grinding on my 1992 jeep wrangler.

hey guys, i just bought a 1992 jeep wrangler, for the first week it was fine but then grinding on third gear started, today if i shift from 2nd to 3rd it will grind badly; if i down shift from 4th to 3rd it will grind aswell. also 2nd gear if i roll to a turn in neutral, then shift to 2nd to turn, then most of the time it wount go in.. no grinding , simply it wount go in.. but sometimes it does..
i would like some advice from those of you that have had jeeps and know perhaps what is wrong with the car.. i took it to a mechanic and they say its the synchros in 3rd, maybe 2nd aswell. is this correct?
im planning on having it fix next week, but first would like to know the exact problem.. any ideas? also im in tampa, if anyone knows a good shop that can fix it? ...
so far i double shift from 2nd to 3rd to avoid grinding, it works like a charm but 2nd does not..

thank you guys..
my name is Juan, thank you for your time.

Sounds like rebuild time. How many miles on it? What engine size? If its the 4cylinder tranny you might want to consider upgrading to the ax15 of the 6 cylinder.

I would start by checking the transmission fluid. I would drain it then refill with syncromesh fluid. It can be a bit hard to find so go to a good parts store, not walmart. Drain the tranny and refill. I was having syncro problems with my ax5 when going from 2nd to 3rd. Did this and its not noticable any more. I have a feeling yours is worse than mine though. Still its worth a shot. In the long run you will need to have a rebuild or replace your tranny. You can take it to as shop or there are rebuild kits you can do yourself. I havent rebuilt mine yet, but I have heard its not that hard if you have the time and a little talent. I am sure if you search there is a write up about it somewhere, I know I came across something at one point. Another option is to ditch the relatively weak ax5 for an ax15. I havent looked into this option as much yet, but if mine goes this is what I will be doing. I know at the very least you will need to change the drive shaft(s) and probably the tranny mount and bellhousing possibly. Also I am not sure if the 92 has the external or internal clutch cylinder. That might have to be addressed also. In the end its more work to swap, but a better tranny.

I dont think it would be anything inside the tranny rattling. While your under there, look at the body mounts, linkages, exhaust mounts, fuel lines, shackles, track bars, sway bar.....basically anything attached to the frame for things that could rattle.

i saw this thread title, and was suspecting you were cutting stuff up for some cool mods. you know, grinding off this bracket and that tab. cutting and grinding the frame here, you get the drift.

i was dissapointed. lol

good luck with the tranny problem
