2018 Ford Expedition Transmission 10R80 Issue Overheated and Oil Leak
Looking to see if anyone else has had a simular issue with Transmission
2018 XLT Max
67,000 Miles
10-speed (10R80)
Last August 2025 had the CDF Drum replaced with no known issues till now (August 2026)
Last Friday driving on the interstate with cruse set at 75 mph and after 1 hour of driving started to feel a jolted/hasitating as if it were down shifting or losing power/speed, then suddenly I was able to accelerate then it happened two or three more times. At first I thought it was my cruse control adjusting speed behind another vehicle till I realized something was really wrong.
Exited off and stopped. Noticed the temp was 237 degrees and smelled buring oil. Noticed covered the whole back of my vehicle and full of oil underneath. Was told it was safe to drive back after letting it cool down. Drove back 1 hour straight to the dealer. Temp on the drive back ranged from 205-208 on the intersate till Idrove into town and got to 212. Dealer looked underneath and confirmed it was transmission oil and it was really bad. Left it there over the weekend and Monday got a call back that they did not find anything wrong with it, internal parts all looked good and no damages from overheating, no codes and still had the right amout of oil in it. They tested everything and never got it to overheat. I don't understand how I lost so much oil and still has the right amount. The only thing the service adviser mentioned somethng about a Vort and venting the oil. Not sure exactly what she meant unless I misunderstood her.
I drove it around town today with speeds around 45-50 mph and when I got home the temp was around 217. I am not sure what the average temp is town/highway.
Here is where I am, I need to take an out of town 3 hour trip tomorrow and concerned if I should be taking this chance and getting stranded. I have a tow package on my insurance, but only to the nearest dealer and don't want it stuck out of town.
Hopefully someone can share any experience with this. Thanks and sorry for the long post.
