Being that we live and do most of our RVing in the four corner states we have hit those temps as well on occasion. Mentioned it to our mechanic at least a couple of times in the past and he didn't even blink, just said it was typical under extreme duty and synthetic transmission fluid could handle it. As a precaution I have a total tranny fluid flush every 25K miles although the last time we did it our mechanic said our tranny fluid was pink and still had plenty of life.
