The 4.3 trans will bolt. The 4L60 and 700R4 are practically the same trans, other than a few electronic controls. The only concern using the 4.3 trans is the lack of holding power from not using as many clutches, otherwise, they would work ok. The other problem is the converter stall speed. Diesels stall at lower rpm's than gassers, but if you don't mind a little wind, it would work. Gasser tend to stall at about 1200, I don't know the spec of the diesel stall though.

The other workhorse: 92 F350 2wd crew cab, 92 6BT Cummins, NV4500 and GV overdrive unit, 4.10 rear axle
