TRANSMISSION – More speeds and lower torque

Now that you have added more horsepower – a transmission upgrade kit provides further improvement in performance. This is a modified commercial truck transmission that can handle over 20,000 GVW pounds with better acceleration and lower heat rejection. Remanufactured units with complete dyno testing are even available with a long warranty. The transmission is adapted to fit between the engine and transfer case without moving either and includes new tail housings, new frame cross member, linkages to mate to the existing shift selector and a harness that plugs into the existing vehicle harness, another simple solution.
