should I flush it?

I have a 2002 f250 with the 7.3 and auto transmission. The truck overheated a few times before I could figure out the problem. I know when the engine overheats you should change the trans fluid. I've been told to get it flushed then I've also been told to just drop the pan since the truck has 202,XXX miles. I bought the truck when it had 170,000 miles on it and I'm not sure when/if the previous owners changed the fluid. The fluid definitely doesn't smell fresh now however. Any of you guys have an opinion on this?

Are flushes really that bad for a high mileage transmission? I thought the purpose of a flush is to help out higher mileage ones. Thanks for the reply by the way.

I'm confused as to why you would change the Trans oil if the motor overheats?

Your fine to change all the fluid, its easy and does not hurt anything.

Because of the trans lines going into the radiator. There is a trans cooler in the bottom of the rad right? I'm still new to this truck and honestly I don't know much about it.

If the motor overheats... fix the motor.

Don't change the trans fluid because the motor overheated...

I would figure out why the motor overheated? That NEVER happens on a 7.3 unless there are significant issues.

The overheating problem is fixed now. I thought the fan clutch was bad since I never heard the fan come on when it got hot, so I changed it. Still overheated. So then I went to the next easiest solution, the thermostat. It hasn't overheated since. The only reason I want to change the trans fluid is because I was told if the engine overheats then the trans fluid overheats too since it flows through the radiator. Is that not true?

If you have a combined cooler, your trans could've gotten hot, but who knows how hot.
Doesn't hurt to get in new fluid at all.

So yesterday I dropped the pan, changed the fluid, and filter. It seemed to shift better and seemed to be working fine. Then today (99 degrees in the shade here in Texas) the engine started overheating again after more then a week of running fine. So it seems like I have more work to do. Thanks for everyone's input on my original question, it's hard to find anyone knowledgeable on these trucks at the local part stores.
