The manuals on the IDI's are the Borg Warner T-19 4 speed non overdrive (1:1 4th gear). This is what my truck has, basically a bulletproof trans, I've never heard of them really trully failing on anybody. They came in 1983-1986 trucks. They are really really cheap, like you could probably find one used in good condition for around $400 . Then there was the ZF-5 speed, it is a 5 speed overdrive tranny. Not as strong as the T-19, but has overdrive. They came in 1987-1997 IDI's and powerstrokes, and yes you can use one from a powerstroke, or vis a versa (1987 was a transition year though both the T-19 and ZF-5 speed were offered). A good used one can run $600-1000.
