How many miles did you have on it?
I replaced my 1998 stock MN6 fluid with Mobil 1 at about 51,000 miles. This improved cold shifting. Ran that for about 51,000 miles, then shifting into sixth started to grind. I then changed to Amsoil ATD, it solved the sixth gear problem.
I hear that these transmissions are sensitive to dirty fluid, I don't understand why GM says no change is necessary?

Looks like, and probably smells like you were a little past due for a fluid change. Trans fluid should be pinkish. I did mine a 50K miles. The factory stuff still looked pretty good; and I replaced it with the same. I'm sure Amsoil will be very good.
