Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. This is the primary benefit of our product. We program the module to your vehicle’s specific VIN before it ships. It will arrive ready for installation, with no additional programming or setup required.
Where is the TCM located on my Express 2500?
On the 2006-2014 Express and Savana vans, the Transmission Control Module is typically located in the engine compartment on the right-hand (passenger) side. Always disconnect the vehicle’s battery before beginning the replacement.
Is this a difficult part to install myself?
For someone with basic mechanical skills, the installation is very straightforward. It usually involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. The entire process often takes less than 30 minutes. We recommend using a scan tool to clear any stored fault codes after installation.
Will this fix a P0700 trouble code?
A P0700 code is a general transmission fault request from the TCM to the Engine Control Module (ECM) to turn on the check engine light. While this module can resolve the underlying issue causing the P0700, it’s important to diagnose any other codes that are present. A faulty TCM is a very common cause for this code and related shifting problems.
Is there a core charge for my old part?
No, there is no core charge required for this module. You can keep or dispose of your old part without the hassle of returning it, making the process simpler and faster.
