Ok i've read all kind of posts with limping the trani. This one has me baffled I was on the way home trying to out-run a thunderstorm. I was on loose gravel I turned the corner and got on the pedal a little mabe 1/3 of the way down went through all the gears then up-shifted to 4 th and stayed in 4 th. CEL light was on and shut it off and turned it back on and no CEL until I shift into gear. Then light is back on and it shifts normal. I have "hit the throttle" a few times a lot harder than that and never had any trouble. Is it possoble that with the loose gravel that the alli got confused???? Any input would be great.
