Transmission temperature

The fluid temperature in the transmission is the important number and that is where it’s taken.

Well, yes and no. Just like in an engine, the lubricating fluid temperature fluctuates throughout the transmission depending on the loading and what the fluid is doing. Typically the temperature probe is in a fixed location which isn't necessarily the location where the fluid is the hottest. The sensor measures the "average temperature" in a "convenient" location. So, even if you have a HUGE transmission cooler, it's a mistake to think that it sufficiently effects the fluid temperature in the hottest portion of the transmission. That's why it's important NOT to overload the transmission if you want it to last. If the ATF is showing signs of burning before your change interval is reached, chances are you are pushing it.
