Specification
Description
The B&M Shift Improver Kit is designed for 1996-1999 Ford, Lincoln, and Mercury vehicles equipped with the 4R70W automatic transmission. This kit recalibrates your transmission for optimal performance and extended life, providing two selectable modes: - **Heavy Duty**: Delivers firm, positive shifts without compromising driver comfort, ideal for regular street driving and towing applications. - **Street/Strip**: Offers very positive shifts suitable for high-performance street use or competitive events, providing the hardest, quickest possible shifts. Installation is straightforward, requiring only basic hand tools, and can be completed in an afternoon. The kit includes all necessary components such as gaskets, seals, a drill bit, and fluid separators. By eliminating soft and sluggish shifts, shift overlap, and excess wear on clutches and bands due to slippage, this kit enhances transmission life and performance.
