GM 4WD 6L90 6SPD TRANS

Remanufactured automatic transmission assembly with an improved torque converter to prevent leaks, vibration, and premature bushing wear. Torque converters are tested for leaks, lock-up, concentricity, and balance. The valve body is fully remanufactured with a complete system correction and recalibration kit, independently tested, and includes updated valves (throttle, manual, 4-spool switch, pressure regulator, governor plugs) for enhanced shifting, lubrication, and performance. Wear-prone valves are restored to stringent specifications and vacuum tested. Each transmission undergoes hot, cold, load, and simulated road testing. Backed by a nationwide limited warranty.
