I change mine once a year. I put on about 10K miles, but requent the track as often as the weather is good and the car feels strong. I had just changed the fluid, after probably 50-75 passes, this summer, and about 8K miles, and there was a fair amount of metal on the magnet and the fluid was a little dark.
The more the better

I changed all my fluids when I bought mine this spring. I plann to change all my fluids each year. It's cheap insurance and I enjoy maintaining my car.
I won't spend the dough to get the tranny completely purged. I'll just do the four quart change. For my auto I suck the fluid out and THEN drop the pan. Much cleaner that way. I'll change the filter as well. Perhaps someday I'll get an aftermarket diff cover and trans pan that have drain plugs...I'll be sittin' in tall cotton then...

i agree with Mr. Incredible, all the fluid changes are fairly inexpensive and are just really good cheap insurance for your car lasting a long time. Why not. Same with spark plug and fuel filter changesl. If you do it yourself, it doesnt cost much at all.

Transmission/Converter Fluid Flush (F-body)
ONLY DO THIS IF YOU KNOW WHAT YOU'RE DOING
Read and understand the whole procedure before attempting.
You will need at least 14 quarts of ATF for the 4L60E (i.e. 2 extra quarts).
0. Get a 5 gallon bucket and "calibrate" it by marking off and numbering quarts.
1. Replace filter, gasket, pan, fluid, but do not start engine yet; make sure to put in same amount of fluid that was taken out (4-5 quarts).
2. Undo hose clamp on return line, pull hose from hard line, and direct hose into calibrated bucket (use an extension hose/tube to reach bucket).
3. Add 2 quarts via fill tube (using funnel).
4. Start engine, and while observing bucket, allow 2 quarts to come out (into bucket), then immediately turn off engine.
5. Repeat steps 3 and 4 until either at least 8 quarts are in the bucket, or you see new fluid coming out.
WARNING: DO NOT LET THE TRANS RUN LOW/DRY (PAY ATTENTION TO WHICH STEP YOU'RE AT)
6. Reconnect hose and hose clamp to hard line.
7. Start engine, briefly select each gear, check fluid level warm, adjust if necessary (add/remove fluid via fill tube), check for leaks.
This flushes the converter because the converter fluid exits thru the TCC valve into the cooler circuit.
The cooler return line feeds the lube circuit which is critical only if the trans is in gear and under load.
DISCLAIMER:
Some people say that doing this is not good for the gearsets and bearings inside the transmission.
I have not had any problems from this, and various other people have not had any problems either.
BUT please do NOT do this if you're not comfortable with it or not familiar with transmissions in general.

Wow, I have no idea why someone would rather buy a new trans than replace fluid and filters every now and then. It's not that big a deal fella's and you're screwing yourself out of money in the long run.
Open your owners manual and follow the instructions. It's terribly simple. Most people daily driving their cars in the cities are in fact under the severe use schedule.
REMEBER: A trans fluid/filter change is MUCH MUCH MUCH cheaper than a trans rebuild. If you follow the maintenance schedule you will have very few problems under normal use.
