Shifting Problem
2015 F-250 Super Duty, 6.2 L Gas with 6r140 Transmission
I have 13 K miles on my truck. While pulling my travel trailer up a hill the transmission kicks down thru the gears, which is fine, but as I crest the hill and in 2nd gear, the engine begins to rev up and the speed increases, the transmission will not automatically go into3rd gear. I have tried to let up on the gas pedal, but it remains stuck in 2nd gear. I have to shift to "Manual" and then put it in 3rd gear. Then it shifts up as it should. I have tried with the transmission in "TOW' and not in "TOW". I have even tried it in “Cruise Control”.
Ford dealership ran tests but could find no problem. However it was road tested without the trailer.
Any thought? Thanks

in TOW mode.. the computer can hold a given gear a very long time..
I bet ,, the hill may have been less steep as you went up.. so computer still "Sees" it going up hill
and there is always the HEAD WINDS..
you may not like it .. but it does know whats it is doing.
and you have a "report" at the dealer in case there is a problem in the future.

Shifting Problem
Transmission fluid is fine. This problem happens almost every time I'm pulling the travel trailer up a hill and it gets into 2nd gear.
I think my next move is to plug in my Lemur Bluedriver OBD2 Scanner and monitor it while pulling the trailer.
My question is, does an OBD2 monitor transmission operation?
