I am no transmission mechanic, but I have a friend who is, and he has always told me it is better to have a hair too little than a hair too much oil. His explanation is that if the fill level is too high, the trans can whip the oil. If this happens, it can add air to the oil, and cause the pump to cavitate. I dont know if this is true, but I do know that cavitating a high pressure pump will eat it in no time.

If the level is only a very little above the line, when hot, it should not be a problem. A pint or more over may cause cavitation. ALso I believe that the fluid level will show higher when the engine is NOT running, as the fluid is not being pumped thru the system, and some has drained back into the pan.
