High auto transmission temps?
I have started to monitor the transmission temp of my A6. Today the outside air temp was 85 degrees and I was stuck in stop and go traffic. The transmission temp creeped up to 207 degrees. When traffic started to move again, the trans temp dropped down into the 180’s. The water temp never got above 210 degrees.
The high temps of summer aren't here yet, so what is considered a high auto transmission temp?

At 240-260 degrees, the trans may make a DIC readout that says to slow car or let trans cool down (paraphrasing the manual). Since the stock trans cooler allows the engine coolant to run through, you may see slightly higher than coolant level temps in the trans temp readout. My A6 had catastropic failure at 260 degrees, according to the tech that disassembled it to verify it was indeed a factory parts failure and not abuse.(it has a sort of data recorder in it's computer).Using the paddles will also increase the temp to a higher level faster than letting it shift it's self.

It took me lots of time/money/trials to figure out how to make mine run that cool with my set-up.

so what is everyones cruising temp and idle temp in traffic.
Today was 97ish degrees out
cruising temp was around 197
idle temp crept up to 208
is this normal. Just wanna make sure because my headers are maybe 3 or 4 inches away from where the tranny fluid circulates.

I heard somewhere if your stuck idleing for a long peroiod of time( stuck in stop and go traffic, long red lights etc.) putting trans in nuetral will take strain off and allow it to cool more easily. I do it when I can.
