  • The B&M Shift Improver kits feature two options to recalibrating your 1965-1987 GM TH400, TH375 and TH475 automatic transmissions. First is the HEAVY DUTY set-up, giving you firm positive shifts without loss of driver comfort for improved performance in all street vehicles. This is a great option for performance street driving or towing. The second is our STREET/STRIP set-up. Be warned, this will deliver firm positive shifts you will feel, along with easily chirping the tires when shifting somewhat aggressively. This setting is recommend for high performance street/strip use, or for competitive events when you want the hardest, quickest shifts possible from a shift improver kit.

  • Since the very early 1950s, B&M has been at the vanguard of the growing automotive aftermarket. 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.

    In the 50s it was B&M who came up with the idea of using a performance reinforced Hydramatic for racing. In the 60s it was B and M who developed shifters to go along with it, and later in the decade came race converters. In the 70s shift and transmission improving kits, and always the constant refinements and expansion of existing product lines.

    If you've ever raced a vehicle, or driven a hot rod with an automatic transmission, high stall torque converter, an aftermarket automatic shifter, or performance enhancing shifting kit - thank B&M. From Trick Shift performance ATF to reverse pattern valve bodies, 1.80 gear sets to cool canisters, the list of firsts goes on and on.
