Just wondering if there are any differencs that I need to know about. I have a 92 RS and the tranny is getting ready to go, I also have a 86 iroc that was totaled and I had just had that tranny replaced with a new one. Will the 86 tranny hook up in the 92.. I know that there is a plug on th side of the 86 tranny but I haven't been underneth my 92 to see if it is the same.. Any help would be greatly appriciated.

All I know, The only visible diiference would be the 89 and older cars run speedo cables and the 90+ run electric ones.

The 1992 has all the upgrades, that the 1986 did not have, bigger input sprag, wider low/reverse sprag, smoother neutral to drive engagement, slightly larger boost valves, etc.

What do you mean by the 86 tranny having recently been replaced by a new one? It wasn't just rebuilt was it? Newer ones (even rebuilt newer ones) usually have the upgrades, especially if it is from a reputable tranny place. You would have to check the spline counts, and swap the electric speedo stuff to the new tranny, though.

I don't think the 86 has the 4th gear switch, that lets the ECM know it's in high gear. Confirmation?
