An Expert’s Note on VIN Programming
“We see it all the time: a customer buys a generic, non-programmed module online, installs it, and the problems get worse. That’s because the TCM is the ‘brain’ of your transmission; it needs to speak the exact same language as your van’s main computer (ECU). Our VIN programming process ensures they’re perfectly synced from the moment of installation. It’s the critical step that separates a quick, permanent fix from a frustrating, recurring problem. This isn’t just a part; it’s a complete solution for your Express 1500 transmission control module.”
Whether you’re a fleet manager minimizing vehicle downtime or a DIYer determined to fix your van right the first time, this module is the smartest choice. Don’t let a faulty TCM sideline your vehicle any longer. Restore its performance and reliability with this ready-to-install Express 1500 transmission control module.
Frequently Asked Questions
Is this TCM truly ‘plug-and-play’?
Yes. We program the module using the VIN you provide during checkout. This ensures it has the correct software and calibration for your specific vehicle, allowing for a straightforward installation without any need for further programming at a dealership.
Will this 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 root cause (such as internal TCM failure), it’s always wise to have the specific secondary codes read by a scanner to confirm the diagnosis. In many cases where the TCM itself is faulty, this part is the correct solution.
Where is the TCM located on a Chevy Express van?
On most 2006-2014 Chevrolet Express vans, the Transmission Control Module is located in the engine compartment on the right-hand (passenger) side. Always disconnect the vehicle’s battery before beginning the replacement process.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep or dispose of your old module, saving you the hassle and expense of return shipping.
How do I ensure this is the right part for my van?
This module fits 2006-2014 Chevrolet Express 1500, 2500, and 3500 vans.

Providing your VIN at checkout is the final step to guarantee perfect compatibility.
