The B&M® Shift Improver kits™ provide two distinct options for recalibrating your 1988-1994 GM TH400 and TH475 automatic transmissions. The first option is the HEAVY DUTY setup, ensuring firm positive shifts without compromising driver comfort, enhancing performance in all street vehicles. This is an excellent choice for those engaged in performance street driving or towing. The second option is our STREET/STRIP setup. Be forewarned, this setting will deliver firm positive shifts that are distinctly perceptible, capable of easily chirping the tires during more assertive shifts. This configuration is recommended for high-performance street/strip applications or competitive events when you seek the most robust and quickest shifts attainable from a shift improver kit.
