A Note From Our Lead Technician
“In my 20+ years turning wrenches, I’ve seen it all. With today’s complex 8 and 10-speed transmissions, the TCM is everything. We see too many truck owners waste hundreds, even thousands, chasing symptoms because they installed a module that wasn’t correctly programmed. A ‘blank’ module is just a paperweight. Our process ensures the TCM we send you is a perfect electronic match for your truck right out of the box. It’s the difference between a frustrating weekend and a job done right the first time.”

Frequently Asked Questions
How does the VIN programming process work?
It’s simple. After you place your order, you provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the latest GM factory software specific to your truck’s configuration. We then flash this software onto the TCM before shipping it to you. This makes the unit ready for installation upon arrival.
Is this a brand new part?
This is a genuine, fully tested OEM component that has been verified to meet or exceed all factory specifications. Each module undergoes a rigorous inspection and programming process to ensure reliability and performance.
Will I need to perform any additional steps after installation?
This module is designed for a direct, plug-and-play installation. In most cases, no further action is needed. We do recommend disconnecting the battery during the swap and allowing the vehicle’s systems to fully recognize the new module upon reconnection. Any pre-existing trouble codes should also be cleared.
How can I be sure this will fix my problem?
This part is a direct solution for issues caused by a faulty TCM, including common communication codes (like U0101) and erratic shifting behavior. While proper diagnosis is always recommended, a failing module is one of the most common causes for these symptoms in modern GM trucks. Our Programmed 2020-2022 Sierra 2500 TCM is the correct fix for a confirmed module failure.
What if I provide the wrong VIN?
The VIN is critical for correct programming. Please double-check the 17-digit VIN from your driver’s side door jamb sticker or dashboard plate before submitting it. An incorrect VIN will result in an incorrectly programmed module that will not function in your vehicle. We are not responsible for issues arising from an incorrectly supplied VIN.
Which exact part number will I receive?
You will receive a genuine GM module that is 100% compatible with all service numbers listed, including 24042698, 24043411, 24043413, 24289415, and 24296206. The module will be programmed specifically for your truck’s VIN, making the service number on the sticker secondary to the correct software inside.
