[QUOTE=pokey;1060901]Your '99 was the last year jeep used the AX15 and they discontinued the original Mopar fluid for that tranny. The dealer now recommends Mopar 10w30 motor oil for the AX15, which is fine. Or any 10w30 motor oil, preferably synthetic. The Redline is an excellent fluid for your tranny, it's what I use. You may have other issues. I think the Redline is the best stuff out there for the AX15.
edit: your profile says you have a '99 but your username says 05 LJ
Thanks, yeah my 05 LJ is my baby and my 99 TJ is my project trail rig.( i need to update my profile) I may have issues with the tranny among other things
but it seems solid, I take it to neutral now when shifting to 2nd instead of throwing it straight back and hearing it grind and I let it mesh in to gear.
