Transmission warms up fast

[60POWERSTROKE73]

Ok guys I have a a question, my transmission after about 10-15 minutes of driving through town will heat up to about 180F, according to my glowshift gauge, when I first put the gauges in the truck the temperature wouldn't even touch 150F. It was about 95 or so out that day. I think this isn't normal or is it? Is there something I can do to make it run cooler? Mods are SCT with IDP's x-street loaded in and the straight pipe and nothing else. Also when it hits about 183ishF on the gauge it slowly cools down to about 170F-175F range and will stay there until I shut off the engine.

That's the thermostat operating. It's working as designed.
