An Expert’s Take on GM TCM Failures
As a technician, I’ve seen countless GMT360 platform vehicles like the Envoy, Trailblazer, and Rainier come in with these exact symptoms. The original TCMs are often mounted in the engine bay where they are subjected to constant heat cycles and vibration. Over time, this stress causes internal electronic components and solder joints to fail, leading to the communication errors and erratic shifting you’re experiencing. Simply replacing the unit with another used one won’t solve the problem, as it won’t be programmed for your vehicle. Our solution for the 2005 Envoy XUV TCM 24226863 is the smartest repair path—it provides a module with fresh, stable electronics and, most importantly, the correct software for your VIN, saving you hundreds in dealership fees and getting the job done right the first time.
Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) is essential because it allows us to load the exact, correct software from GM for your specific engine, transmission, and options. This makes the module a true plug-and-play part and ensures perfect communication with your vehicle’s other computers.
Is this part difficult to install?
The physical installation is straightforward for a DIYer with basic tools, as it’s a direct swap. It’s typically located in the LH (driver’s side) engine compartment. After installation, some vehicles may require a simple “relearn” procedure, which can often be done by following specific driving cycles. However, the critical and complex programming step is already done for you.
Will this fix my check engine light?
If your check engine light is on due to diagnostic trouble codes related to the TCM (such as P0700-series codes or U-series communication codes), then yes, this module is designed to resolve those issues. We always recommend clearing any codes after installation.
How do I know for sure my TCM is the problem?
While the symptoms listed above are strong indicators, the best way to be certain is with a proper diagnosis from a qualified mechanic using a professional scan tool. Common signs are a loss of communication with the TCM and specific transmission solenoid circuit faults. This part, the 2005 Envoy XUV TCM 24226863, is the most common point of failure for these symptoms.
What if my original part number isn’t 24226863?

What does the warranty cover?
This unit is backed by our one-year replacement warranty. This means that in the unlikely event the part fails within one year of the purchase date, we will provide a replacement unit.
