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 setup, providing firm positive shifts without sacrificing driver comfort, enhancing performance in all street vehicles, ideal for performance street driving or towing. The second option is our STREET/STRIP setup, delivering distinctly firm positive shifts that you can feel, even causing tire chirping with somewhat aggressive shifting. This setting is recommended for high-performance street/strip use or competitive events where you desire the hardest, quickest shifts from a shift improver kit. Note: Not compatible with GM TH4L60 (non-electronic) transmissions.
