The fully warmed temp will be a function of ambient plus a whole bunch more. The heat being dissipated by the cooler and tubing; engine temps which will vary with a/c on and off, etc. It is not possible to quote a maximum so a typical is what you get.

This is why I like the idea of a static reading for ATF level but it seems that automotive engineering refuses to go along with the simple idea.

97SL320 makes some very good points but I feel there is more to the story.
