I have an 02 Chevy Tahoe just had someone do my transmission n now it’s all messed up !!! Now it don’t engage in park ,you could hear it shift back in forth under the truck when pulling off n stopping 🤦🏼‍♀️, it makes a really loud grinding noise in reverse n don’t move in reverse at all but it will drive fine

 

Take it back to the A$$-****'s who did the job and make them do the work properly this time. They gave you some kind of warranty, correct? If not, it's time to call the BBB and take them to small claims court. Don't forget to add their facility to YELP with a bad review, also. Lots of rip-offs in the businesses in the auto repair sector. I am thankful I have a great independent repair shop for things that I need a hoist for.I am getting to that age where I know I won't be able to do what I once could do easily.
