Here's my question for everyone.
I've been told on numerous occasions that for our particular model transmission (ax-5) that we are supposed to use only GL-4 80w-90 gear oil. Something with the sulfur in the GL-5 eats away at the brass syncros and causes harsh shifting. YET in all of our owners manuals it states to use GL-5? Can anyone help me with this? It's been bothering me for a few days and I would love some clarification. Thanks.
I thought it was GL-5 that ate the stuff. that was the case with my CJ5's transmission anyways. Had to use GL-4 for that reason. I am somewhat confused by your post. You seem to switch it around.

There was a recommendation change to use 10-w40 for the ax-15 and I believe the 5 as well.
That was the recommendation I received back when I had an AX-5. I switched to 10-w40. Not sure if that was the reason, the simple fact that the PO never performed regularly scheduled maintenance, the way my son drove it, or that it had 175k miles on it, but a year later we lost 2nd and reverse at the same time. Ended up replacing it with a $200 bone yard AX-5 then sold it three weeks later. What a turd that AX-5 was. Between 5th gear going away and the overall light duty nature of the trans, I'm SO happy I dropped it like a bad habit.

I have always read/been told to use GL-4 in the manual transmission. I have also heard about the switch to 10w40 but currently am using redline synthetic 75W90 GL-4 oil in my wrangler.
I did a bit of research and the general consensus was to use GL-4 since it is not as hard on the synchros. Im quite surprised your manual said GL-5... mine said GL-3. GL-4 i believe is considered to be a substitute for GL-3.
EDIT- I was thinking of my Haynes manual GL-3 spec. You are absolutely right, Chrystler listed GL-5 in the manual. Maybe this was for jeeps with only auto trans?
Been running 10w-30 synthetic (whatever is on sale!) in my AX-5 since I got it 4 years ago. Had almost no sychros left when I got it, and it is still going, even after much abuse. I have an AX-15 sitting in my garage but every time I run into the elusive Dakota bell housing I have no extra cash.

I appreciate all the help guys, I work in a dealership so I have access to lifts, my tools, all the goodies lol so draining and changing out wont be a problem. Anyone have any recommendations on conditioning the tranny before new fluids go in it? Just want to make sure EVERYTHING is top notch on the inside so I don't have any problems out if it.
