[QUOTE="Gilaguy23, post: 429469, member: 19498"] (API, American petroleum institute) By no means insinuating you have or had recommended that one. I Just mentioned it as most auto parts stores Ive been in will tell people that MT-1 means it great for ALL manual trannies. They typically direct you to Mobil 1 synthetic GL5 or something with that spec. For that matter with the exception of our local Napa GL5 is all you can find in my neck of the woods. And like Macho said every AX15 or AX5 equipped jeep Ive owned did not shift well with dino 75/85 or anything of that brew. When its in the teens here its near impossible to shift into any gear. The Redline did help my 98's AX15 but Im just running straight 30 or 40 HD in my AX5 now and change it every year or so. Shifts buttery smooth. In you case, Id say things are getting worn out. The thick oil is great when things are cold but once heated up and thinned out you start to get hard shifting dues to syncro wear. Just my $.02 on that one. [/QUOTE]
