Is Your Family’s Uplander Shifting Unreliably?
A failing transmission control module in your 2006-2009 Chevrolet Uplander can turn your dependable family minivan into a source of stress.

This pre-programmed T42 Transmission Control Module is the definitive solution to restore the smooth, predictable performance your family relies on every day.
Common Symptoms & Your Solution
A faulty TCM can manifest in several frustrating ways. You might notice your Uplander refusing to shift, delayed engagement from park to drive, or slipping between gears. Often, the vehicle will enter a protective “limp mode,” locking you into a single gear and making driving difficult. These issues are typically accompanied by diagnostic trouble codes (DTCs) like P0700, P0750, or various solenoid-related faults. Our expertly programmed Uplander transmission control module is engineered to resolve these exact problems, arriving at your door ready for a straightforward, plug-and-play installation.

An Expert’s Note for the Uplander Owner: The 4-speed automatic transmission in these GM minivans is a workhorse, but its brain is the TCM. When it fails, communication breaks down, leading to the erratic behavior you’re seeing. Simply swapping in a used, non-programmed module is a gamble that rarely pays off. Our VIN programming service is not just a convenience; it’s a critical step that ensures all the unique software parameters for your specific vehicle are correctly loaded. This prevents compatibility issues and ensures the new Uplander transmission control module functions correctly from the moment it’s installed.
Don’t let a faulty computer sideline your family’s vehicle. Installing this replacement Uplander transmission control module is the most effective way to fix your transmission problems for good and get back to driving with confidence.
Frequently Asked Questions
What does a transmission control module do on a Chevy Uplander?
The TCM acts as the computer for your automatic transmission. It collects data from various sensors in the engine and transmission to control shift timing, fluid pressure, and torque converter lockup, ensuring smooth and efficient operation.
Is this module difficult to install?
No, installation is designed to be straightforward for a DIYer with basic tools. On the 2006-2009 Uplander, the TCM is typically located on the LH strut tower. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. The entire job usually takes less than 30 minutes.
Will this TCM 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 underlying issue causing the P0700, it’s always wise to have the specific transmission codes read to confirm the diagnosis. This part is a common fix for issues related to solenoid performance and internal TCM faults.
Do I need to take my van to the dealer after installation?
No. The main benefit of our module is that it comes pre-programmed to your vehicle’s VIN. This means you can install it yourself and it will work immediately, with no need for an additional, costly trip to the dealership for programming.
Is there a core charge for my old part?
There is no core charge. You are not required to send your old, faulty module back to us, which simplifies the repair process for you.
