The B&M Transpak is the next step up from the B&M Shift Improver kit.

The B&M Transpak kit for 1980-1992 Ford, Lincoln, Mercury AOD automatic transmissions (excludes 1992 and later with electronic shift). Most stock automatic transmissions wont downshift into low gear above 15 mph, and automatically upshift at a predetermined speed no matter what gear youre 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 youre towing a trailer or driving heavy loads downhill. Stage 1.
