I own a 2018 Expedition with the Heavy Duty Tow package. It has 76k miles on it. We bought it in February 2018 and have never towed with it until yesterday. I bought a 3200 lb. horse trailer and towed it home 1.5 hours. On the interstate on a very slight uphill grade in Ohio the transmission temps rose until they hit 246 F. I was going about 65 mph. The temps would settle into the 220s or so on level ground and 45 to 55 mph. I did not think this was normal. When I finally got home I noticed a puddle of ATF on the driveway. I let it cool and detached the trailer and parked the vehicle in my garage. I found another smaller puddle this morning. Anybody know what is going on?
