Get Your Chevrolet Uplander Shifting Smoothly Again
If your 2006-2009 Chevrolet Uplander is suffering from harsh shifting, getting stuck in gear, or has an illuminated check engine light, a failing Transmission Control Module (TCM) is the most likely culprit. As the electronic brain of your automatic transmission, a faulty TCM can make your family minivan feel unreliable and unsafe. This direct-fit T42 TCM, part number 24255280, is the definitive solution, arriving expertly VIN-programmed for your specific vehicle. This eliminates the need for expensive dealership visits for programming—making it a true plug-and-play fix.
A Technician’s Notebook
I remember a 2008 Uplander that came into the shop stuck in 3rd gear—a classic ‘limp mode’ case. The owner was worried about a costly transmission rebuild. A quick scan showed a P0700 (Transmission Control System Malfunction) code. From experience, I knew these T42 modules were a common failure point. Instead of a multi-thousand dollar repair, we installed one of these pre-programmed units. In less than an hour, the codes were cleared, the van was shifting perfectly, and the customer drove away relieved. This is often a simple electronic fix, not a catastrophic mechanical failure.
Is Your Uplander’s Transmission Brain Failing?
A failing TCM can manifest in several ways. If you’re experiencing any of the following, it’s time to consider a replacement. Addressing these symptoms early can prevent further damage to your transmission’s mechanical components.
- ✔ Harsh, erratic, or delayed gear shifts that make driving uncomfortable.
- ✔ Vehicle is stuck in a single gear (limp mode) and won’t shift up or down.
- ✔ Check Engine Light or Transmission Warning Light is on, with Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid-related faults.
- ✔ A sudden drop in fuel economy as the transmission operates inefficiently.
- ✔ The transmission feels like it’s slipping between gears or fails to engage properly from a stop.
- ✔ Complete loss of communication with the module, leading to a no-start or no-shift condition.
DIY-Friendly Installation in Under 30 Minutes
You don’t need to be a professional mechanic to install this part. With basic hand tools, you can get your Uplander back to factory performance right in your own driveway. Our VIN programming makes this a simple component swap.
- 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 2006-2009 Uplander, the TCM is conveniently located on the driver’s side of the engine bay, mounted to the LH strut tower.
- Swap the Part: Carefully disconnect the electrical connectors from the old module. Unbolt it from its mounting bracket and set it aside. Bolt the new module in its place and securely reconnect the wiring harnesses.
- Final Steps: Reconnect the battery terminal. Start the vehicle and allow it to idle for a few minutes. While the module is plug-and-play, it’s good practice to use a basic OBD2 scan tool to confirm no old codes are stored in the system.

Why is VIN programming so important for this part?
Why is VIN programming so important for this part?
VIN programming loads your Uplander’s specific software and shift strategies onto the module before it ships. This ensures it communicates perfectly with your vehicle’s engine computer and other systems right out of the box, avoiding the need for expensive tools or a trip to the dealership for calibration.
Will this fix my Uplander being stuck in ‘limp mode’?
Yes, in the vast majority of cases. A failing TCM is the number one cause of a GM vehicle entering transmission limp mode (typically stuck in 2nd or 3rd gear). Replacing it with this pre-programmed unit is the direct fix for that issue.
How difficult is the installation for a DIYer?
This is a very straightforward installation. On your Uplander, the TCM is easily accessible on the driver’s side strut tower. It involves unplugging connectors and removing a few bolts. Most people with basic tools can complete the job in under 30 minutes.
