Restore Your Uplander’s Transmission Performance
Are you experiencing frustrating and unpredictable transmission issues with your 2006, 2007, 2008, or 2009 Chevrolet Uplander? Symptoms like harsh shifting, getting stuck in one gear (limp mode), or an illuminated Check Engine Light can point directly to a failing Transmission Control Module (TCM). This critical component is the brain of your automatic transmission, and when it malfunctions, it can make your vehicle unreliable and unsafe to drive. Put an end to the guesswork and costly diagnostic fees with our direct-fit, VIN-programmed T42 Transmission Control Module, part number 24240449.
From the Diagnostic Bay
We recently had a 2008 Uplander come into the shop that was perpetually stuck in 3rd gear. The owner was worried they were facing a complete transmission rebuild, a repair that can cost thousands. The scanner showed a generic P0700 code and a few solenoid circuit faults. Instead of starting a teardown, we checked the TCM. After installing one of our pre-programmed T42 modules, the van shifted perfectly through all gears on the test drive. The problem wasn’t a mechanical failure inside the transmission; it was a faulty electronic module. This simple replacement saved the customer a massive headache and a significant amount of money.
Signs You Need a New 2006-2009 Uplander TCM
A failing TCM can manifest in various ways, disrupting your vehicle’s drivability. If you notice any of the following issues, it’s a strong indication that your module needs replacement:
- ✔ Harsh, erratic, or delayed gear shifts.
- ✔ Vehicle is stuck in limp mode and will not shift out of 2nd or 3rd gear.
- ✔ The Check Engine Light or transmission warning light is on.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related codes are present.
- ✔ Complete failure to shift up or down, leading to poor acceleration.
- ✔ A noticeable decrease in fuel economy.
- ✔ Intermittent loss of communication with the module.

Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. This module comes fully pre-programmed to your vehicle’s specific VIN. It is ready for installation right out of the box, saving you time and the expense of dealership programming.
Where is the TCM located on my 2006-2009 Chevy Uplander?

Will this part fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module replacement often resolves the root cause of the P0700 code (such as internal solenoid driver faults), it’s always best to scan for more specific codes to confirm the diagnosis.
