I converted my A4 to 3:42's and a 2800 stall. Even, in 90+ degrees and driving hard my trans temp stays ~ 175 - 180 degrees. HTH

Prior to doing the 2800 stall on my A4 175-190 was typical operating range.
After doing the stall, it would spike up to 220-230 very quickly if pulling lots of hills or when putting my foot into it...and take a long time to cool back down.
Added tranny cooler and now it's back to the pre-stall range!!!
To the OP...if you're seeing 275+ temps...you're doing harm...get a tranny cooler
Also, if you have a stall run in 3, not D around town...and your converter should lockup(assuming you have a lockup converter) at a slower speed thereby reducing heat.

I've been wondering the same. I have checked mine many times while driving around and it seems to stay close to water and oil temps. If I do a bit of shifting then it climbs a little higher. I have A4, standard everything.
I could not find anything in the owners manual about temps, but you can see what they are.
I think the highest I've been is about 210 when other temps can be 220 or so. When just cruising down the hwy, my trans temps seem to run lower than water, oil, maybe by 10-20 degrees.
On hot days and sitting in traffic my trans temps seem to get to the highest, but I don't think I busted 220. Water has been 220 plus on hot days.

Driving around yesterday in 75*F weather, I saw a high of 201*F. Its usually in the 180s or 190s when fully warmed up and driving around town. Haven't beat on it for a long enough time at once to see it go any higher.

I have heard that you never want to power flush an auto transmission. You could knock loose built up tarnish from the inside and it could clog up your valve body. I'm not a A4 expert, but I would like to know if it is true.
