About this product

GM Genuine Parts Transmission Control Modules are designed, engineered, and tested to rigorous standards, and are backed by General Motors. When you start experiencing harsh shifting, unexpected gear slipping, or delayed engagement when shifting into drive or reverse, replacing these vital components can restore a smooth and predictable driving experience. Acting as the electronic brain of your drivetrain, these modules communicate directly with the engine computer and vehicle sensors to calculate the exact moment for gear changes based on engine speed, throttle position, and load. Whether you are navigating daily stop-and-go commutes, cruising on the highway for optimal fuel efficiency, or towing heavy loads up steep grades, they adapt gear selection to ensure reliable power delivery. Engineered to maintain proper transmission operation in severe hot or cold weather, this module is rigorously validated to clear transmission-related fault codes and deliver consistent, long-lasting performance. Available in new General Motors parts for original factory quality and in remanufactured and refurbished options restored to GM standards. GM Genuine Parts are the true OE parts installed during the production or validated by General Motors for GM vehicles.
