Vehicle has no gears and will not move. Was able to pull into parking lot. Transmission has acted jerky and slipped gears since I bought it.
While driving car shifted from 2nd to neutral. Engine rpms went up but no power was transfered to tires. Had to put car into park and then back into drive to regain power transfer to tires. Luckily no one was injuried. Took car to local mechanic. Diagnostic came up with no error messages. Service tech took it for a brief test drive and noticed issue with transmission. Recommended transferring to dealership where truck was purchased. To date all maintenance has been performed by dealership. Followed their 'recommended' maintenance schedule.
I was driving and all of a sudden I lost acceleration in the middle of an intersection. My truck had no gears and gave me zero indication there was an issue. I then was told Ford has a newly designed part that fixes the issue and I would have to pay $7500. How does a manufacturer knowingly sell such a dangerous product, and not have a recall for that product after updating a faulty design?
Transmission slipping and hard down shift and hesitation from 2nd to first , has had rear wheel lock up while moving , dealer is ignoring my issues . Thanks
