Frequently Asked Questions
What is a Transmission Control Module (TCM)?
The TCM is a computer that acts as the ‘brain’ of your automatic transmission. It collects data from various sensors in the vehicle and uses that information to control when the transmission shifts gears, ensuring optimal performance, fuel efficiency, and smooth operation.
How does the VIN programming process work?
During checkout, you provide us with your vehicle’s 17-digit VIN. Our technicians then use specialized equipment to load the exact factory software and calibration files for your specific vehicle onto the T42 module. When you receive it, it’s ready to install and function perfectly without any additional steps.
Is this part difficult to install?
For most of the compatible vehicles, the TCM is located in an accessible spot in the engine compartment. Installation typically takes under 30 minutes and requires basic hand tools. We always recommend disconnecting the battery before starting the replacement to ensure the vehicle’s computer systems reset properly.
Will this fix my specific error code, like P0700?
A P0700 code is a general fault code indicating the TCM has detected a problem. This VIN Programmed T42 Transmission Control Module is the direct solution for failures within the module itself, which is a very common cause for this and other related transmission codes. After installation, be sure to clear any old codes with a scan tool.
Do I need to send my old part back?
No, there is absolutely no core charge or requirement to return your old module. This saves you the time, cost, and hassle of shipping back the old part.
