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.

  • Chrome moly used to replace weaker factory metal
  • Smallest shaft diameter increased by .041
  • Machined teeth vs. rolled factory teeth
  • Lifetime warranty

To replace the shaft the transmission must be removed from the car.

Made really well compared to the stock shaft. I'm actually shocked on how bad my stock one looks but now that I have this no worries

The bullet proof Tranny!

A big shout out to ZZP for leading the industry in 4T65E and 4T65E-HD components! With their help I have assembled the ultimate HP capacity tranny...Thank you again. Will buy another complete kit again soon.

Must have.

I installed this part in my 1998 GTP coupe along with the 300M input shaft.It's obvious when you look at them side by side the difference.My ZZP TQ converter hydraulic pump seized "very loud" and nothing happened to the pump shaft!A+, highly impressed!
