I'm familiar with the TIS as well as had this done several times by a reputable shop that walked me through it while we were under the car.

Everything I said is basically the same procedure as the TIS you linked.

- Bring trans to temp, check for fluid seeping out of fill hole

I'm not a big fan of passive aggressive so if you disagree with my opinion of what "up to temperature" is just say so...mon ami
The trans fluid cooling is usually tied in with the radiator. If the coolant from the engine at operating temp is 195F. than the atf fluid at the radiator is close to the temp of the coolant mon ami.

The transmission fill procedure is not complicated at all.

You need to have the transmission at normal operating temperature and when you unscrew the fill plug there should be a slight trickle of fluid coming out.

If you are worried about driving the vehicle then let the engine run until it comes up to temp (needle in the middle) and shift into each gear for a few seconds. R N D etc. Then check the fluid level.

Basically the trans fluid will expand when heated (like most fluid) so if you fill the transmission to the proper level while it's cold once you're driving around the fluid level will be too high.

The transmission shop that I deal with specializes in European cars and while I had my car there for a flush I was asking the guys all about the pain in the ass fill procedure. They said it's not that sensitive and proceeded to walk me through it on my car.

If you read how to do the fill procedure from the manual it sounds a LOT more complicated than what it really is.
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.
