Frequently Asked Questions
Is this TCM really plug-and-play?
Yes. We program the module to the VIN you provide during checkout. This ensures it communicates perfectly with your vehicle’s other computers right out of the box, with no need for a trip to the dealer for additional programming.
Do I need special tools for installation?
No special tools are required. Installation typically involves basic hand tools like a socket set and can be completed in under 30 minutes. The module is located in the engine compartment, and its exact position is noted in the fitment list for your convenience.
How do I know for sure that my TCM is the problem?
Common symptoms like erratic shifting, being stuck in limp mode, and specific diagnostic codes like P0700 are strong indicators. While it’s always best to have a professional diagnosis, if your vehicle is experiencing multiple of the listed symptoms, the TCM is a very common point of failure.
Is there a core charge for this part?
No, there is no core charge. You can keep your old part without the hassle or expense of sending it back, making the replacement process even simpler.
What should I do after installing the new module?
After installing the new TCM, we recommend disconnecting the battery for about 15 minutes to reset all vehicle systems. Once reconnected, use a standard OBD2 scan tool to clear any stored trouble codes from the vehicle’s memory to ensure a fresh start.
