Expert Insight: The Power of Proper Programming
A generic, non-programmed TCM might seem like a cheaper option, but it often leads to more headaches. A heavy vehicle like the Suburban 1500 has specific transmission software parameters for towing, hauling, and managing its weight.

This is the key to a lasting repair and restored driver confidence.
Frequently Asked Questions
What does this Transmission Control Module do?
The TCM is the ‘brain’ of your automatic transmission. It receives data from various sensors on the engine and vehicle to control exactly when and how the transmission shifts gears, ensuring optimal performance, fuel efficiency, and smoothness.
Is this part truly plug-and-play?
Yes. During checkout, we require your vehicle’s VIN. We use this to program the module with the correct software for your specific 2007-2008 Suburban 1500. This means you can install it, clear any old codes with a scan tool, and drive away without any dealer intervention.
Where is the TCM located on my Suburban?
On the 2007-2008 Suburban 1500, the T42 TCM is typically located in the engine compartment, next to the battery. Installation is straightforward and can usually be completed in under 30 minutes with basic hand tools.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause, it’s crucial to diagnose any other potential issues. However, if the code is accompanied by shifting problems, a faulty 2007-2008 Suburban 1500 Transmission Control Module is the most common culprit.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep or dispose of your old module at your convenience, making the repair process simpler and faster.
