Ok, here is the official unofficial report:
After 214.9 miles since changing from GL to Mobile-1 10w30 my AX15 shifts better, and I mean noticeably better.
The added bonus is a reduction in noise. As stated earlier, my center console and tunnel boot are not installed at this time. Well, after about 50 miles of the trip I started noticing different noises inside my XJ--small air leaks, empty soda can rolling around, and some junk rattling in the glove box! These are sounds I never heard, or was unable to differentiate them over the trans noise. Totally subjective and "in the ear of the beholder", but I swear it is quieter.
So there you are, the official unofficial and wholly subjective road test.
I would do it again in. Would you get the same/equal results with a 10w30 non-synthetic oil, I don't know.
In closing let me say that this is not a miracle fix--I still have dandruff and athletes foot, so it certainly doesn't fix everything!!
