Months back the transmission quit transmitting. The Grandson loaded it up and took it to a transmission shop close to Toledo. The Fellow just started on it last week. I just came back from there and the overdrive shaft sheared off. He has ordered three different shafts and none would fit. This shaft runs on a one inch ID bearing and all replacement shafts are for a 1 1/8" ID bearing. He is supposed to be getting a complete kit today with the bearing support and all. He said he has been doing transmissions for 20 years and never seen this part. He said his parts supplier told him it must have been an after market part put in when it was rebuilt before. This will be the third rebuild for me. The will not work on it until next week again. Old ugly has all new brakes, a rebuilt front end with six new tires. Now a rebuilt transmission with what he is calling a dorF update kit which is heaver than the original. 130,000 on the 1994 7.3 so it should take me into eternity.
