I was on the highway and i got off at a exit and came to a stop, when I started to go again my truck would barely respond. I floored it and eventualy it got up to 2k RPMs and would drive normal. A minute down the road the O/D light started flashing on and off and the message center read "transmision failure" it was still barely responding from a start but it'd drive normal in the upper RPMS. I drove it home(only 5 miles away) and the Edge gave me the codes P0731 and P0732 and i just looked this up and they are the codes for incorrect gear ratio 1 and 2(I guess first and second gear)

The truck runs fine now, this happened yesterday but what does it mean? Just a couple sensors loose or something? Although I didnt drive it hard or a lot, its running perfect as of right now.

 

Mine acted like that when first gear failed, I wonder if a sensor is bad on it...no clunks or thuds?

 

sounds like it might be stuck in 3rd

 

My Ranger did that right before it gave out all together. Turned out the previous owner loved to dog it.
