ATK 9714AA Remanufactured Automatic Transmission Features:
Our remanufactured transmissions have improved torque converters included with every transmission to eliminate the possibility of front seal leaks, vibration or premature bushing wear, All torque converters are tested for leaks, lock-up, concentricity and balance. Every fully remanufactured valve body, with complete system correction and recalibration kit, is tested independently and includes updated throttle valve, manual valve, 4-spool switch valve, pressure regulator valve and governor plugs for improved shifting, lubrication and performance. All wear-prone valves are restored to stringent specifications and vacuum tested to confirm proper function. Each remanufactured transmission is hot, cold, load and simulated road testing.
