Useful Information

Description and Purpose:

This Genuine GM 6-Speed Transmission Control Module, marked with Part number: 19435615 in remanufactured condition, is what keeps your Silverado or Sierra shifting seamlessly. It monitors every gear change and ensures smooth, accurate transmission performance, whether you’re towing a load, driving in traffic, or hitting the highway. Think of it as the brain that makes your automatic gearbox feel precise and effortless.

Why Replacement is Important:

Without a properly working TCM, you might experience rough shifts, delayed engagement, or warning lights. A new module ensures reliable transmission control and consistent performance.
