End Your Transmission Headaches for Good
Is your 2005 GMC Envoy, Trailblazer, or other GM vehicle suffering from erratic shifting, getting stuck in gear, or throwing a check engine light? A failing Transmission Control Module (TCM) is one of the most common causes of these frustrating and potentially dangerous issues. Don’t let a faulty module keep you off the road. This is the definitive, plug-and-play solution designed to restore your vehicle’s performance and your peace of mind.
Common Symptoms & Your Solution
A failing TCM can manifest in various ways, often starting subtly and getting worse over time. If you’re experiencing any of the following, this module is the reliable fix you need:
- Harsh or delayed shifting between gears
- The transmission getting stuck in one gear (limp mode)
- Inaccurate or erratic speedometer readings
- Check Engine Light with transmission-related Diagnostic Trouble Codes (DTCs) like P0700, P0753, P0758, or P0740
- Complete loss of gear engagement
Instead of paying for expensive diagnostic fees and dealership programming, this module arrives at your door ready for installation. We take your vehicle’s unique Vehicle Identification Number (VIN) and flash the module with the latest factory software from GM. This ensures a perfect match and seamless communication between your engine, transmission, and other vehicle systems. This is the most efficient way to get your truck or SUV running right again.

From the Technician’s Bench: A customer brought in a 2005 Trailblazer EXT with the 8-cylinder engine. It was stuck in 3rd gear, making it nearly undrivable. The codes pointed to a faulty TCM. Instead of just selling them a generic part that would need programming, we provided a VIN-matched unit just like this one. The customer, a capable DIYer, was able to swap the part in his driveway in under an hour. The truck immediately started shifting perfectly, the check engine light was gone, and he was back on the road without a tow truck or a massive repair bill. That’s the power of getting the right part, programmed correctly from the start.
This is the ideal solution for anyone looking for a reliable and straightforward fix for their transmission issues. By ordering a properly programmed 2005 Envoy TCM, you are not just buying a part; you are buying confidence in your vehicle’s ability to perform when you need it most.
Frequently Asked Questions
Do I need to program this module?
No. This is the main benefit of our service. We program the TCM using the VIN you provide during checkout. When you receive it, it is ready for installation with no further flashing or programming required.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we have this information to program it correctly.
Where is the TCM located on my 2005 Envoy?
On the 2005 GMC Envoy with the 8-cylinder engine, the TCM is typically located in the engine compartment on the driver’s side (LH side). Location can vary slightly on other compatible models, so we recommend consulting a service manual for your specific vehicle.
Will this fix my specific transmission problem?
This module corrects issues directly caused by a failing TCM. While it resolves the most common transmission electronic faults, it’s essential to ensure your vehicle’s transmission is mechanically sound. This part is a critical component for a complete repair when diagnostic codes point to a faulty 2005 Envoy TCM.
Is this compatible with other part numbers?
Yes. This module is a direct replacement for a wide range of part numbers, including 24226863, 24233595, 24234189, 24239427, and others listed in the description. Programming to your VIN ensures it functions correctly regardless of the original part number.
