Sep 3, 2025Transmission & drivetrain
Less than 4000 miles- first transmission failed while pulling a large trailer- ford replaced the transmission and the new transmission, only 200 miles later did the same thing when pulling a trailer, up hill. It throws the transmission into 10th gear and you loose all power, Check engine light comes on and it slams back into 4th gear. Will not shift in or out of 4th. We were almost in a head on collision pulling a trailer because it did it while passing a semi and we had no power. Two transmissions this low of mileage seems like it must be a batch of faulty transmissions that need to be recalled asap.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your
pre-purchase inspection list. Back to the
