Yes you could. If the trans is overfilled, though I don't think a half quart over would do it it, the rotating parts will whip the fluid into a foam, and that also causes quite a bit of heat. Foamed fluid does not transmit pressure well, so this could also have made the torque converter clutch slip, which would create A LOT more heat.
