Sticky shifting but not always???

This is puzzling because it's not happening all of the time. Every now and then it's difficult to get into first gear and once in a while it will ever so slightly grind or catch going into second gear. All of the sudden it shifts like butter for a couple days in all gears. This has been happenning off and on and I would think if the syncros were going it would happen all the time, no? I had a slight clutch m/c leak and repaired it with a new one and it is holding fluid fine now. The trans fluid is fresh and recent. It's a little sticky to get into reverse at times and I'm wondering if it's in the shift linkage or the pivot piece at the bottom of the shifter. I hear a funny noise from there when I pull it into reverse. I don't remember what it's called but I think it's a ball and socket like thing. Would I be wasting my time to inspect that?
Thanks

I had the dealer change it six months ago when it was in for a bigger repair. Long story but I've used this guy for years for the tough stuff I can't do and had him change it when it was in the shop so I'm not sure what was used. I've read about using 10/30 motor oil and that was going to be my next question, should I try that and see if helps any.

I had the same problem sometimes, mainly when going into reverse. mine ended up being the shift boot being stiff and not flexing enough thus not being able to fully engage reverse, it was even worse when it was cold outside. i took it off and it shifted SO much better and without any problems. It feels like it is fully engaging into every gear. if you dont mind the look of a bootless shifter then give it a try.

It's funny but the noise I mentioned when pulling it back into reverse sort of sounds like it could be binding the shift boot. I'll remove it to see how it shifts without it. Can't hurt to try that.

Yeah let me know how it works, i found that out on accident. I never knew why it was hard to shift into reverse at times until i took it off to drop the trans and change the clutch and when i got everything back under the jeep i just drove around without the boot and realized how much better it shifted. good luck!

I would suspect a Slave Cylinder, myself....having experienced similar symptoms and that having been the solution.....

I replaced the clutch and the whole slave cylinder assembly on mine, and when i put the boot back on it was still hard at times to put in reverse and sometimes even popped out of reverse

Check your motor mounts and trans mount, make sure nothing has or is moving. If a motor mount is bad (or both) the trans can slide back. The trans can slide to one side if all the trans mount bolts are not tight..

Okay, I will check the trans mount bolts and change my trans fluid to 10/30 motor oil this weekend.
How do you check for worn or broken motor mounts?

The shift boot seems to keeping mine from shifting into second gear (and somewhat 4th), especially when it is cold. It will even pop out of second and reverse if the throttle is cycled. What would make the shift boot be that tight? I can't imagine it was like that when it was new.

I wrapped tape around my shifter a bunch times then I pulled the boot over it and it holds it up enough so it doesn't get tight or stick

Problem is the boot slides down and compresses on itself doing it harder to shift , esp in reverse

I changed out my trans fluid to synthetic 10/30 oil about two weeks ago and it seems to be better as far as the initial problem I was having. I'm not having any trouble getting into first gear now and my slight bite or grind going into second has improved quite a bit but is not totally gone. FYI for anyone having a similar problem.
