B&M Transpak™
- Recalibrate your automatic transmission for better performance.
- Select the mode that best suits your application at installation.
- Improves transmission life.
The next step beyond the Shift Improver Kit. The Transpak has all the features in the Shift Improver Kit plus
it provides additional driver manual control. Most conventional automatic transmissions won’t downshift into
low gear above 15 mph, and automatically upshift at a predetermined speed no matter what gear you are in.
With a Transpak you can downshift at any speed (except C-4, AOD, TH-200-4R and TH-700-R4), you can
also hold the transmission in first gear to any speed that you want. Downshifting at any speed is an asset
when towing a trailer or driving heavy loads down hill.
Stage 1. RV/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.
A real neck snapping, instant shift. Retain full automatic features and standard shift points with selector in "Drive".
Stage 3. Full Competition
(except TH-700-R4, 200-4R & AOD)
For racing applications. Features a full competition shift and higher shift points. Extremely hard shifts and
higher shift points make this mode unsuitable for street use. Maintains automatic shift feature. For full manual
control, see a ManualPak
