Frequently Asked Questions
What does a Transmission Control Module do?
The TCM acts as the brain for your automatic transmission. It receives data from various sensors on the engine and vehicle, and uses that information to control exactly when and how the transmission shifts gears, ensuring optimal performance, fuel efficiency, and smoothness.
Is this a difficult part to install myself?
For someone with basic mechanical skills, this is a very manageable job. On the 2007-2008 Suburban, the TCM is typically located in the engine bay next to the battery. 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.
Do I need to send my old TCM back?
No. We do not require you to return your original part. There is no core charge associated with this purchase, making the process faster and more convenient for you.
How do I know this is the correct part for my Suburban?
This module is a direct replacement for service number 24239224 and is guaranteed to fit 2007-2008 Chevrolet Suburban 1500 models. During checkout, we require your vehicle’s VIN to ensure we program it with the exact software for your specific configuration.
Will this module fix my specific error code, like P0700?
A P0700 code is a general fault code indicating the TCM has detected a problem. This module is designed to fix the internal electronic failures that cause the TCM to set this code and other related transmission codes. Once the new, properly functioning 2007-2008 Suburban 1500 Transmission Control Module is installed, these codes can be cleared and should not return.
