Frequently Asked Questions
Do I need to program this module after I receive it?
Absolutely not. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. It will arrive ready for installation, with no additional programming required.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to submit it. We cannot ship your part until we have programmed it with your VIN.
Is this a difficult part to install?
The installation difficulty varies by vehicle model. On many vehicles like the Envoy or Trailblazer, the TCM is located in an accessible spot in the engine bay. For a DIY mechanic with basic tools, it is often a straightforward job. However, if you are not comfortable working on your vehicle, we always recommend professional installation.
Will this fix my transmission’s mechanical problems?
This module is designed to fix electronic faults originating from the TCM itself. It can resolve a wide range of shifting problems, communication errors, and false sensor codes. It will not fix internal mechanical failures like worn clutches or a bad torque converter. Proper diagnosis is key to a successful repair.
Is this compatible with other part numbers?
Yes. This module is a direct replacement for a range of GM part numbers, including 24223112, 24226863, 24233595, 24234189, 24239427, YBWW, YDFC, YDFD, YDLT, YJHY, YKTB, and YKTF. It will be programmed to function correctly for your specific vehicle.
