ZZPerformance was the first to break a pump shaft and we are proud to be the first to do something about it. Since we have learned that transmissions with high stall converters, raised line pressure and raised shift points are putting additional stress on the pump shaft.
Works in 4T65E and 4T65E-HD.
To replace the shaft the transmission must be removed from the car.
