ATK rebuilds quality transmissions that go through vigorous testing and simulations to eliminate premature failures. Each transmission will include fluid and an application-specific torque converter that is tested for leaks, lock-up, concentricity, and balance. Fully-rebuilt valve bodies feature a complete system correction and recalibration kit that includes an updated throttle valve, manual valve, 4-spool switch valve, pressure regulator valve, and governor plugs for improved shifting, lubrication, and performance. ATK's attention to detail and quality will save you time and money by keeping your General Motors product out of the shop and on the road.
