Restore Flawless Shifting to Your 2005 GM Vehicle
Experiencing erratic shifting, harsh gear changes, or a transmission that seems to have a mind of its own in your 2005 GMC Envoy? A failing Transmission Control Module (TCM) is a common cause, leading to frustrating driving and potential damage.

Common Symptoms & Your Solution
If your vehicle is exhibiting any of the following symptoms, a faulty TCM is the likely culprit:

- The vehicle gets stuck in one gear (often called “limp mode”).
- Check Engine Light or other warning lights are illuminated on the dash.
- Diagnostic Trouble Codes (DTCs) related to solenoids (e.g., P0753, P0758, P0740) or loss of communication.

Expert Insight: Don’t Replace the Transmission, Replace the Brain!
We recently worked with a customer whose 2005 Rainier was stuck in third gear. His mechanic, seeing solenoid codes, quoted him thousands for a transmission rebuild. Suspecting a different issue, he called us. We identified his symptoms as a classic TCM failure. He ordered this exact programmed 2005 Envoy TCM, installed it in under an hour, and his SUV was shifting perfectly again. This simple swap saved him a massive repair bill and weeks of downtime. Before you condemn your transmission, always check its control module first.
