Ford F-150 1977-1978, Transpak Shift Improver Kit by B&M®. Includes: Gaskets, Drill Bits, Seals, Retaining Ring, Brass Plug, and Shift Valve. 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 you want! A TransPak will allow you the control to do everything from rev-out a modified engine for maximum performance, to hold a tow vehicle in low gear while descending a grade.

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 quicker. Retain full automatic features and standard shift points with selector in "Drive".
