    Hey guys, i've searched but with no luck to what i was after. I want to know how the 3/4 diesels run a th400? Because the 400 is vac. operated, i wanted to know what i would have to do for the swap? also, would it bolt up to a 208 TC? My 700r4 took a big poopy on me, i'm evolving my truck to be mainly just a trail runner and i'm just looking for a tranny with some more balls. Thanks for any input.

    Its an easy swap, you will need the transfer case, adaptor, and transmission. the th400 has a 32 spline output. And the 700 is 27 splines. You should lalready have a vacum pump on your truck so you just need the corrosponding TPs for the 400, it runs off vacum. i just pulled this complete set up out of my blazer if you can't find one local.
