Overfilled Transaxle

Call me a dumb a** if you want, but I changed the transaxle filter yesterday on my 03 malibu and when I was done I added 10 quarts of dextron 3 because the manual says that capacity is like 9.7. Anyway I got to thinking about it this morning and realized that I had to of overfilled it because of the amount left in the torque converter. Now I have driven it 75 miles since I changed the fileter, but my question is how much damage could I have done by overfilling it and driving this distance? It is shifted fine when I drove it, but should I be expecting the worst?

I did the same thing, just pull the plug on the right side of the trans, and let the surplus drain with car level and shifting thru gears.
