What happens if you go from 5th to 4th? Your blocker ring might be toast on 4th.

Is this after going through the other gears? How much power are you making? The master would cause the problems in all gears as it's not selective, have you confirmed the clutch is fully disengaging? If you think it's the trans, you can drain the fluid and refill if it hasn't been done in a while to see if that helps.

Have you done any trans work? If so, have you changed the 3/4 shift fork? Weak link in T-56.

The trans needs to be torn down to replace the fork. The upgraded fork is steel, where the stock one is aluminum. Also should check the blocker rings and the keys while youre in there.

Rob has it right, this has to be happening as a result of an internal issue. That would affect this specific shift, allowing all others to work properly.

$600 is resonable for a out of the car trans rebuild for labor. I did it all myself because there was no one in the area I could afford or trust (Hawaii). About $100 in special tools and you're gtg. Was a fun project.
