Had a problem with hard shifting and up and down shifting out of the blue while driving on interstate. Ford recommended a trans service. Had it done 3 days before trip to NC. For Christmas. On our way home the truck started a hard back and forth up and down shifting. We pulled off highway and found trans fluid everywhere. I could not find a leak. Called and got a tow the next morning to a ford dealer in Georgia. Found trans was overfilled. Made it home but trans is still shifting hard and gs into neutral while driving down the road. You need to recall all these 10 speed trans. I was quoted 7,000 dollars for an overhaul and told I may still have the same issue sooner than later.
