American Powertrain Transmission Install Tool And Seal Protector

Our trans seal and install tool is a big help for installing and storing your Tremec TKX, TKO and Magnum. We use these to protect the output shaft seal during shipping. The install tool has splines inside so you can use it to help line up your clutch splines during install.
