Another Salesman lied

dbbls ,on the transmission I have one of the first 2001 F250s. It was built in october 2000. So it had the mechanical diode clutch in it . That they got rid of after 6 months of warranty transmission repairs. I had a cabover camper on it till 2006. So I was not worried about the transmission with it. Their was not enough weight. But with the 5th wheel their was. I took the truck to a transmission guy I have known for years. I had him remove the transmission and put the sprag one way clutch back in to replace the diode clutch. I also had a 3 disc heavy duty torque convertor installed.Plus I had a shift kit installed with the instructions that I did not want to have to wear a neck brace when it shifted. I have added a couple of transmission coolers and one has a fan that will turn on if in town running less then 40mph and the transmission oil temperature is wanting to rise. I have my own transmission gauge and 3 sending units. One reads the oil coming out of the torque convertor, one reads the oil from the cooler to back to the transmission. And one reads the oil temperature in the pan. So I have not had a transmission problem due to pulling my 5th wheel.
