Mark, thanks for all your help, the truck has 28,000 miles, so I had to pay the big bucks. I will be towing a 22'' enclosed car hauler, when loaded it should weigh around 8,000 lbs. I will be pulling with the bumper hitch. I will be getting the transmission serviced next week. I know its hard to predict but have you seen the 2001 trannys go over 100k before they break? I hope and pray I have some more miles left in this tranny. It seems to shift fine with no issues. What kind of symptoms does the truck have when the diode fails?
Thanks
