Expert Technician’s Insight
From a technician’s perspective, the biggest hurdle in replacing a modern TCM isn’t the physical install—it’s the programming. An improperly programmed module in a workhorse like the Express 3500 can lead to incorrect shift points under load, poor fuel economy, and even premature transmission wear. That’s why we handle the VIN programming before it ships. We ensure the module communicates perfectly with your van’s specific powertrain, so you get OEM-level performance from the moment you plug it in. It’s not just a part; it’s a complete solution designed to minimize your downtime and protect your investment.
Frequently Asked Questions
What does VIN programming mean for my Express van?
VIN programming means we load your vehicle’s unique Vehicle Identification Number and its associated software into the module before we ship it. This ensures the TCM works perfectly with your van’s engine, transmission, and other systems right out of the box, just like the original part from the factory.
Is this a difficult part to install myself?
For someone with basic mechanical skills, this is a very straightforward installation. The TCM is typically located in the engine compartment on the RH side. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. Most installations take under 30 minutes.
Do I need to send my old TCM back?
No. There is no core charge for this part. You can keep or dispose of your old module, saving you the time and hassle of a return shipment.
Will this 2006-2014 Express 3500 TCM 24243901 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 of a P0700, it’s essential to have the vehicle scanned for other specific codes (e.g., P0751, P0756) to confirm the TCM is the issue. In most cases of internal TCM failure, replacement is the correct fix.
How do I provide my VIN for programming?
After you place your order, you will be prompted to provide your vehicle’s 17-digit VIN. Please ensure it is accurate, as this is critical for correct programming.
Is this compatible with other GM vehicles besides the Express van?
Yes, this T42 TCM is compatible with a wide array of 2006-2014 GM vehicles, including the Silverado, Tahoe, Sierra, Yukon, Impala, and many others equipped with 4-speed automatic transmissions like the 4L60E, 4L65E, and 4L70E. Please check the compatibility list to confirm your specific model.
