Overview

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.

  • Perfect for Towing or Street/Strip Use
  • Eliminates Soft and Sluggish Shift
  • Recalibrates Stock Transmissions
  • Over 65 Years of B&M Quality
