The B&M® Shift Improver kits™ offer two distinct options for recalibrating your 1982-1993 GM TH700R4/4L60 automatic transmissions. The first is the HEAVY DUTY configuration, providing firm positive shifts without compromising driver comfort for enhanced performance in all street vehicles. This option is well-suited for performance street driving or towing applications. The second option is our STREET/STRIP setup, delivering unmistakably firm positive shifts that can be felt, with the potential to easily chirp the tires during more aggressive shifts. This configuration is recommended for high-performance street/strip use or competitive events when seeking the hardest, quickest shifts achievable from a shift improver kit. Note: Not compatible with GM TH4L60E (electronic) transmissions.
