This crossmember will fit 1996 and later 4L60E, and 4L65E transmissions for LS engine swaps.
The RCB3-700 is designed for the 700R4 / 4l60E transmission with a case mount transmission mount. For a 700R4 with a tailshaft mount purchase the RCB3-400 crossmember instead.
Engineered with 2 mounting slots to accept a standard height transmission mount.
We recommend a polyurethane transmission mount. The GMTM is sold separately.
