The 93 had a 4l60 tranny or the 6 speed without the electronic controls and yes its pretty much exactly like a 700r4 and its a easier swap to use that with a 93 computer but the 93 used speed density which doesn't react as well to mod's unless your very accurate with the programming which does have a removable prom chip, so you can't program from inside the car like 94 - 97. Also the 93 has smaller injectors (22lb vs 24.9lb on later), the intake manifold , fuel rails and oil pressure sending unit is also different and in a different location but the block itself is exactly the same but the heads are slightly different with some extra material around the under part.
