bolt straight up to a Cleveland engine standard bell housing pattern or is there sum mods I would have to do, I have a 1970 falcon.
Regards,
Dean.
Ford versions of TKX are just like TKO they have a toploader bolt pattern. We also have brand new small block bells with the correct bolt pattern.
Any fitment for auto to manual LS swap 69 Chevelle? Hack the floor or easy fit?
Of course we got those kits. You don’t have to cut. Right now however we are looking at late January before we have stock on TKX.
Do you have a kit for a 57 ford ?
Any dealers close to iowa?
https://americanpowertrain.com/dealer-locator/ check out our dealer locator here or call us at 931-646-4836
Do you have a setup for a 1996 GMC 1500 4×4 with the 5.7L?
Sure don’t. We only do 2wd
Do you have the extreme upgrade for the TKX yet?
Once we get some inventory next month we will.
Do you make a GM 6 speed conversion for the full size V8 pickup truck?
What truck and what year??
I see tremec is close until January 4th by there web site. Do you have a realistic time when they
Will begin shipping the tkx? I already have a order with americanpowertrain.
I wish we did. We have over 100s of units on order so we are waiting on a shipping notification from them. Currently we think its going to be mid Jan or end of next week before the first batch gets here. A lot depends on when you placed your order.
Number 78 on your list
December 14, 2020
I can’t believe I’m the first to ask this but Will the TKX fit in a SN-95 Mustang 5.0?
You are the first to ask this on this post. But yes it will fit. Its just like the TKO but smaller case.
I have a 55 Ford custom line I was wondering if the new TKOX will go in without hump modifications on this it has a 410 FE motor in it was a four-speed now
We have not fit them to any 55 Fords yet. it will fit better than a TKO would. We can bolt them up to FE engines however.
Hi. Will it fit 67 GTO without floor modifications?
Sure will
I currently have a t-5 swapped in to my 1965 mustang that is pretty overpowered by my new motor. What modifications would be needed to swap in the TKX?
Crossmember, bell and driveshaft. Give us a call at 931-646-4836 we can go over it for you.
Hi will TKX fit for 63 Impala orginal 4 speed car with floor console, do you have shift kit for it ? Going for Ls swap .
We have a TKX kit for the impala just give us a call at 931-646-4836.
Does this use the same bolt pattern the TKO uses for a GM? So If I had a TKO600 already and wanted to switch to this I wouldn’t have to change the bellhousing?
It’s exactly the same bolt in and mount.
1970 Chevy nova ss396 factory four speed , no console car . I like the TKX as an option , wondering about the floor and any cutting or trimming , the car is an original 396-375 , I don’t want to cut up the floor . Also can a factory clutch set up work ? I have a m-22 now with 1350 u joints , any info would be appreciated , thanks
It will fit with no cutting. you can reuse all the factory linkage, crossmember and bell housing. You will need a 26 spline clutch and a new driveshaft since its a longer trans and has a much larger yoke 31-spline. We have all that. We do A-bodies in our sleep.
Thanks Matt , so if I get the trans mission n shifter , do I need a different crossmember ? And how about a ruffcost on the conversion ? Thanks again
Never mind about the crossmember Matt ! Slow reader here ! Sorry
Do you have a shifter for the TKX for a 1970 Camaro factory console?
We set up all our transmission kits to fit like factory with consoles and without consoles.
Has there been any verification on fitment of the tkx in a Mopar a body with or without floor modifications. Also, I placed my order in late November. Any updates on when orders will be fulfilled?
We still have not verified fitment on Mopar A-body. We are finishing up B and E body right now. We have a lot going on in R&D just trying to get to all these designs. A-bodies are so tight on the floor it’s going to be close. Tremec is telling us now Ford TKXs will be shipping in March. They are building GM units first those are rolling out in Feb. Sorry for the delay. Since you ordered in Nov you will be one of the first in March to get a Ford unit.
I have a 1984 Mustang SVO with the 2.3 turbo four and a T5. Is there a kit for the TRX to bolt up to the 2.3?
We can make it work. Just give us a call at 931-646-4836. You do need a different bellhousing and driveshaft.
I have a Buick 215 that is presently mated to a GM T5. It is modded for a neutral safety switch and an electronic speedo output. Does the TKX come standard with a neutral safety switch? What is the output of the electronic speedo output (pulses per mile?)? I noticed that the rear transmission mount is straight not tilted as I now have. Is this the same distance to the rear from the front mount face as the T5? I presently have my shifter located 2 inches to the rear and 1.5 inches to the left (drivers side). I think that your shifter position is 1 inch further to the rear than the T5–am I correct? If not is the shifter position in the same location as the T5? Thank you for any help.
GM T-5 speedo output is different that TKX. They all use the Ford output signal. You will need dakota digital converter to make it work. They all have the neutral safety switch. You will need a TKO/TKX bellhousing. That tilted T-5 one will not work. we can match the shift location using our offset shifter set up. Just give us a call at 931-646-4836.
any updates on the TKX fitting a mopar a body ? going to rebuild the hemi 4 speed behind my hemi but this might be a better avenue to look at . will this unit take lots of torque ? thx Ron
600 lb.ft of torque more if you are just running street tires. A-body kit will be out late spring. It will still require tunnel mods to fit.
Hi, I have a 65 mustang, 363cid (Boss302) with a Quicktime bellhousing RM-6065 (for TKO 500/600-TR3550-T5, depth 6.925″) and currently a GForce T5. Do I need to swap the bellhousing for the TKX or will i fit straight on?
Also what is the input shaft bearing retainer outside diameter (for the hydraulic release bearing)? Thanks, Jan.
