American Powertrain Pro-Fit TKK 5-Speed Systems

The TKX Pro-Fit fits vintage Charger, Coronet, GTX, Road Runner, Satellite, Belvedere, Super Bird and Super Bees like an original A833 manual transmission with the correct shift position and tunnel fit.

American Powertrain has introduced its new Pro-Fit 5-speed system for classic Mopar B-body cars featuring the all-new TREMEC TKX 5-Speed. The TKX Pro-Fit fits vintage Charger, Coronet, GTX, Road Runner, Satellite, Belvedere, Super Bird and Super Bees like an original A833 manual transmission with the correct shift position and tunnel fit. The new TKX features a streamlined case for zero tunnel modifications. American Powertrain modifies the TKX to mimic the stock 4-speed shifter location. Replica pistol grip shifter handles and shift pattern plates finish out the look for factory original. 

The new Pro-Fit 5-speed system features the new TREMEC TKX transmission with 600 lb.-ft. of torque capacity with shifts up to 8,000 rpm. The system comes with American Powertrain’s patented driveshaft yoke, bolt in crossmember that works with the factory torsion bar mount and brand new DOM driveshaft. The Pro-Fit kits are covered by American Powertrain’s two year warranty and comprehensive tech support, and will be available for shipping in early Spring.

American Powertrain, a TREMEC Elite Distributor located in Cookeville, TN,  manufactures and sells Pro-Fit modern overdrive transmission systems, Hydramax hydraulic clutch systems, X-Factor Cross Members and thousands of powertrain accessories for muscle, sports, street rod and race cars.
