I have a 93 e350 with a 7.3 diesel in it that seems to shift late and hard at times. It will also shuttle from 3 to 2 and back and fourth at times. Im not sure of model on trans cant find any tags. I know it is metric and code on door is E. Works fine in overdrive and seems to be worse at operating temp. Vehicle was owned by company I work for and I believe it has been rebuilt at least once already. Any comments are apprecated
