Frequently Asked Questions
What does “VIN programmed” actually mean?
It means we load your vehicle’s unique Vehicle Identification Number (VIN) and the latest GM software onto the module before we ship it. This ensures it communicates perfectly with your truck’s engine computer and other systems right out of the box, just like an original part from the dealer, but without the programming cost.
Is this a difficult part to install myself?
For most DIYers with basic tools, this is a straightforward job. On the 2007 Sierra, the TCM is typically located next to the battery in the engine compartment. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It usually takes less than 30 minutes.
Will this module fix my specific transmission code (e.g., P0753)?
This module is designed to fix issues originating from a faulty computer. While it resolves many common codes like P0700, it’s important to ensure the code isn’t being caused by a mechanical or wiring issue (like a bad solenoid or damaged harness). A proper diagnosis is always recommended, but a faulty TCM is a very common failure point for these symptoms.
Do I need to send my old module back?
No, there is no core charge for this part. You can keep your old module, which saves you the time, cost, and hassle of return shipping.
How can I be sure my TCM is the problem?
Common signs include multiple transmission-related codes, erratic shifting that isn’t tied to a specific gear, and intermittent electrical behavior. If the transmission fluid is clean and at the correct level, and there are no obvious mechanical failures, the TCM is a primary suspect. This 2007 GMC Sierra 2500 transmission control module is the most common solution for these electronic failures.
