Frequently Asked Questions
Do I need to get this TCM programmed after I receive it?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. It arrives ready for a direct, plug-and-play installation.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We will provide clear instructions on how to do this. We cannot ship your order until we receive and validate your VIN.
Will this fix my specific transmission problem?
This module will resolve issues directly caused by a faulty TCM, such as communication errors (like code U0101), and erratic behavior due to internal electronic failure. While it solves many common transmission problems, it will not fix internal mechanical issues like worn clutches or a bad valve body. We always recommend having a professional diagnose the issue and check for relevant trouble codes.
Where is the TCM located on my truck?
For most of the listed Silverado and Sierra models, the TCM is located on the driver’s side of the vehicle, mounted to the core support or frame rail, typically under the hood. For the Camaro, it is found on the LH frame rail under the hood.
Is this a brand new part from GM?
This is a high-quality, fully tested replacement part that meets or exceeds original equipment specifications. It is loaded with official, up-to-date GM software specific to your vehicle.
What if this doesn’t fit my vehicle?
By programming the module to the VIN you provide, we ensure compatibility. Please double-check the fitment list and your original part number. If you are unsure, contact us with your VIN before ordering and we can verify fitment for you.
