ok,

My 89 Burb has a th400 in it right now, with the 350 engine. I just picked up a 700r4 from what I think was a 86 blazer. It came with the transfer case also. Anyway, this is a direct bolt in right? I know I need to move the crossmember back a set of holes, and I was told the 400 is just about the same length as th e700, so the driveshaft can be reused. My biggest question is the tc lockup. Do I need extra wiring for the tc? Thanks!
