Air? Shim? Syncros?
Chance of air in the system still? Are my syncros headed out the door?
I have seen local transmission guys talk about simple T56 repairs for "intermittent grinding going into third" on repair ads. Possibly that 3-4 fork is starting to go. When you do even a stage 1 upgrade to a T56, they upgrade the forks.
I guess it's easier to try a motor mount before going into the trans, but that sounds like throwing parts at it
