    Clean, Chirping Shifts. This shift improvement kit from B&M will improve the shifting efficiency of your Mustang, giving it the ability to perform tire-chirping shifts with little to no effort. By improving the performance of the shift itself, the lifespan of the engine is also improved, as is its sound.

    A Breath of Life. B&M's shift improver increases the life of your transmission by speeding up the actuation of the shifting motion. Solid construction ensures the kit can resist wear and tear, as well as other forms of corrosion like rust. This upgrade is ideal for street and strip. After installation, users can expect the upgrade to last for years with little to no maintenance.

    No Trip to the Mechanic Needed. The shift improver is easy to install and does not require the removal of your vehicle's transmission to complete the upgrade. Everything can be done in an afternoon, and requires only basic hand tools. The package ships with all other hardware necessary to complete the job.

    Application. This BMR Shift Improver Kit is designed for 1996-1999 GT and V6 Mustangs with 4R70W transmissions.

    Can the shift improver kit be used on a mustang that already have a sct/x4 Bama tuned programmed on it.


    • They can be used at the same time, but you can save money and give Bama a call as they can amend your tuner to include the features of this shift improver kit.
