I have a 1985 chevy s10 blazer 4x4 with a 2.8 v6 it was fuel injected but I put a holly 4 barrel carb on it but sadly my tranny is starting to slip. I was hoping that maybe someone knew or could find online the transmission size I've looked around for it but don't really know what to search for. THANKS!!

Call any local wrecking yard and they will tell you what will and will not fit. In that year it is probably the TH200 which was a piece of junk from the get go.
