Tranny fluid temp & cooler
At what temp does the fluid start to hurt the trans? Above 150, 200? I want to put in a cooler to prolong the A4, but where on earth can you mount it?
Thanks all!

above 265 is when the alarm goes off. most trans temps for moderat use run low 200s temps
The Autos have a trans cooler already. Some ppl add an extra small cooler in front of the AC condenser

Here in California, mine runs at 145* all day long in the summer. I have a B&M cooler that straps to the front of the radiator/ac condenser. I also bypassed the stock cooler in the radiator all together so the B&M runs stand-alone. This is a very easy do-it-yourself mod! I probably would not bypass the internal cooler if I lived in colder regions of the country because the stock cooler brings the temp up much faster since it operates with the radiator and its coolant temperatures.

Here is a chart that shows what happens when you reach certain temps, and also shows what the temps should be.

I've seen this type of graph before, but it does not state what kind of ATF fluid its based on. I can't see one graph covering modern and legacy transmissions with a high degree of accuracy, but it could be a good rule of thumb.
I would not be real concerned unless you were setting off the high temp warning/alarm. Or getting real close to those temps for long periods of time.
I would be more inclined to flush the fluid and filter, but the regular interval for that is 100k miles, so for highway driving not a lot of concern with the A4 IMO. If your taking your vette to the track you could hit those temps regularly, then its a concern.
