I *had* the same thing happen to my aveo, if you have the manual it tells you the right amount/type to put in for the transmission. I drove mine for about 3 minutes and the same thing happened, changed it again right on the side of the road, the tranny shifted a bit rough for the next couple of miles but it has been perfect for the last 20k miles or so, they are strong. On the other hand, I blew my valve cover gasket, but no other damage or problems have occurred.
