How do i reset my tcm

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. I do not know what you mean by "reset my tcm" - the transmission control module of the vehicle does its job but doesn't have a way to "reboot" or restart. Also, I do not know which transmission your vehicle is equipped with. That would be helpful information to learn. If you have slipping and no shifting - there is most likely an internal transmission mechanical concern. A diagnostic test using a diagnostic tool that can monitor transmission data going in and coming out would be most helpful too learn more about what is happening. Seek guidance at a locals shop near you. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
