Frequently Asked Questions
What does a VIN-programmed TCM actually do?
VIN programming loads your vehicle’s specific operational software onto the module. This ensures it communicates perfectly with the engine computer and other systems, controlling shift points, torque, and other parameters exactly as the manufacturer intended for your Express 3500’s configuration. This is the key to a true plug-and-play repair.
Is this part difficult to install on my Express van?
Installation is straightforward for someone with basic mechanical skills. On most 2006-2014 Savana and 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. The entire job can usually be completed in under 30 minutes.
Will this fix a P0700 diagnostic 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 (like a failed internal driver that triggers other codes), it’s essential to diagnose any other potential issues. However, if the TCM itself is faulty, replacing it with this part is the correct solution.
Do I need to send my old part back?
No. We do not require you to return your old module. There is no core charge associated with this part, which simplifies the process and saves you the hassle of return shipping.
