You've got the wrong guy. I was just trying to help you earlier (remember the "you didn't actually strip your pan threads" among other helpful posts?). I don't care what you put in *your* trans or whether you agree or disagree with anything I have to say.

And you would know my experience level how? If you can't tell by my posts that I know a bit about cars and Toyotas then you might just have a reading comprehension problem. If that last statement was just supposed to 'hurt', then I'll play along. Boo hoo.
By the way, Honda ATF Z1 isn't well thought of either.
BTW, whooptydoodles.

Relevance?
Tegger, like Toyota MDT, I think you could also learn a lot from the folks at the

Been there. Chat with experts I trust on the subject and read SAE published papers. Do this for a living and am among the minority in this business that care about which oils to use in my customers' cars and my own cars. Tegger is no dope either. Lay off him or he won't be there to help you when you, for example, can't find your coolant drain plug.

So I made light of your multiple statements about the unbelievable nature of all of this. It was intended as a good natured rib and the rest of the post was intended to clear up some potential confusion. Apparently neither attempt hit the mark.
If you have a transaxle issue within the 5/60 powertrain warranty, are you going to volunteer that you used non-approved oil in your transaxle? If you were in Toyota/Asin's position, and had to warranty your products - given that approved fluid must be used - would you be so quick to hand out free transaxles, labor comps, and paperwork on failures that had non-approved fluid changes?
That was highly hypothetical since you aren't going to have any problems with that trans for a long time and the Mobil probably isn't going to cause any damage, but it is something to think about and answer honestly. Manufacturers don't just spec fluid willy nilly. Manufacturer approvals (when an aftermarket source for an equivelant oil exists) aren't quick cheap affairs either.
