Thats the weird thing about it, it only grinds going from 3rd->2nd. 1st->2nd no matter the RPM is a clean shift. Right now I'm running Redline MTL in it which is I think is a 70w-80 lube. Poking around HT and here shows that GM Syncromesh Friction Modified seems to help revive or give the syncros enough grip to work again.
