And the filler plug is on the passenger side (American cars, not British). You will find the easiest way to fill it up properly is to put it up in the air, with each wheel level, then fill it up until it dribbles out the hole. Then use a small plastic tube to syphon just a bit off the top. Then you can double check it with your little finger. That really is the easiest way. And ignore what anyone tells you if they suggest using anything but GM Synchomesh #12345349. You need about 5.3 pints for a full change out. I use a 9/16" Pipe Plug Socket, but a wrench will do. Use an anaerobic sealant on the plug threads, torque it to 20 ft/lbs, and then mark it with a little Torque Seal just to be thorough. It actually is one of the more easy tasks on these cars.
