Mechanically yes the bolts all fit, but the 4L60E needs a computer program to run, the 700R4 does not. GM sells a computer to make 4L60s go in vehicles without the capability to control the computer.

I don't think the computers will swap, this is a leap from OBD-1 to OBD-2 with completely different injection (TBI to CPI) with different data generators, sensors, resolvers etc.

I don't see this as simple or cheap.

An alternative could be to use the 98's short block with the 93's heads and injection. This ought to go without any problems. But I'm speaking from not actually having done this, just stuff I see as I do V8 swaps into S10s and S15s.
