Outstanding post for those of us that have never been brave enough to get inside one of these tranny's. Question: What year 700R4 is your core and is there a better/worse core to get.

Reason I ask is that my original 700 in the 71 died and when I had it rebuilt I went with a 1992 and up core based on the tranny builders recommendations. Has been a good choice, this rebuild has lasted 10 years, just doesn't have many miles on it. Matter of fact, the road trip pulling the Blazer home to MO was its biggest test so far. It did great by the way. My engine wasn't very happy with the work out I gave it though.
