Sounds excessive. I wonder if a snap ring or thrust washer is missing.

I pulled the shifter cover on my spare T-177 and shook things around. Feels like only .005 or so on the 2nd gear. Less than .010 for sure.

hmmm. Yeah that should be less than what I had. I guess the T177 is the same except for the gear tooth count. I just don't want to shim something I'm not supposed to, assuming that is what is causing the difficulty to get into 2nd gear.

Was it jumping out of gear? Excessive endplay can cause that often times going up or down hills.

I noticed it jumped out of gear once going over a speed bump recently.

I took the cover off. Everything looks normal. My synchronizer plates do not pop up cockeyed when I slide the collars. Trying to send you the video bob. As of right now it says file exceeds maximum size.

I can't seem to upload the video I made. But I wanted to say that my first -second gear synchronizer assembly was new a year ago. My friend was suggesting it just might be tight........ When I was just out there looking at it I also noticed that 1st gear had the same amount of back forth movement/play. So I don't know . Does that tell you anything ?

Do they come out of the assembly, or are they still flush with it? Mine would have one end pop out and that would jam it in third gear. I wasn't able to shift out of gear unless I physically got in there and pushed them back into place. They should have some play in them and slide back and forth a little bit, but not pop up out of the assembly. If their popping up and out, then somethings worn and didn't get replaced in the rebuild that you say it had.

The plates stay flat when I slide the collar

So ofcourse the shift tower is removed from the tranny right now. And I was just messing with the shift lever(stick) and when I tried to put it back on the tranny it the shift forks were not lining up and the stick was lost as hell, like it was stuck in a gear and the stick could move all around like it was in nuetral. You think this is related to it being hard going into 2nd gear ? I suspect if the stick isn't in the shift fork lug right it might make it hard to shift because if you're sliding the synchronizer assemblies by hand you have to be pushing on them kinda just right to get it to slide on...........
