trouble getting into gear from a stop

i just bought a 93 yj with 53000 original miles. it shifts fine when moving, but if im at a light and go to put it into first (or any gear for that matter) its is very hard to get into gear. if i have the clutch in when i come to a stop, and then put it in first, it goes right in. what could it be. i dont think its the syncros because its hard to get into any gear from a stop. heres is my list of possible causes, tell me what you think.

clutch needs adjustment, or is low on hydraulic fluid (does my jeep have a cable or hydro clutch?)

tranny is low on fluid or needs fluid replaced

shift linkage is out of adjustment (how do i adjust it or can i adjust it?)

just looking for some help and ideas before i start working on it

thanks

I've had this issue on and off for the past 4 yrs.
Whenever I change my tranny fluid it goes away after driving a few miles.
In my case I 'm assuming the fluid change is a temp fix.
I'm hoping to stretch this temp fix out as long as possible. Maybe another 4 yrs
I use redline in the tranny.

synchros. try to give the engine more rpms before you shift and see if that helps. also change the fluid more often like ufatbastehd said

I think its the piolt bearing - it realy doesnt come into play at any other time when shifting other than a dead stop.

Check the fluid level in you clutch master cyl.
If it's very low or empty then you have a leak.
Top it off with brake fluid and bleed the system.
Now to find the leak...

Leaks usually occur in two places
1) Clutch Slave cyl. Look for fluid dripping from the bottom of the bel housing.

2) Clutch Master Cyl. Lokk for fluid leaking on the INSIDE of the jeep where the puch rod goes from the clutch pedal into the firewall.

That is exactly what I had, no leaks, master c fluids all OK
Tranny fluid change like I said helped.

Lets hope that's all you will need

ok today i replaced the tranny fluid with some fresh 75w90 oil. i buttoned everything back up and took it around the block, but the problem still persists. i only drive maybe a mile at most, so it may go away once i put a few miles on it, but i doubt it. i also checked the fluid in the clutch master cylinder, and it was exactly at the level where it should be. not sure how old it is though. so ive narrowed it down to this:

shift linkage needs adjusted
bad pilot bearing

how do i adjust the shift linkage, or can it even be adjusted

and to replace the pilot bearing you have to drop the tranny right? that means i have to drain all the fluid i just put in and fill it back up again (a MAJJJJOR pain in the ***)

any other ideas? im 99.9% sure its not syncros bc its hard to put it in any gear at a stop.

also, if i am rolling ever so slightly, it will go into any gear fine. another syptom of bad syncros, i know, but i really dont think it is. please help, **** lke this drives me crazy

I have a 93 YJ with a 2.5L with an AX5 with 50,000 miles on the transmission and am have just started having the EXACT same problem. I have Amsoil trans fluid.

I am curios as to what it could be too.

Like I posted earlier when I changed my fluid the problem went away after a few miles were driven(bout a week or two) I only drive it 3-5 mi a day,

When you changed the fluid did you notice any metal shavings on the magnet?

Is the oil you put in a good synthetic tranny fluid?
I use Redline and my tranny shifting issues seem to always go away after an oil change. My rig is shifting smooth as butter now.

Good luck

there were just a few small pieces of metal on the magnet, what i would call normal. barely even worth mentioning.

the tranny fluid that i used was a mid level fluid, not mobil 1 or redline or anything like that. i am a firm believer that they are all about the same, most are even made by the same company. many tests and write ups have proven this. so anyways, no i didnt drop money on top shelf tranny fluid. ill let you know how it goes after a few more miles. thanks for the help

I have the same on my 93. I used Redline MT-90 and it got WAY better. Once in awhile it will still happen, but I can usually put it into second for a quick second then into first and it will then go. But mostly it's not a problem after the Redline went in.

What AMSOIL fluid are you using? I know a few folks run MTF (Synchromesh), AGL (80w-90), and the old series2000 in their AX-5 and 15's however the only AMSOIL fluid appropriate to these transmissions is the MTG Manual Transmission and Transaxle Gear Lube.
