Tired of Erratic Shifting and Transmission Worries?
Is your 2005 GMC Envoy XUV or other GM vehicle suffering from harsh shifts, getting stuck in gear, or throwing confusing transmission codes? A failing Transmission Control Module (TCM) can turn a reliable vehicle into a source of constant stress, leaving you stranded or facing an expensive, uncertain repair. This isn’t just an inconvenience; it’s a compromise on your vehicle’s performance and your safety. We offer a direct, reliable solution with our pre-programmed 2005 Envoy XUV Programmed TCM 24234189, designed to restore your transmission’s peak performance and your confidence on the road.
Common Symptoms & Your Direct-Fit Solution
A faulty TCM can manifest in various ways, often being misdiagnosed as an internal transmission failure. If you’re experiencing any of the following, this module is the most likely solution:
- Abrupt, harsh, or delayed shifting
- Transmission getting stuck in one gear (limp mode)
- Check Engine Light or other warning lights illuminated
- Diagnostic Trouble Codes (DTCs) such as P0740, P0753, P0758, or P1860
- No communication between your scan tool and the TCM
- Inaccurate or erratic speedometer readings
Our TCM arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the module has the correct software and calibrations for your exact engine, axle ratio, and tire size, eliminating the need for an expensive trip to the dealership for programming.

Expert Insight: Why VIN-Programming is Non-Negotiable
Many sellers offer unprogrammed or generically programmed TCMs, but this is a recipe for problems. A 2005 GM vehicle’s TCM is not a one-size-fits-all part. The software it needs is highly specific to the VIN. This number tells the module everything from which engine it’s paired with to the final drive ratio in the axles. Using the wrong programming can lead to incorrect shift points, poor fuel economy, and even damage to your transmission over time. By providing your VIN, you ensure our technicians load the exact factory calibration file for your vehicle. This is the secret to a successful, lasting repair, and it’s a service we provide on every single 2005 Envoy XUV Programmed TCM 24234189 we ship.
Frequently Asked Questions
Do I need to do any programming after installation?
No. The module comes fully programmed to your VIN. After installation, you may need to perform a simple idle relearn procedure, which typically involves letting the vehicle idle for a few minutes. We include instructions to guide you through this easy process.
Where do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.
How do I know if the TCM is actually the problem?
While the symptoms listed above are strong indicators of a failing TCM, proper diagnosis is always recommended. Common signs include specific transmission solenoid codes (like P0753/P0758) and a complete loss of communication with the module when using a professional scan tool. If your mechanic has diagnosed a bad TCM, this is your solution.
Will this fit vehicles other than the Envoy XUV?
Yes. This module is compatible with a wide range of 2004-2005 GM vehicles, including the Trailblazer, Rainier, Corvette, GTO, Grand Prix, and more, as specified in the fitment list. The key is that we program it specifically for the VIN you provide.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty. We stand behind our products to give you confidence in your purchase.
Is this part difficult to install?
The physical location of the TCM varies by model (e.g., in the engine compartment on an Envoy, under the air cleaner housing on a LaCrosse). For most models, it is a straightforward process involving disconnecting the battery, unplugging electrical connectors, and unbolting the module. It is a very manageable job for a DIYer with basic tools.
