Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. We pre-program this module to your vehicle’s exact VIN before it ships. It will arrive ready for a plug-and-play installation, saving you the time and expense of a dealership visit.
Where is the TCM located on my 2006-2014 Savana 2500?
On the Savana and Express vans, the Transmission Control Module is typically located in the engine compartment on the right-hand (passenger) side.
Is installation difficult? Can I do it myself?
For someone with basic mechanical skills, the installation is straightforward. It usually involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and installing the new one. The entire process typically takes less than 30 minutes.
Will this fix a P0700 trouble code?
A P0700 code is a general transmission fault code, indicating that the TCM has detected a problem. While a faulty TCM is a very common cause, you should always diagnose any other codes that are present. However, replacing a known-bad 2006-2014 Savana 2500 transmission control module is often the definitive fix for this and related codes.
What happens if I don’t replace a failing TCM?
Ignoring a failing TCM can lead to more severe transmission damage. Continued harsh shifting and slipping can cause excessive wear on internal components like clutches and bands, potentially leading to a complete transmission failure that is far more expensive to repair.
