I typically try to flush the transmission every 15k in both vehicles--have done it since they were new. The GMC probally wont hit 15k until christmas (15k on the odo..) and the Grand Am will get it in a few weeks.
I change the filters around every 30,000 AFTER I have them flushed out.
With the GMC I will probally go with an AcDelco filter and refill with standard ATF---then have it flushed with Mobil 1 ATF (Unless someone can convince me otherwise)
The Pontiac will get the opposite---flushed then the filter change.
I am a firm believer in flushes--if you do them regularly there should not be a problem. BUT if you have never done it, and the ATF is like Log Cabin maple syrup..better leave it alone.
