I am rebuilding my transmission. The only real problem is the first / reverse operating sleeve. I had one on the shelf and a new syncro ring. The transmission had a problem jumping out of first. While I was there, I made some measurements. The shifter forks fit in the operating sleeves in a groove. There are 2 measurements I made. One is the wear on the thickness of the fork and how much slop there is in the groove. I used feeler gages to measure this. The other wear in more of a diameter of the shifter fork. As it wears the diameteter gets larger and the fork can rock in the sleeve. Here is a picture how I measured this.

The side clearence: Would rock (diameter wear)
first / reverse .010" .028"
Second / Third .003" .060"
Fourth / Fifth .003" .060"
It appears to me that the First / Reverse is worn thin. I think it is in specs.
The other 2 seem to be worn in a diameter (fork would rock back and forth) maybe a bit too much. Can anyone tell me if these forks are O.K.?
