John, I am no expert -- but I have a friend who is a Toyota repair guy (not a dealership -- he has his own shop with several employees) and he said that as long as the temp is below 230, I will be ok. It has never gotten to 220, and it rarely gets over 190. He said that the problem is not the fluid, which can withstand a lot of heat -- it is the components of the transmission that can be damaged by heat in the 250 range. And he said that the Scangauge monitors the temp before the the fluid goes into the cooler, which is why the temp varies so quickly. The Tacoma with the towing package has a trans cooler.
With that data it would seem WS can handle more heat than the trans, which is normally not true with ATF.
I saw up to 250° a couple times doing some slow speed driving, it climbs very quick when the tq converter won't lock.
Doing some 4wheeling I saw it above 200° frequently, but not much above that.
I had the towing package with aux trans cooler.
Yes the SGII will monitor the temp in the pan. IIRC Toyota doesn't have their AT TRANS TEMP light go off until something like 375°, so it is more of a "new trans" light than anything. At least that's what it was on the older trans'.
