Stand alone transmission computers are available now, pricey but available.

What tranny does it have?

1/2 ton or 3/4 ton donor truck?

If it we me, I'd keep the over-drive tranny and do whatever it takes to make it work.

the donor is a 1/2 ton 2 wheel with a 700 r

bdas70chevy,

If your trans is original, it should be a 4L60-E. It is basically a computer controlled version of the 700R4. You will need to remove the tail section and replace the output shaft with one from Advanced Adapters that will work with your 205 transfer case. Also, you will need a high pressure inline fuel pump and a return fuel line installed. Your stock computer will need to be reprogrammed to get rid of the code that you will not be using for emissions and anti theft modes.

I am thinking of the doing the a similar swap using a complete rolling chassis from a 1999 Tahoe. I have found a place called BTB Products the does a lot of these swaps and has most of the parts and services to help you out. Also , Howell Engine Development has a lot what you need, but I have yet to talk to them and see how complete their services are.
