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!


I have a 2WD 1982 K5 blazer which had a 1991 700R4 and just reaplced it with a TH400. I will be willing to swap you transmission crossmembers because you'res will not work. I also have the kick down cable and any wiring if needed.
