Ok, 2001 Ford F250 with the 7.3 engine. 363,000 miles.
I knew something was going to get me and it turned out to be the tranny. Theses trucks are notorious for transmission problems.
The question is, how much, on average, will a transmission repair cost? The truck is only worth about $6000. Am I totalled?
You could always get a salvage, but that's a crap shoot for transmissions. It depends on whether you're a reasonable mechanic, though.
Manual transmissions usually aren't expensive to rebuild, but automatics will be a few thousand--and that's you taking it out and taking it to the shop.
I don't know about self rebuilding, automatic transmissions have intricate valve bodies with balls and springs, it gets hairy. Good luck.
