Frequently Asked Questions
What does a transmission control module do on a Sierra 1500?
The TCM acts as the brain for your automatic transmission. It uses data from various sensors to control when the transmission shifts gears, how firm the shifts are, and when the torque converter locks up. A properly functioning TCM is essential for performance, fuel economy, and transmission health.
Is this TCM difficult to install?
No, installation is generally simple for someone with basic mechanical skills. On most 2007-2013 Sierra 1500 models, the TCM is located in the engine bay, often next to the battery. You simply disconnect the battery, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. The entire process typically takes less than 30 minutes.
How do I know this is the correct part for my truck?
This module fits 2007-2013 GMC Sierra 1500 trucks with 4-speed automatic transmissions. The best way to confirm is to match the part number on your existing module to one of the compatible numbers listed (e.g., 24239224, 24252114). During checkout, we require your VIN to ensure we program it perfectly for your specific vehicle configuration.
Does this module require any additional programming?
No. The main benefit of our module is that it arrives 100% pre-programmed to your truck’s VIN. It is a true plug-and-play solution, saving you the time and expense of a dealership visit for programming.
What happens if I install a TCM that isn’t programmed to my VIN?
An unprogrammed or incorrectly programmed TCM will not communicate properly with your truck’s other computers, like the Engine Control Module (ECM). This can result in the vehicle not starting, not shifting out of park, or exhibiting the same or worse shifting problems than the faulty unit you’re replacing.
Will this fix a P0700 code?
A P0700 code is a general fault code indicating that the TCM has detected a problem and has requested the check engine light be turned on. While this module often resolves the underlying issue causing the P0700, it’s important to use a scanner to check for other specific codes (like P0750 for a shift solenoid) that the TCM has stored.
