About this product

Power your Chevrolet, Buick, GMC, or Cadillac vehicle with a Genuine GM Parts 6L50 Remanufactured 6-Speed Automatic Transmission Assembly. Designed for rear-wheel and all-wheel drive vehicles, these automatic transmissions are electronically controlled for smooth shifts and durability. The modular design of the 6L50 is shared with variants rated for different torque levels to accommodate various engines and vehicle applications. All versions share a unique output gearset configuration that enables a wider range of ratios than conventional planetary gearset automatic transmissions. This allows the transmission to be tailored for optimal performance while delivering excellent acceleration traits. Remanufacturing transmissions is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear and failure with new components. Damaged and obsolete parts are replaced and are end of line tested to help ensure they perform to General Motors specifications and high-quality standards. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. Only Genuine GM Parts are tested to meet GM Original Equipment standards and are designed specifically to fit your vehicle.