T-5 and TKO Ford all the hydraulic bearing size is the same.
Hi, I have a Quicktime bellhousing RM6065 (for T5, TKO 500/600, TR3550) on my Ford 302, will this transmission fit this housing without any adapters or modifications? Also, what is the outer diameter of the input shaft bearing retainer (for the release bearing)?
Any bellhousing made to use with a TKO will fit TKX as well.
In the process of installing one of your TKO-600’s in my 65 Corvette behind a 427 LS-3 and having issues with tunnel clearance on top to achieve the necessary driveline angles.
I need to raise the tailshaft and just questioning if the new TKX provides more room on top before proceeding with tunnel modifications.
Thank you
The TKX will provide more room. However our TKO kits fit those cars with no mods much at all. Is this a modern LS engine? If so you have to be careful what motor mounts you use. They can raise the crank centerline different from stock.
Thanks Matt.
It is a custom build late gen LS. The motor mounts are sliders by Dirty Dingo which actually sit the motor down pretty low.
Going to install the Corvette floor sag kit provided by SST which should raise the tunnel some.
Hello
Just purchased a 2001 ls1 corvette engine to go into my 96 2.2l s10. Will your new tkx box fit and do you sell the parts required to bolt it up to the ls1. The s10 has a rather large tunnel so room should not be an issue. Thank you.
Allan
We have everything you need to do that except a crossmember for the S-10 everything else is easy.
Hello,
Restoring a 68 Chevelle. Plan to put SBC Blueprint 383 in and would like the TKX 5 speed behind it. It will have bench seat and has original tunnel(orig trans powerglide). Will I need tunnel mods and does the shifter position work with bench seat?
Thank you,
Darren
You do not need to mod the tunnel for a TXK. We have full kits for A-bodies for factory shifter locations bench or buckets. Just give us a call at 931-646-4836
I purchased a TKX 17805 for my 69 Camaro. I have a 3:31 rear and 26.5in rear tires. What would you consider an optimum rear ratio for my car?
I have a 65 Galaxie with a 351 Windsor, auto trans w/console. Will the TKX work, my end goal, dependable street car, daily driver at 400-450 hp? Oh, nice fuel mailage would not hurt either.
What are the bolt pattern measurements for the Ford style 10 spline wide-ration TKX? What is the length and diameter of the input shaft for the 10 spline wide-ratio Ford style? My application will be for a 1963 Studebaker Avanti with stock 289 engine and factory BW T-10 wide ratio 10 spline trans with Ford bolt pattern. thanks
if you have a T-10 it will bolt in. Same bolt pattern same splines everything if you use a 10 spline Ford TKX.
Any lower profile shifter housing with offset for second generation Camaro?
Yes we have all that for each muscle car application for TKX.
When are these shipping? It says November 30th 2020 but it’s March now.

I have a 76 TA with a modified 455 (400 RWHP) with a 3.23 rear end, originally equipped with Super T10. Which transmission would you recommend and with which gear ratios?
We recommend a TKX 17805 with the .68 gear. If you really want to get the gearing just right we suggest going with 3.73 gears as well. This will give you a great powerband throughout the gears and make overdrive a ton more useful.
I have a 68 Chevelle 396 with a Muncie 4 speed, and would like to install the Tremec TKX, do they bolt to existing bell housing like the Muncie or are there special alignments and critical tolerances and proper driveshaft angles to be concerned with.
Bolts right up. But you need to do a bellhousing alignment procedure. Driveshaft will also need to be upgradeded as it is shorter for the TKX and needs 31-spline yoke. If you order an A-body kit from us all that comes with it.
I’m doing a hellcat swap on a ‘69 Charger. It doesn’t look like the TKX has quite enough torque capacity. Will there be a pumped up version of this or am I stuck with the 6060?
You need a Magnum. It can handle the Hellcat. We sell them every week for Hellcat swaps. We can also upgrade them to 1100 lb/ft of torque.
Any update on the TCET17722 Road race GM
All we know from Tremec right now is end of April or early May…
Would appreciate price and availability of the TKX forward shifter conversion kit. Also, does the neutral safety switch work with this kit ? Thank you
Neutral safety works just like the TKO did. How far forward are you needing it? The stock TKX shifter will flip forward 3″ If you need it more we have our WL shifter than can add up to 3″ more offset. You can select how long the offset needs to be on the product page. if you need it to be mid-shifted in the center of the trans that will be available by summer. But if this one works check it out.

I have already purchased a new TKX 17765 locally. I am putting this in a ’66 Fairlane 427 FE (484 stroker). Does Tremec or American Powertrain have a solution for the short FE style input shaft? Thank you!
Tremec does not. Give us a call we have a fix for it. 931-646-4836.
Will there be a modern hemi 5.7/6.1/6.4 kit
We have been bolting TKOs to them since the start. TKX bolts up just the same. We have everything you need. Just give us a call at 931-646-4836.
We are building a 67 Fairlane and we are thinking of using the TKX, we are going to be running 390 FE, will this trans bolt up to the stock bell housing or will we need an aftermarket bell housing. Also what hydraulic clutch do you recommend for this setup
There a few things we have to do for FEs since their bellhousing depth can be an issue. We have our own Hydramax hydraulic kit we offer. Give a us a call at 931-646-4836. Its too much to cover via typing. But we do FE all the time.
Do you know if a tkx will fit in an 85 Monte Carlo without tunnel modifications?
G-bodies have small tunnels. We have not had a chance to fit one yet but we know you have to put a full tunnel in for a TKO. The TKX will fit better but it’s probably going to need some tunnel trimming.
