In the market for a diesel truck. I was looking for a 99-02 superduty with the 7.3. Most of them have over 100,000 miles which from what i have read is nothing for these motors, but my concern was the transmission and other parts. How are the autos in these trucks? I really would like to get a manual but they seem like they are hard to find. Anything else you would be concerned about in these years?
