A Mechanic’s Note: The VIN Programming Advantage
As a technician, I know that for a work vehicle like an Express van, downtime is lost income. The biggest advantage here isn’t just the quality part—it’s the pre-programming.

You install it, connect the battery, clear any old codes, and the vehicle is back in service. It’s the fastest, most efficient way to solve the problem and get back to making money.
This module is the ideal fix for a huge range of GM vehicles, from a work-ready Savana van to a family-hauling Tahoe. By ordering this pre-programmed 2006-2014 Express 2500 T42 TCM, you are choosing a reliable, cost-effective repair that gets the job done right the first time.
Frequently Asked Questions
What does a VIN-programmed TCM mean?
It means we flash the module with your vehicle’s unique Vehicle Identification Number (VIN) before shipping it. This ensures the TCM has the correct software and calibration for your specific engine, transmission, and options, allowing it to work perfectly right out of the box without any additional programming.
Do I need to take this part to a dealer after installation?
No. Because the module is pre-programmed to your VIN, you do not need to visit a dealership or repair shop for programming. This is a true plug-and-play solution that saves you time and money.
Where is the TCM located on my vehicle?
Location varies by model. On many GM trucks and vans like the Express, it’s in the engine compartment on the right-hand side. On other models, it can be near the battery, on the LH strut tower, or under the air cleaner box. Please consult a repair manual for your specific vehicle’s location.
Will this fix a P0700 trouble code?
A P0700 code is a general code indicating the TCM has detected a fault. Often, replacing a faulty TCM will resolve the P0700 and any related specific codes (like for shift solenoids). However, you should always ensure the transmission’s internal components and wiring are in good condition.
Is a core charge required for this part?
No, there is no core charge for this module. You can keep your old part without the hassle of returning it.
How do I provide my VIN?
You will be prompted to enter your vehicle’s 17-digit VIN during the checkout process. Please double-check it for accuracy to ensure correct programming.
