B&M Transpak Kits
Transmission Upgrade - Two Kits in One!
B&M's Transpak Kits contain all of the B&M Shift Improver Kit features, and include additional driver manual control for GM TH350/TH400, Ford C6 and Chrysler Torqueflight transmissions. Most conventional automatic transmissions do not downshift into low gear above 15 mph, and they automatically upshift at a predetermined speed, no matter what gear you are in. Installing a Transpak Kit will enable you to downshift at any speed, and you can also hold the transmission in first gear to any desired speed (except Ford C4/AOD, and GM TH2004R/TH700R4/4L60E). This is beneficial when towing a trailer or driving heavy loads downhill. Each kit includes the necessary parts to select either Stage 1 or Stage 2.Stage 1 - Heavy Duty:
For towing, street rods, off-road vehicles, campers, motorhomes, trailers, police, taxi, normal passenger vehicles or other heavy duty use. Firmer shift feel but not harsh. Improves transmission performance and life dramatically without loss of comfort. Full manual downshifts when desired; normal automatic operation when in ''Drive''.
Stage 2: Hi-Performance Street:
For full performance street use. Essentially the same as RV/Heavy Duty mode except shift is much snappier. Retain full automatic features and standard shift points with selector in ''Drive''. Features:
