I offer the modified TransGo Performance Shift kit to give quicker and firmer shifts at WOT, but also smoother shifts at part throttle. You do not need firm shifts at part throttle as they are hard on the geartrain (splines), as it will wear out the transmission pre-maturely, can be dangerous in the rain, it attracts cops, and the biggest reason, women hate it.... I modify the Shift kit to match what is done to the motor, rear end gear ratio, the diameter and stall of your torque converter, and how you drive. Sometimes the larger Sonnax 2nd apply servo and the 4th apply servos are needed depending on what you have here. Call me with any questions.
