7.3 turbo diesel box truck

I have a 1997 Ford e350. Its got the 7.3 in it. I ran her all tax season now it’s just sitting. She’s a strong runner been out to Madison green bay wis dells at 85+ mph. Shifts good when I would deliver in the city. If I went on freeway for a while and got off it would have trouble shifting out of first. You have to let off on gas to shift out 1st then it would be fine. Its also got an exhaust and oil leak. Exhaust leak isn’t horrible it right off the manifold. Block heater works. Its only got 138xxx miles on it. Would also trade for a nice pick up. Price is obo
