I have a 2001 F250 W/7.3 and what is going on is wants this thing gets warm and i am coming to a stop it wont shift back to 1st i have to manualy shift it from this point and i notice the od light is flashing but this dont happen all the time it only does this when the light flashes. I had a friend put it on the comp. and it is saying the out put speed sensor and the tc wont unlock so am i looking at just the speed sensor and all will be fine or is it terminal????
