Restore Smooth, Reliable Shifting to Your Chevrolet Uplander
Is your Chevrolet Uplander’s transmission acting up, causing harsh shifts, delayed gear engagement, and making every family trip a source of worry? A faulty Transmission Control Module (TCM) is often the culprit behind these frustrating and potentially unsafe driving conditions. This OEM-quality GM T42 TCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a seamless, plug-and-play installation that gets your family minivan back on the road with performance you can trust.
Common Symptoms & Your Solution
If you’re experiencing any of the following issues, a failing TCM is the likely cause. This module is engineered to resolve these problems directly:
- Erratic or Harsh Shifting: Unpredictable lurching or banging when the transmission changes gears.
- Vehicle Stuck in Limp Mode: The transmission won’t shift out of a single gear (often 2nd or 3rd) as a protective measure.
- Check Engine & Transmission Warning Lights: Often accompanied by diagnostic trouble codes (DTCs) like P0700, P0750, or other solenoid-related faults.
- Delayed Engagement: A noticeable pause when shifting from Park into Drive or Reverse.
- Poor Fuel Economy: Inefficient shifting forces the engine to work harder, consuming more fuel.
Installing this pre-programmed 2006-2009 Uplander transmission control module corrects the faulty logic that causes these symptoms, restoring crisp, accurate shifting and clearing persistent error codes.

From the Technician’s Bench: The Critical Role of VIN Programming
We often see customers consider using a generic or junkyard TCM to save a few dollars. This is a critical mistake. A transmission module isn’t just a simple computer; it’s tailored with specific software for your vehicle’s engine size, axle ratio, and tire size. Installing a non-programmed or incorrectly programmed unit can lead to even worse shifting, internal transmission damage, and a cascade of new error codes. Our VIN programming service ensures this 2006-2009 Uplander transmission control module communicates flawlessly with your van’s other computers, just as the original did from the factory.
Frequently Asked Questions
What does a Transmission Control Module do on my Uplander?
The TCM acts as the brain for your automatic transmission. It receives data from various sensors on the engine and vehicle, and uses this information to control exactly when and how the transmission shifts gears, ensuring optimal performance, fuel efficiency, and smoothness.
Is this module difficult to install?
For the Chevrolet Uplander, the TCM is typically located on the LH strut tower, making it reasonably accessible. With basic hand tools, most DIYers can complete the installation in under 30 minutes. Simply disconnect the battery, unplug the old module’s electrical connectors, unbolt it, and install the new one in its place.
Do I need to take my van to a dealer after installation?
No. Because we pre-program the module to your specific VIN, no further dealership visits or programming are required. It is a true plug-and-play solution. We do recommend using a basic scan tool to clear any old fault codes from the vehicle’s memory after installation.
How do I know this is the correct part for my vehicle?
This module, part number 24240400, is the specified fit for the 2006-2009 model years. When you place your order, you will provide your vehicle’s VIN, and we will confirm compatibility and program the unit accordingly, guaranteeing a perfect match for your specific 2006-2009 Uplander transmission control module requirements.
What happens if I don’t replace a failing TCM?
Continuing to drive with a faulty TCM can lead to more severe problems. Poor shifting can cause excessive wear and tear on internal transmission components like clutches and bands, potentially leading to a complete transmission failure that is far more expensive to repair.
