Nope....at least not until something breaks. Mine was low and I did not realize until 5th gear started making a noise like a bag of marbles bouncing around under the hood....and even then it still shifted and pulled fine in 5th.....just noisy as hell. Drove it like that for 3 months.....didn't use 5th.94redwrangler said:well i have a question. would it make it hard to shift or make your gears stick if the fluid was low?
I started to change the fluild in my 1997 wrangler maual trans. and found the fill plug would not come loose! After about 1.5 hrs., I gave up! This is after I finally stripped the torx type plug. I tried everything including a hammer and chisel! Need help! Are these plugs always this difficult. Any suggestion now would be greatly appreciate. Yes, I usally do all my maintenance! Help!According to the factory service manual... ...it's 75w90 in the transmission (3.27qts. in the AX-15) every 18k mi, and ATF in the transfer case (3.25pts in the NP-231) every 30k mi.
So the O&M is incorrect in stating, "Mopar Gear Lubricant or equivalent of SAE 75W-90 (API-GL5) quality." ?????If you have a ax-15 you need to use a gl-3 or 4 oil not a 5. 5 is what all the auto parts stores carry. Get a oil like redline mt-90. If you use a 5 it will eat away at the syncros and will trash the tranny.
