Thanks barkinfool. So both plugs are 10 mm sockets as well. The initial message of this post was the ability to drill an oversized hole in the bottom of the plate thus avoiding taking the plate off when servicing the transmission. Did you find it worthwhile taking the plate off to allow better access to the plugs. The drain plug seems to make sense and easy to service because of drilling the hole. The fill plug seems like a real PITA without removing the plate.
