Expert Insight: The Cost of Downtime
We recently worked with a plumbing contractor whose 2011 Express 2500 was stuck in third gear. Every day the van was down meant rescheduling jobs and losing revenue. The dealership quoted him a high price and a multi-day wait for a new module and programming. We sent him a pre-programmed 2006-2014 Express 2500 T42 TCM overnight. He installed it himself in under 30 minutes in his own garage and had his van back on the road for a job the very next morning. This isn’t just a part; it’s a tool to keep your business moving forward.
Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM is the electronic brain of your automatic transmission. It uses data from various sensors on the engine and transmission to control shift points, torque converter lockup, and line pressure, ensuring smooth and efficient operation.
Why is VIN programming so important for this part?
VIN programming loads your vehicle’s specific software and calibrations onto the TCM. Without it, the module won’t communicate correctly with your van’s other computers, leading to improper shifting or the vehicle not starting at all. Our pre-programming makes this a true plug-and-play part.
Is this module difficult to install?
No, installation is straightforward for someone with basic mechanical skills. On most Express vans, the TCM is located in the engine compartment on the right-hand side. The process typically involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It can usually be done in under 30 minutes.
My original part number is different. Will this still work?
Yes. This T42 TCM is a direct replacement for numerous GM service numbers, including 24252114, 24234503, and 24234274. As long as your vehicle is listed in the compatibility chart, this programmed module is the correct fit.
Do I need to send my old part back?
No, there is no core charge for this 2006-2014 Express 2500 T42 TCM. You can keep your old part, which saves you the time and hassle of return shipping.
