Frequently Asked Questions
What does a VIN-programmed TCM mean for me?
It means the module arrives ready for installation with no extra steps. We load your vehicle’s specific software onto the TCM before shipping, so it communicates perfectly with your van’s engine and other systems right away, just like the original part from the factory.
Is this a difficult part to install myself?
For most individuals with basic mechanical skills, this is a straightforward installation. It’s typically located in the engine bay, secured by a few bolts and electrical connectors. The entire process usually takes less than 30 minutes. Always remember to disconnect the battery before you begin.
Will this TCM fix my P0700 trouble code?
A P0700 code is a general transmission fault request from the TCM. While this module often resolves the root cause that triggers a P0700 (like a solenoid circuit fault), it’s crucial to diagnose any other specific codes that are present. In many cases, a faulty TCM is the primary issue.
Do I need to return my old TCM?
No, there is no core charge for this part. You can keep your old module, which saves you the time and hassle of packaging and shipping it back.
How do I provide my VIN for programming?
After placing your order, you will be prompted to provide your 17-digit Vehicle Identification Number (VIN). Our technicians use this to ensure the module is programmed with the exact software for your Savana 3500.
