I just bought a 2017 Explorer XLT 2.3l n June of this year. I have about 9000 miles on it and transmission started making a whirring noise similar to straight cut gear noise. Then vehicle would shift out of gear and then engage all of a sudden, feels like putting it into neutral and slamming it into drive while revved up. Took it to the dealer and they confirmed that the noise was not normal so they tore own the trans and they said had burnt clutches. They also found the case was seeping oil from a fill plug so they swapped out the case with a new one. Trans was reinstalled and when they test drove it it skipped gears, they removed trans and rebuilt again with more components like sun gear and tested valvebody and reinstalled. Test drove it and shifted fine until it got to a stop where it shifted into 5th gear and was stuck in 5th gear. Ford sent a reprogram for the truck and got that done and was no fix at all. Now they are replacing the valve body but will need to be ordered. The truck has been at the dealer for about 32 days. I was given a rental, A Focus... which is not comparable at all to the Explorer. I spoke to Ford Customer service and they opened a case for buy back after I told them the attempted repairs and time it has been at the dealer.They also said there was an option to upgrade. Anyone have transmission issues, or have gone thru a buy backprogram ?
