End Your Transmission Troubles and Restore Smooth Driving
Is your 2006-2009 GMC Envoy suffering from harsh, erratic shifting, getting stuck in gear, or displaying a persistent check engine light? These are classic signs of a failing Transmission Control Module (TCM), a critical component that acts as the brain for your automatic transmission. Ignoring these symptoms can lead to more significant damage and costly repairs. This VIN-programmed T42 TCM is the definitive, reliable solution to get your SUV back to peak operational condition quickly and affordably.

Expert Insight: Why VIN Programming is Non-Negotiable
A generic, un-programmed TCM from a parts store is effectively a blank slate. Installing it will not solve your problem, as it cannot communicate with your Envoy’s engine computer (ECU), anti-lock brake system, or other vital modules. Our VIN programming service writes your vehicle’s unique operational data directly onto the module before it ships. This ensures that the moment you plug it in, it integrates seamlessly with your vehicle’s electronic ecosystem, just like the original part did. This is the key to a successful, one-time repair.
Whether you’re a seasoned DIY mechanic or having your trusted technician perform the work, installing this GMC Envoy 24252114 transmission control module is a straightforward process. It is typically located in the engine compartment and can be swapped in under 30 minutes. Regain control of your vehicle’s performance and dependability with a part engineered to solve the problem right the first time.
Frequently Asked Questions
What does a VIN-programmed TCM actually do?
VIN programming loads your vehicle’s specific software and calibration files onto the module. This allows it to control shift timing, line pressure, and torque converter functions perfectly for your Envoy’s engine and drivetrain configuration, ensuring optimal performance and fuel efficiency.
Is this a difficult part to install myself?
For most individuals with basic mechanical skills, this is a very manageable job. The TCM is usually easily accessible in the engine bay. The key steps are disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. Since it’s pre-programmed, no further electronic setup is required.
Will this module fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the underlying issue causing the P0700, it’s always wise to use a scanner to check for more specific codes (like solenoid faults) to confirm the TCM is the source. In many cases, a new, properly functioning GMC Envoy 24252114 transmission control module is the correct fix.
Do I need to send my old part back for a core charge?
No, there is no core charge associated with this part. You can keep your old module without any extra hassle or cost, simplifying the repair process.
How can I be sure this is the right part for my vehicle?
Please match your vehicle’s year, make, and model to our detailed fitment list. The most accurate way to ensure compatibility is to cross-reference the service number printed on your original TCM with the numbers listed in our description, such as 24252114, 24242391, or 24234503.
