AX15 manual transmission fluid?

What type of fluid do you guys put in to your manual AX15s? And how many quarts?

Thanks!

I looked on Shopkey and it said GL-5 (synchromesh) or 75w90. It doesn't say how much though. It says unavailable. I looked up the older ones which should be the same and it says 3.5 pints

If I'm not mistaken they now recommend 10w-30 synthetic motor oil. I researched this before I changed mine and all the vets say this. So I did and have never had a problem.

That sounds about right! I have a 3 cylinder Metro for gas mileage and it calls for GL-5 which is Pennzoil Synchromesh but other trans shops also recommend synthetic 10w30 instead and has about the same feel to it.

You'll be fine. That is originally what's called for. Just curious, what was in your trans when you drained it?

Okay sounds good thanks. In my tranny, the fluid first came out grey. Then turned brown and had white stuff in it. Then the white stuff stopped and the rest of it was just brown with what looked like dirt and crap in it. New tranny fluid made a world of difference.

Not sure what year TJ you're referring to, however, i did a lot of research on my 97 TJs AX15, and determined several things. First, the OEM service manual was a misprint mentioning GL5 fluid. It was corrected, but the misinformation persists. Apparently, ONLY a GL3 equivalent fluid should be used. Mobil 1 75W-90 is GL5.
From what i've read, GL5 is corrosive to the gears in the AX15, hence a big no-no. If you've filled it with GL5, id get it out pronto.
I just filled mine, used Penzoil Syncromesh and some Lucas Oil Stabilizer. Noticeable difference, after a few days of driving.
Do a Google search under AX15 and Fluid and you'll find the discussions.

Redline MT-90...or MTL. One is thinner and one is thicker. Fill up till it starts to ooze out of the fill hole. Pretty simple.

DO not use GL-5 stuff! That is a misprint in the manual!

Use GL-3 or 4, or 10w-30 synthetic, or MT-90

Not sure if oil has ever been changed in my ax 15 trans. Should I use the 75w90 or go with 10w30? Don't want to change out oils and screw something up. Had a 5 ton truck in Afghanistan that I changed tranny oil in, it never ran after changing the oil until we swapped out trans.

Its GL5 Gear oil for AX15.




Personally I only use Royal Purple Fluids, they are 100% synthetic and have been proven to greatly reduce friction and heat, as well as improve gas mileage.

Use full synthetic 75W90. I finally changed to that and my Ax15 never shifted better. It has never been that smooth.
