Recalibrate your governor to ensure that your transmission still performs like it should after you make modifications to your car like a rear gear swap or tires.
When you’re changing rear gear ratios and tire sizes, the shift points on a TH350, TH400 or 700R4 transmission will need to be changed to keep the engine in its optimal operating range. The TCI GM Governor Recalibration Kit provides an easy way to make modifications and adjustments to the transmission governor. Featuring a wide range of weights and springs, the kit allows users to make multiple changes as needed to fine tune shift points at both part throttle and wide open throttle. The universal design is compatible with a variety of GM transmission applications, and easy-to-follow instructions allow for quick installation in fewer than 60 minutes. The TCI GM Governor Recalibration Kit will greatly improve both peak performance and drivability of your vehicle.
