Transmission Getting hot!

My dad has a 2002 f250. Driving normal, about 75 degrees F air temp out, the trans will be a little less than 150 degrees. (He has autometer aftermarket gauges). Usually it can be 90 degrees out pulling our 20 foot boat and be around 165 degrees. Well yesterday i noticed it hit that mark, and decided to keep on goin. By the time i made it to the shop i was at 225 degrees.. He put it on the scanner and told me the acutal temp, and there are no codes. He and i thought for sure that i was slipping a converter or something internal with the clutch packs..

He asked me if the truck felt doggyish and it did dog down for some reason earlier in the day.. Well we took a look at the air cleaner and it was packed full off the white fuzzy crap thats falling around my house this time of year.

So he was thinking the motor was working harder and in turn making the trans work harder.. I cleaned the air cleaner and i dont get above 180 degrees but it comes really close still. Shift is a little abnormal but he said at 200 degrees your fluid starts to loose its properties... So im wondering if i can get away with flushing the trans and it will be ok..

The mechanic said he will drop the pan to make sure i have nothing major is laying at the bottom.. But what do you all think?

With all the white fuzzy stuff in the air box maybe it is stuck in your cooler?
