The transmission over revs between 3rd and 4th gear. It hesitates then loses power, then slams into the next gear. Once in 10th gear it hesitates when trying to pass other vehicles. When decending hills it quickly jumps to second gear causing the wheels to skip or bounce for a few seconds. When merging onto the highway the hesitation nearly got me rearended. The transmission shop is updating the software and changing the fluid. He said most of these need rebuilt when this happens. Ford told me its a new type of transmission and that I will ‘get use to it’. Repair or replacement is anywhere from $4,000 to $9,000, yet ford keeps selling this defective product. There are no indicator / warning lights.
