['63GENIII]

I think by the time that you spend the money to get a 700 to survive behind a big block in a 1 ton, you could have easily had a used (or possibly rebuilt) 4l80e with the stand alone controller. Now if you're using the truck like a 1/2 ton, that may be a diffferent story. I use my 1/2 ton like a 1 ton and I'm looking 4l80 or nv4500 (manual).
