Little Rattle/grind when shifting

Need some help, I know this is a common issue and there are plenty of threads about it but each one is different it seems so I just wanted to post my problem and see if you guys have some suggestions. I just bought the Jeep about a month ago its a 94 2.5L 5spd I'm assuming it has the ax5 and im not sure if its ever had a rebuild or not with 125K on it. I'm starting to get a little rattle/grinding when i first change into a gear and im at low RPM's , it goes away after i get past 2,000 or so but its making me a little nervous, cant really afford a new trans right now. Is this something that could possibly have to do with just changing the gear oil in the trans and differentials or is she gonna go out on me? what do yall think?

If its a 94 and has the 2.5L, then it has an AX-15. Is it grinding as you shift or while driving?

Sounds like your synchros might be going. You can either tear apart the tranny to replace them or just learn to deal with it. As long as your RPMS between the shift match the RPMs after the shift you should be ok. Or learn to double-clutch.

Bro, i had the same issue, i unplugged the fill hole only to the manual transmission and then i pumped out 2quarts of old fluid. Replaced the 2qts with Pennsoil Synchromesh from Autozone.

things are better now.

Make sure that your drain your tranny and fill it back up, they will start grinding a little when the fluid gets low(particularly 2nd and 3rd for whatever reason).

Also check your rear driveline seal assuming you don't have a SYE. Those seals go bad a lot, and can throw tranny fluid all over your body without leaking much on the ground so you don't notice it much. It causes your fluid to get low, and you don't even realize it.
