Experiencing harsh, erratic shifts, a flashing check engine light, or the unnerving feeling of your transmission getting stuck in gear?

Common Symptoms & Your Direct Solution
A failing TCM can manifest in various ways, often triggering Diagnostic Trouble Codes (DTCs) like P0700, P0751, P0756, or P0761. If you’re noticing any of the following issues, a faulty module is the likely culprit:

- Inaccurate speedometer readings
- Decreased fuel economy
- Illuminated Check Engine Light

Frequently Asked Questions

Where can I find my vehicle’s VIN?
Your 17-digit VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
How difficult is the installation?
For the 2005 Envoy XL, the TCM is typically located in the engine compartment on the driver’s side.

We recommend installation by a qualified mechanic if you are not comfortable with automotive electrical work.
