Transpak - by B&M for Chrysler

The next step up from the Shift Improver Kit is the B&M Transpak for Chrysler. It has all the features in the Shift Improver Kit plus it provides additional driver manual control (GM TH-400, 350, Ford C-6 & Chrysler Torqueflite only). Most stock automatic transmissions won't downshift into low gear above 15 mph, and automatically upshift at a predetermined speed no matter what gear you're in. With the Transpak, you can downshift at any speed, and you can hold the transmission in first gear to any speed that you want! This is an asset when you've got a modified engine, and you want additional RPMs, or you're towing a trailer or driving heavy loads downhill.

Stage 1 Heavy Duty - For street rods, normal passenger vehicles or other heavy duty use. Firmer shift feel but not harsh. Improves transmission performance and life dramatically without loss of comfort. Normal automatic operation when in "Drive".

Stage 2 Hi-Performance Street - For full performance street use. Essentially the same as Heavy Duty mode except shift is much snappier. Retain full automatic features and standard shift points with selector in "Drive".

  • Recalibrate your automatic transmission for optimum performance.
  • Select the mode that best suits your application.
  • Improves transmission life.
  • Transmission removal not required.
