Oil Mess and Syncromesh, education on tj trannys
Some of you may already know this, but it caught me by supprise. Aparently in 1997 jeep FSM came out with a misprint recomending gl5 lube for the ax15 tranny. I being a good jeep owner change the lube 2 times a year need it or not. So you can imagine my supprise when my syncro's started grinding. After allot of worry and conciderable research I found that the gl 5 was a misprint the lube should be a gl 3 same as the YJ's. Aparently Gl5 contains sulfer which can harm yellow metals (Syncros) I found allot of information on the Four bangers united web site supporting this. Pursuant to the information there and almost a compleete unavailability of gl3 lubes at the parts houses I had 3 choices:
Factory recomended oil, 15.00 a quart at the stealership
Redline mt90 could not even get a price on it or a carrier in my area.
or GM Syncromesh retails for 10.99 a quart I paid 6.00
I ended up choosing the syncromesh, Now my grinding is gone, and the trany actualy makes less noise.
I was not thrilled and it took a leap fo faith in the guys at the 4 bangers site, because being a GM fluid there is not allot of product information on the specifics of the oil. But so far so good. As for jeep I called the parts office, and they of course said that they were not aware of any missprints, but cofirmed that it should be gl3 although after talking to the guy I was not impressed enough to put allot of stock in what he said. But he did look it up.
Oh the mess I almost forgot. I installed a warn engine skid before the spring bash, so I had not changed my fluid since...

I posted this because although I read everything I can about my tj I was not well informed on this topic and it will eventualy cause my tanny a quicker than planned death. I asked the wal mart guys when I was in last week, and they said they put gl5 in the trannys, so I suspect that they are using the same false info I was...
As for the info, dont take my word for it, Research it, and post it back here so we are are enlightend...
Has anyone heard of this?
