Is Your Uplander’s Transmission Acting Up?
If you’re dealing with a 2006, 2007, 2008, or 2009 Chevrolet Uplander that’s shifting harshly, refusing to shift, or stuck in limp mode, a failing Transmission Control Module (TCM) is the most likely culprit. As an automotive diagnostician with over two decades of experience, I’ve seen this exact issue countless times. The TCM is the brain of your automatic transmission, and when it fails, it can cause a cascade of frustrating and potentially damaging problems. This isn’t just an inconvenience; it’s a critical failure that affects your vehicle’s safety and drivability.
“A customer’s 2008 Uplander came into my shop last week with a check engine light and it was stuck in 3rd gear. The codes pointed to a faulty shift solenoid, but after replacing it, the problem persisted. My experience with these vans immediately pointed me to the TCM. We found the original module, located at the LH strut tower, had internal circuit failure from years of heat cycles. A quick swap with a pre-programmed module like this one had the van shifting perfectly in under 20 minutes. It’s a textbook repair for these symptoms.”

Plug-and-Play Installation: No Dealer Visit Required
Installing this module is a straightforward job that most DIY mechanics can handle in their own driveway. For the 2006-2009 Uplander, the TCM is conveniently located. Follow these simple steps:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the Module: On the Uplander, you’ll find the TCM mounted to the driver’s side (LH) strut tower in the engine bay.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note the tab locations to avoid breaking them. Then, unbolt the old module from its bracket.
- Install the New Module: Bolt the new, pre-programmed module into place. Securely reconnect the electrical harnesses, ensuring they click into place.
- Final Steps: Reconnect the battery terminal. Start the vehicle and let it idle for a few minutes. While not always necessary, using a basic OBD2 scanner to clear any stored fault codes is good practice.
