Your Work Van is Down. Let’s Get it Back on the Road.
As a shop owner, I know that when a workhorse like a 2006-2014 Chevrolet Express 3500 is out of commission, every minute costs money. Often, the culprit for sudden, frustrating transmission issues isn’t the transmission itself, but its electronic brain: the Transmission Control Module (TCM). If your van is banging into gear, refusing to shift, or stuck in limp mode, you’re likely dealing with a failed TCM. This isn’t just an annoyance; it’s a critical failure that sidelines your business.
This T42 TCM, part number 24234503, is the definitive solution. We pre-program it to your van’s specific VIN, making it a true plug-and-play replacement. You can get your vehicle running smoothly again without an expensive tow to the dealership and without waiting for them to perform the programming. This is the fast, reliable fix that gets you back to work.
Is Your Express 3500 Showing These Symptoms?
A failing TCM will make its presence known. Over my 20+ years turning wrenches, I’ve seen these modules cause a predictable set of problems. See if any of these sound familiar:
- โ The van slams into gear, especially when shifting from Park to Drive or Reverse.
- โ It’s stuck in one gear (usually 2nd or 3rd), a condition known as “limp mode.”
- โ The Check Engine Light is on, with transmission-related codes like P0700, P0750, or other solenoid faults.
- โ Delayed or no shifting, causing the engine to rev high without changing gears.
- โ A sudden, noticeable drop in fuel economy.
- โ The transmission feels like it’s slipping, but the fluid level and condition are fine.
Expert Pro Tip: Check Before You Replace
On the Express and Savana vans, the TCM is located in the right-hand (passenger side) engine compartment. Before you condemn the module, take a moment to inspect the large electrical connectors. I’ve seen cases where road salt and moisture cause significant corrosion on the pins, leading to the same symptoms as a failed module. A quick cleaning with a contact cleaner and a small brush can sometimes solve the problem. If the pins are clean and the problems persist, the module itself is the next logical step.

- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the TCM: On your Express 3500, find the module in the engine compartment on the passenger side.
