The B&M Shift Improver kit offers two recalibration options for 1968-1981 GM TH350 automatic transmissions: Heavy Duty for firm positive shifts without loss of driver comfort, and Street/Strip for harder, quicker shifts. It eliminates soft shifts and shift overlap and improves transmission life. Does not fit TH350C lock-up transmissions.
