Q: Will Not Go In Park.
Answered by Jay
It sounds like you may have broke the shift mechanism trying to get it out of park. Since it's now broken it won't engage anymore. I'd suggest have the system checked (https://www.yourmechanic.com/services/car-is-not-shifting-into-park-inspection) by a certified mechanic, like one from YourMechanic,...

Trusted by thousands of happy car owners



Tom went above and beyond to make me as satisfied as I could be. His communication was excellent. Friendly and professional and best if all, my car is running great and he did it without unnecessary repairs. I would and will highly recommend Tom and Your Mechanic to everyone. Thanks, Rob Miller.



Stephen was very professional and spoke to me in terms that I understood. Although the news about the car was not great, he explained the why's and what it would take to fix it. I will call on him again. Many thanks!



Very impressed with the quality of work. Ned was on time and on budget. There were no surprise extra costs. Ned even helped me out with my other car, even though I didn't have an appointment for the other car. He took care of all of my car problems and he even found me a coupon for an oil change. I will be using this service again.
