The B&M® Transpak represents the advanced evolution beyond the B&M Shift Improver kit, encompassing all its features and introducing additional manual control for specific transmissions (GM TH-400, 350, Ford C-6, and Chrysler Torqueflite). Tailored for 1970-1982 Ford, Lincoln, Mercury C4 automatic transmissions, the B&M Transpak™ fine-tunes your C4 transmission for optimal performance to meet your requirements. In contrast to stock automatic transmissions that limit downshifting into low gear above 15 mph and impose predetermined upshifting speeds, the Transpak empowers you to downshift at any speed and retain first gear to your desired speed. This flexibility proves valuable for modified engines, towing trailers, or navigating downhill with heavy loads.
Key Features:
- Recalibrates your C4 Automatic Transmission
- Full Manual Control on Most Transmissions
- Improves Transmission Life
- Optimum Performance
- Firmer Shifts
Note: Stage 1 (Heavy Duty) is suitable for street rods, regular passenger vehicles, and other heavy-duty applications, offering a firmer shift feel without harshness. It dramatically enhances transmission performance and lifespan without compromising comfort during normal automatic operation in Drive. Stage 2 is designed for dual-purpose performance vehicles, Hi-Performance Street/Strip, Off-Road/desert, and 4-wheel drive use. Stage 3 is exclusively for competition use and not recommended for street applications.
