Frequently Asked Questions
What does “VIN Programmed” actually mean for me?
It means the module arrives at your door completely ready to be installed. We use your vehicle’s unique 17-digit Vehicle Identification Number (VIN) to load the correct factory software and calibrations onto the module before we ship it. This eliminates the need for expensive tools or a trip to the dealership for programming, making the installation truly plug-and-play.
Is this part difficult to install myself?
For most models, the installation is straightforward for someone with basic mechanical skills and can often be completed in under 30 minutes. The TCM is typically located in the engine bay. The only tools usually required are basic hand tools to disconnect the battery and unbolt the module. Always disconnect the battery before starting work.
Will this fix my specific check engine light codes, like P0700?
Yes, this VIN Programmed T42 Transmission Control Module is designed to resolve a host of transmission-related Diagnostic Trouble Codes (DTCs), including the general fault code P0700 and various solenoid-specific codes. If your diagnostics point to a faulty TCM, this part is the correct fix.
Do I need to send my old TCM back?
No, there is no core charge or requirement to return your old part. You can dispose of it at your convenience, saving you the time and hassle of shipping a core back.
How do I find my vehicle’s VIN?
Your VIN can be found in several places: on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
