I don't think you could use it and not sure why you would want to bother. If you get a 5.3 from a RWD vehicle then any V8 or 4.3 V6 700R4 would fit (minus a bolt hole) and if your using the FWD 5.3 you'd want one from a 2.8 V6 S10 and if your keeping the IFS, you could get an adapter made to fit the Isuzu Tcase or run a Dana 300 since it is a small tcase. A guy on planet swapped in a 700R4 and Dana 300 behind the 3.2 Isuzu V6, which he used the 2.8 version 700. Now if you used a 700R4 you will have to fab a bracket on your throttle linkage to work the TV cable, unless you swap in a manual valve body, it's essential to proper function and the life of the trans (not too hard to make it work).
