There’s nothing more frustrating than a truck that won’t shift right. When your Sierra or Silverado is your tool for getting the job done, transmission problems mean lost time and lost confidence. Harsh shifts, warning lights, or getting stuck in gear can sideline your vehicle when you need it most. This is the definitive solution to restore the crisp, reliable performance your GM truck is known for. This Transmission Control Module (TCM) arrives at your door professionally programmed to your vehicle’s specific VIN, eliminating the need for an expensive trip to the dealership for programming.

Expert Insight: More Than Just a Part
We recently worked with a contractor whose 2021 Silverado 2500 was stuck in limp mode. Every day his truck was down, he was losing money. He was worried about a full transmission rebuild, but diagnostics pointed to the TCM. Instead of having his truck towed to a dealer and waiting days for an appointment and programming, he ordered this module. We programmed it to his VIN and shipped it overnight. He installed it the next day in his own shop and was back on the job site that afternoon. For modern, computer-controlled transmissions, the programming is just as critical as the hardware. This isn’t just a component; it’s a complete, ready-to-go solution that respects your time and your truck’s importance.
Don’t let a faulty module dictate your truck’s reliability. Take control with a dependable, correctly prepared Programmed 2020-2022 Sierra 3500 TCM and get back to work with the confidence you deserve.
Frequently Asked Questions
Do I need to do any programming myself?
No. The main benefit of this part is that we handle all the programming for you. After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. We then flash the module with the correct, most up-to-date software from GM specifically for your truck. It arrives ready to install.
Where do I provide my VIN?
After you complete your purchase, we will contact you for your VIN. For a faster process, you can add your VIN to the ‘notes’ section during checkout.
Will this fix my harsh shifting problem?
While a faulty TCM is a very common cause of harsh shifting, communication errors, and limp mode, we always recommend a proper diagnosis by a qualified technician. This part is designed to solve issues directly caused by a failed TCM.
Is this part compatible with my 2021 Silverado 2500?
Yes, it is. This module fits a range of GM vehicles, including the 2020-2021 Silverado 2500/3500 and 2020-2022 Sierra 2500/3500. Please review the full compatibility list on this page to confirm your specific make and model.
What happens if I don’t provide a VIN?
We cannot ship the module until we have your VIN. The programming is essential for the part to function in your vehicle. An unprogrammed module will not work correctly and may cause further issues.
