It is a pita to drop the drive shaft when lying on your back in the heat. I'd put it on a flat bed. It's much easier. I read somewhere that the 722.xx transmissions have a couple of pumps to circulate fluid and can be towed flat.

Confirm this because it's been a long time since seeing that info and I'm not sure where it came from.
