B&M offers a range of "kits" that will give your automatic transmission anything from a subtle improvement, all the way to that race-car like shift a B&M transmission is famous for. Kits are complete with everything you'll need for your upgrade.

B&M® specializes in performance automatic transmissions, torque converters, SFI-approved flexplates, legendary automatic shifters, precision manual shifters, and many other transmission products, including cast deep aluminum transmission pans, transmission coolers, and automatic transmission fluids. B&M Racing and Performance has been at the vanguard of the growing automotive aftermarket since the early 1950s. Racers themselves, B&M’s founders identified the needs of local racers and street performance enthusiasts and developed products to fill those needs. As the industry grew, so did B&M. And as racers went faster, B&M developed products to help them break the records they just set.
