Grinds going into 4th gear 1964

[Ted K.]

Had transmisssion rebuilt, new bearings and syncros, replaced clutch at same time. Everything works fine but the gears grind going into 4th, (normal shift not speed shift). If I shift very slowly it doesn't grind.
Rebuilder thinks it could be linkage adjustment. How do I check linkage. Also could rebuilder have put transmission together in such a way that it would only grind going into 4th.
Thanks, Ted

I'm no transmission expert, but I just finished up rebuilding a 67 vintage Muncie along with a friend. (who was the real expert. )

It could be a clutch adjustment, but I would think that if that were the case, you would have issues in all 4 gears.

Did they replace the sliders and hubs when they rebuilt the trans? In my situation, I had severe wear on the second gear side of the 1/2 slider.

Wear, etc. on the slider can/will cause problems. New synchro rings will not cure it.

Sounds like the synchronizer or a blocking ring. I had one do exactly the same thing, had a small crack, not even all the way though, in the blocking ring.
