On the 2006-2019 Chevrolet Silverado 3500HD, the Transmission Control Module (TCM) mounted internally on the Allison 1000 transmission fails due to heat exposure and vibration. The internal TCM is bathed in transmission fluid and subjected to extreme temperatures. When it fails, the transmission goes into limp mode or refuses to shift from 3rd gear.

Common Symptoms

Transmission stuck in 3rd gear
