I replaced the 1-2 shift fork and now can't shift into 4th gear. While apart I replaced the shift fork rod detent springs and ball bearings and the shift lever and guide pins so there's no slop in the shifter. So the fork shafts are moving freely and it shifts smoothly in all other gears. It feels like it's partially into 4th but not fully engaged. I've tried turning the input shaft as I try to shift with no luck. I'm stumped guys.

Posting the same question in multiple forums is against Stovebolt rules.

Are you sure you have the shifting forks lined up and in the sliding gear grooves?

The "post in one forum rule" is not shown in the "rules".

I'll keep looking - maybe it is in the "manual" if I can find that (or, in "forum help")?

The "Forum Help" link at the bottom right on this page does not work.

I think there is a "user manual" somewhere - I'll keep looking.

Does a new member get a link to that manual, or, a link to the "rules"?

Tim, you can find it in Cletis’ Sticky at the top of GTT.

The whole "can't multiple post" thing is more of a guideline than a rule that we would put someone up against the wall and shoot them for. Just a gentle reminder for next time. Tim's reference to Cletis' post is spot on. Golly, I miss that friend ... frown

Note to the OP -- the main thing is to get you the info you need, not to enslave you to the rules. We're glad you asked and we hope you get what you need. If you posted in multiple forums .... whoopy doooo. Just don't make a habit of it smile We can work out the rest. The moderators are only doing what they've been asked to do, so please do not take anything personally.

Thanks for using our site! Glad to have you here!

Regards,
John

Chevys till I D sounds like your detent spring might be coil binding . Can you move the 3-4 collar by hand with the lid off ? And get it into 4 th.

Yes, but I have to line up the synchronizer by hand. The shifter top shifts fine with it removed so that's not the problem. I'm going to pull the main shaft back out and figure out what the problem is. Any ideas what might be wrong guys. This is my first transmission rebuild, I followed the instructions to the letter but obviously something isn't right.

Chevys tillI d If you can shift your collars by hand maybe your lid is putting the squeeze on your collars. New gasket??or old (thinner) gasket ??
