The 6L90 transmission is a 6-speed automatic transmission developed by General Motors and introduced in 2007. Designed as a heavier-duty version of the 6L80, the 6L90 is part of GM’s Hydra-Matic series and built to handle higher torque and heavier loads. It is commonly used in vehicles like the Chevrolet Silverado HD, GMC Sierra HD, Cadillac Escalade, and Chevrolet Express vans.
The 6L90 boasts a torque capacity of up to 738 lb-ft, making it an ideal choice for trucks, vans, and SUVs used for towing, hauling, and other demanding applications. Its design includes advanced electronic controls, adaptive shift logic, and an expanded case to accommodate additional clutch packs for greater durability. While robust, some early models experienced torque converter issues and fluid overheating, which Certified Transmission’s remanufactured units address comprehensively.
