The normal operating temp of the trans is NOT 30C to 50C temp. It is a lot hotter. Like you stated ATF expands when it is heated and contracts when it is cooled. So if you do your check at "Normal Operating temp" the ATF would have expanded considerably and if you let it dribble out, by the time it contracts when it has cooled, the fluid level will be LOW mon ami.

Like I warn people watch out for the Cliff Clavens on ths forum.
