Is Your Work Van Sidelined by Transmission Problems?
For a hard-working vehicle like the Chevrolet Express 3500, downtime isn’t just an inconvenienceโit’s lost income. When your transmission starts acting up, the culprit is often its electronic brain: the Transmission Control Module (TCM). In my 20+ years as a technician, I’ve seen firsthand how a failing TCM can bring a reliable workhorse to a grinding halt with symptoms that seem catastrophic but are often solved with this single component.
This T42 TCM, part number 24235753, is the definitive solution for your 2006-2014 Express 3500, arriving expertly programmed to your van’s specific VIN. This means no trips to the dealer for expensive programmingโit’s a true plug-and-play fix to get you back on the job fast.
Diagnosing a Faulty TCM: Common Symptoms I See in the Shop
If your Express van is experiencing any of the following, a failing TCM is the likely cause:
- โ Harsh, banging shifts or delayed gear engagement.
- โ The vehicle is stuck in “limp mode,” usually in 2nd or 3rd gear.
- โ Check Engine Light or Transmission Warning Light is on with codes like P0700, P0750, or other solenoid-related faults.
- โ Complete failure to upshift or downshift, leading to poor acceleration and fuel economy.
- โ Intermittent loss of communication with the module, causing unpredictable behavior.
From the Shop Floor: A Real-World Scenario
“A customer’s 2011 Express 3500 came in last week with these exact symptomsโit was stuck in 3rd gear, and the scanner was showing multiple solenoid circuit codes. The owner was convinced he needed a full transmission rebuild. However, my experience with these T42 modules, especially in work vans that see heavy use, pointed me to the TCM first. Before condemning the whole transmission, we installed one of our VIN-programmed modules. In less than 30 minutes, all the codes were gone, the van was shifting perfectly, and the customer was back on the road, saving thousands over a transmission replacement.”
Plug-and-Play Installation: Get Back to Work in Under 30 Minutes
Replacing the 2006-2014 Express 3500 Transmission Control Module is a straightforward job you can do with basic tools. No complex wiring or dealer-level equipment is needed.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system’s adaptive memory.
- Locate the Module: On the Express and Savana vans, the TCM is typically found in the engine compartment on the right-hand (passenger) side.
- Disconnect and Remove: Carefully unclip the electrical connectors. Be gentle to avoid damaging the pins or clips. Then, unbolt the old module from its mounting bracket.
- Install the New TCM: Bolt the new, pre-programmed module into place and securely reconnect the electrical harnesses. You should hear a distinct click as they lock in.
- Final Steps: Reconnect the battery terminal. Start the vehicle and use a basic OBD2 scan tool to clear any stored diagnostic trouble codes (DTCs). Take the van for a test drive to confirm smooth shifting.
