4L60E 4-Speed Automatic Transmission

The GM Genuine Parts 10184T is a fully remanufactured 4-speed automatic transmission for the 4L60E transmission family. It is built to meet or exceed original equipment specifications and comes with a comprehensive 7-year, 1-million-mile warranty, including free core return shipping. The remanufacturing process involves teardown, triple cleaning, chasing all threads, and installing new bushings. The valve body is rebuilt and tested using a C.A.R.S. system, and all new o-rings, gaskets, and seals are used during reassembly. Each unit undergoes custom dyno testing to ensure readiness for the road. Improvements specific to the 4L60E/4L65E are implemented, including updated boost valve/sleeve and new forward/reverse abuse plugs to correct engagement issues. Enhanced torque converter clutch performance is achieved by replacing the TCC control valve, regulator valve, and AFL valve to prevent slipping and lockup problems. Upgraded electronic pressure controls are installed to resolve erratic shifting, and OEM plastic accumulator pistons are replaced with durable aluminum ones, while weak OE sun shells are updated to a hardened design. All internal bushings are replaced with custom-spec components to ensure hydraulic integrity. This transmission is specifically designed to fit the 2006 Chevrolet Silverado 1500 2WD and GMC Sierra 1500 2WD models. It is crucial to verify fitment by checking application notes and VIN code/cast number before ordering, as the product may not fit all vehicles. Always confirm your specific vehicle's compatibility before purchase.
