GM RWD 6L80 6SPD

Remanufactured transmission with improved torque converters (tested for leaks, lock-up, concentricity & balance) to eliminate front seal leaks, vibration, or premature bushing wear. Features a fully remanufactured valve body with system correction and recalibration kit, independently tested, and includes updated throttle valve, manual valve, 4-spool switch valve, pressure regulator valve, and governor plugs for enhanced shifting, lubrication, and performance. All 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. Transmissions are completely disassembled, checked, and reassembled to spec for tolerances, vacuum, seal & balance, with all wear parts replaced and simulated tested. Securely packaged in a recyclable container for core return. Dyno tested for trouble-free service and longevity.
