The mechanic might be right. I have read old posts here where someone flushed the ATF on their very high mileage car and then the transmission conked out. The theory is that the crud is holding the bands since the lining material is gone, and once they flushed it the transmission didn't work anymore.
Anyway i think there's one of two approaches to take. Either leave well enough alone and DON'T change the fluid (since it still works, after all). Or, maybe just try a drain and refill, which takes 3 quarts, and leaves about half the dirty fluid in place. The benefit of doing this is you'd get enough fluid in there for the additives to help refresh the old fluid, and get some of the dirt out, while possibly not killing the transmission.
Personally, i think i might leave it alone.
