I need some advise here.
This is an M12 trans that I am rebuilding. But my manual shows a different assembly for my 3-4 synchro and blockers.
I looked on the Nalley site at the sub-assembly exploded view as well.
They both show a single carbon-fiber cone inside of a single blocker ring for both 3rd and 4th.
BUT my setup has a carbon cone inside of a carbon cone inside of the 4th gear.
The 3rd and 4th blocker ring are identical as well. but they are listed as different parts and prices on the sites who sell them.
Help me I'm drowning...
I have. I ordered a 4th blocker ring. I'll find out in a few days if that is the problem. I only have the one trans apart but I *think* that somehow I have two 3rd blockers and no 4th blocker. Very strange.

blocker.
You are looking at the manual for double/single come T56 (Viper/F body). The Corvettes have triple/double cones. Second from the left is 3rd gear blocking ring and the third from left is the 4th (same as 5/6th) ring. Hope that helps.
I have the transmission together. I bought the thing a few years ago and the guy claimed that it was a fully functional transmission that had never been opened.
When I received it the black silicone oozing out from the housing joints told me a different story...
Once I received some guidance from a local transmission shop it appears that the PO had been into it and swapped the 4th blocker for the parts in the picture.
No wonder the input shaft wouldn't turn.
These things are pretty easy to rebuild when one has the correct parts.
My thanks for the advice that I received!
