This saves you hours of diagnostic headaches and the potential cost of a tow to the dealership, making it the smartest choice for both professional technicians and DIY installers.
Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. This module is delivered to you fully pre-programmed to your vehicle’s specific VIN. It is ready for installation right out of the box, with no additional programming or dealer visit required.
What tools are needed for installation?
Installation typically requires only basic hand tools to access and unbolt the module. We highly recommend disconnecting the vehicle’s battery before starting. After installation, a basic OBD2 scan tool is useful for clearing any stored diagnostic trouble codes.
Is there a core charge for my old part?
No, there is absolutely no core charge. You can keep, recycle, or dispose of your old module at your convenience without any extra fees or hassle.
Will this part fix a P0700 trouble code?
A P0700 code is a general fault code indicating that the TCM has detected a problem. While this Programmed T42 Transmission Control Module often resolves the root cause that triggers a P0700, it’s always best to diagnose any other specific codes that are present (e.g., solenoid codes) to confirm the TCM is the point of failure.
Where is the T42 TCM located on my vehicle?
The location varies by model. Common locations include the engine compartment on the RH or LH side, next to the battery, under the air cleaner box, or on the LH strut tower. Your vehicle’s service manual will show the exact location.
