So after driving my car for the last 3 weeks I’ve noticed some strange rpm issues in the morning and couldn’t figure out why because the car will run perfectly fine after that. I took it to the dealership to check and told me that they got an error code “P07457F” which means one of the solenoids in the transmission is stuck. I asked them why couldn’t they replace the piece which is around $300 and they told me that these transmissions can’t be rebuilt/repaired only replaced. Which will run me exactly $7021 (parts and labor) So my question is to you guys are they telling the truth or they are trying to get 7 grand out of me instead of fixing a $300 piece?
