Restore Your Tahoe’s Shifting Performance
Is your 2007-2009 Chevrolet Tahoe suffering from erratic shifting, delayed gear engagement, or getting stuck in limp mode? These are classic signs of a failing Transmission Control Module (TCM), the electronic brain that governs your automatic transmission’s behavior. A faulty TCM can turn a reliable SUV into an unpredictable and frustrating vehicle to drive. This genuine OEM-quality GM T42 TCM, part number 24234503, is the definitive solution to restore the smooth, responsive performance you expect from your vehicle.
The TCM is responsible for interpreting data from various sensors to command precise gear changes, manage torque converter lockup for fuel efficiency, and monitor the overall health of your transmission. When it begins to fail, communication breaks down, leading to a host of drivability issues and diagnostic trouble codes (DTCs) like P0700. Our module is expertly programmed to your vehicle’s specific VIN, ensuring it works perfectly right out of the box without requiring a costly trip to the dealership for additional programming.
From the Diagnostic Bay
We had a 2008 Sierra come in with what the owner was sure was a failing shift solenoid. He’d spent a weekend dropping the transmission pan and replacing the solenoid pack, only to have the same harsh 1-2 shift and a P0752 code return immediately. After a quick scan, we saw erratic data from the TCM. We installed one of our VIN-programmed T42 modules, cleared the codes, and the truck shifted like it just rolled off the assembly line. He could have saved himself a messy weekend and hundreds of dollars by diagnosing the module first. The TCM is often the root cause when multiple solenoid codes appear simultaneously.
Solving Common Transmission Problems with a 2007-2009 Tahoe TCM
Replacing your failing module is not just about fixing a current annoyance; it’s about preventing further damage to your transmission’s mechanical components. Continued operation with a faulty TCM can lead to excessive wear on clutches and bands, resulting in a much more expensive repair down the road. This replacement part is engineered to meet or exceed original GM specifications, providing a dependable, long-term fix for your transmission woes.

We recommend using a basic scan tool to clear any stored DTCs after installation is complete.
Frequently Asked Questions
What does “VIN Programmed” actually mean?
It means we load the module with your specific vehicle’s Vehicle Identification Number (VIN) and the corresponding factory software from General Motors. This makes the module communicate perfectly with your engine computer and other systems, just like the original part did. It’s a crucial step that allows for a true plug-and-play installation.
Can I install this 2007-2009 Tahoe TCM myself?
Absolutely. If you are comfortable using basic hand tools and can locate the module in your engine bay (usually near the battery), this is a very straightforward DIY repair that can be done in less than 30 minutes. No special diagnostic tools are required for the installation itself.
How do I confirm this part fits my vehicle?
This module fits a wide range of 2006-2014 GM vehicles. The best way to confirm fitment is to match the part number 24234503 or one of the interchangeable numbers listed in the description. You can also use our website’s vehicle selector or contact our expert support team with your VIN.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, which saves you time and money on return shipping.
What happens if I don’t replace a failing TCM?
Continuing to drive with a bad TCM can lead to poor fuel economy, unpredictable shifting, and potentially leave you stranded. More importantly, it can cause premature wear and tear on the internal mechanical parts of your transmission, leading to a much more costly full transmission rebuild in the future.
