Interesting issue..
At first it wouldn't engage, then I got it to go in messing with it. Now every time I go into 5th from any gear it will go in smooth..EXCEPT from 6th..it blocks me out. From there it will go in when you lift the clutch up, and even then it engages smooth. Trust me I'm baffled..lol
I can see it possibly being something caught on the Synchro..I say that cause if you think about it when you come into 5th from anything before it the internals are spinning faster than that 5th and they mesh fine. From 6th to 5th it will have to make the 5th Gear spin up, and it's blocking it out instead.
The Synchro is the only thing that makes sense to me..maybe something in there got stuck on it and it's not catching that 5th Gear until some pressure gets put on it.
It's not grinding or has any resistance at all once it slides in..it's either a total block out or right in.
It just started all of the sudden so hopefully whatever it is will work itself out. If not I'll pull the Tailshaft Housing and see what it is..prob something simple.
I may just switch the 5th and 6th Synchro Ring..I'm not down-shifting into 6th from anything..lol
Let me know what you find on it Mike if you dont mind..
