Stop Struggling with a Faulty Transmission in Your GM Truck or SUV
Is your 2007 Silverado 2500, Tahoe, or Sierra suffering from harsh, erratic shifting, getting stuck in gear, or throwing transmission codes? A failing Transmission Control Module (TCM) can cripple your vehicle, causing frustrating downtime and potential damage. Get your vehicle back on the road and shifting like new with this professionally programmed T42 Transmission Control Module. It’s the direct, no-nonsense solution designed to restore performance and reliability without an expensive trip to the dealership.
Common Symptoms & Your Solution
If you’re experiencing any of the following issues, a failing TCM is the likely culprit. This module is the definitive fix for:
- Harsh, banging shifts or delayed gear engagement.
- The vehicle being stuck in “limp mode” (usually 2nd or 3rd gear).
- An illuminated Check Engine Light or Transmission Warning Light with codes like P0700, P0750, or other solenoid-related faults.
- Failure to upshift or downshift, leading to poor acceleration and terrible fuel economy.
- Complete loss of communication with the transmission.
Instead of just replacing the part and hoping for the best, our VIN Programmed T42 TCM arrives ready for a true plug-and-play installation, ensuring all software is perfectly matched to your vehicle’s specific configuration from the factory.

An Expert’s Note on “Limp Mode”: Getting stuck in limp mode is your vehicle’s way of protecting the transmission from further damage. It’s a serious sign that the computer can no longer control shifts properly. Driving in this condition is not only frustrating but can cause excessive heat and wear. Installing a new VIN Programmed T42 TCM is the most effective way to restore full communication and control, getting you out of limp mode and back to full operational capacity safely.

Frequently Asked Questions
What is a T42 TCM and what does it do?
The T42 Transmission Control Module (TCM) is the electronic brain of your automatic transmission. It receives data from various vehicle sensors to control shift timing, torque converter lockup, and line pressure, ensuring smooth and efficient operation.
Is this module truly “plug-and-play”?
Yes. We program the module to the specific Vehicle Identification Number (VIN) you provide during checkout. This means it arrives with the correct software for your vehicle’s exact options and requires no additional programming from a dealer or mechanic.
How do I know if my TCM is the problem?
Common signs include erratic or harsh shifting, getting stuck in one gear (limp mode), and specific diagnostic trouble codes (DTCs) like P0700. While other issues can cause similar symptoms, these are classic indicators of a failing TCM.
Where is the T42 TCM located on my vehicle?
Location varies by model. On many GM trucks and SUVs like the Silverado and Sierra, it’s found in the engine compartment, often next to the battery or on a strut tower. On other models, it may be near the air cleaner box or on the frame rail. The provided fitment list gives common locations.
Do I need to send my old part back?
No. There is no core charge for this part. You can keep or dispose of your old module, making the repair process simpler and more convenient for you.
What if I install it and still have problems?
While this module is a direct fix for electronic failures, it’s important to ensure there are no underlying mechanical issues with your transmission (e.g., worn clutches, bad solenoids). Our expert support team is here to help, and the part is covered by a one-year replacement warranty for peace of mind.
