The B&M® Shift Improver kits™ feature two options to recalibrating your 1988-1994 GM TH400 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.
