Frequently Asked Questions
Will this module fit my 2008 Suburban 1500?
Yes, this T42 TCM is guaranteed to be a direct-fit, VIN-programmed replacement for the 2007 and 2008 Chevrolet Suburban 1500 models. It is also compatible with a wide range of other GM vehicles from that era, including the Tahoe, Silverado, and Yukon.
Is this part difficult to install?
Installation is straightforward for someone with basic mechanical skills. The TCM is typically located in the engine compartment next to the battery. You simply disconnect the battery, unplug the electrical connectors from the old module, unbolt it, and install the new one. No special programming tools are required.
What does “VIN Programmed” actually mean for me?
“VIN Programmed” means we load your vehicle’s unique 17-digit VIN into the module before shipping it. This ensures the TCM communicates perfectly with your Suburban’s engine computer and other systems, just like the original part from the factory. It makes the installation a true plug-and-play process.
Do I need to send my old TCM back?
No, there is no core charge for this part. You can keep your old module, which saves you the time and hassle of packaging and shipping it back to us.
Will this fix a P0700 check engine light code?
A P0700 code is a general transmission fault code, indicating that the TCM has detected a problem. In many cases, replacing a faulty 2007-2008 Suburban 1500 TCM will resolve the underlying issue causing the P0700 and related codes. After installation, we recommend clearing all codes with a standard OBD2 scanner.
