When I checked the transmission level after a 40 minute trip, mostly freeway, it appeared on the high end of the 90 C marks.

When I checked the level after a 5 minute drive, it appeared a little low of the lowest 30 C level. What gives?

Has the ATF temp exceeded the 90C in the first check and hasn't reached the 30C level in the second?

I'm using Mobil 1 synthetic ATF. Shifting seems fine.
