I have a F-250 2012 super duty free cab. I had problem in the past but they were covered under warranty. Now the problem I am having now only happens when it rains. Something must be getting wet and then the transmission doesn't want to shift. Numbers come up on the dash like it's in manual mode. Then I try to get it out of that mode. Sometimes I have to manually shift until it stops raining. The transmission shifts fine on days it don't rain. Does anybody have an idea what the problem is? Or did anybody have this same problem?
