Use a GL-3 grade 90 weight gear oil. You may use a GL-4 or a GL-5 but the GL3 is preferred to increase the life of the syncronizers.

 

well I was told that GL-5 is exactly what you don't want to use.....but I'm a little confused........anyway I think I'm gonna get some REDLINE MT-90 That was recommended to me by a number of people. Here's my second question........how many quarts do I need??? At 7 bucks a quart I don't want to buy too many.

THANKS,

I got out my manual to check on the caps, no info on the amount only the normal fill procedure, fill till it runs out of fill hole. The manual states to use GL-5. My instructer at the Chrysler training center is the one that told us to use the GL-3 grade fluid.

 

I know that the Manual is WRONG.....DO NOT USE GL-5 that's what I've been told over and over again. Thanks for checking for me, anyone else know how many quarts the AX-5 5spd tranny takes?

 

The 99 AX5 requires the GL3 and the capacity is 3.3 liters ..or 3.49 quarts. I can only assume that yours is the same (qualified response).

 

I just filled the AX-15 in my '92 with Penzoil Synchromesh, and so far it's working fine. It's actually quieter and smoother than it was when I got the jeep. Plus, the GL-5 in it had a nice bronce tint to it.

Now, my new problem is that the clutch isn't disengaging all the way, making it a

to get into first gear. I noticed that it was a clutch problem when I had the Jeep on flat ground with the e-brake off. Without touching anything, standing still. Holding ghe clutch to the floor and attempting to put it in first resulted in the jeep rolling forward slightly. Let off the shifter, movement stops. *Sigh*

Time to rip the clutch assembly apart, and might as well replace it while I'm there.

 

I know this sounds a little obvious but.......is your hydraulic clutch resevoir full....I had the same problem on my F150, I checked everyting, turns out it just needed more fluid.

I used aprox 3.5 quarts filling mine up,
buy a hand pump to pump the oil into the tranny, otherwise it will be very difficult to fill ( try stuffing one of those bottles up there between the tub and tranny.

I picked me up a hand pump.......now I just need to order the oil...........NOBODY around here carries it. The auto parts store even said that they sell GL-5 to the Jeep dealer down the road. UGH.....dealers around here kinda suck anyway. Oh well gonna order some REDLINE MT-90 that should do the trick........at least it had better at $7 a quart

 

If you go to the dealer ...it's $15 a quart is a MOPAR label (probably repackaged Mobiltrans) and it's synthetic.
