It's known as a "Super 10"
9 speed doesn't have a gear splitter, just the range selector.
Grey, both on an Eaton-Fuller and a Mack 18 speed.
No you can not, it is a different transmission. The 18 speed has a splitter for the lower range as well as high range.
Eaton Fuller recommends 50W synthetic. Not sure about other transmission manufacturers.

On all Eaton-Fuller transmissions, the fill plug is on the left side of the transmission. You insert the drive end of a 1/2" socket into it, and turn it counterclockwise to unthread it. That's where the transmission oil goes. Eaton-Fuller recommends you use either 50W synthetic, or 80W if you're going with mineral oil.

Overdrive. The "O" in "RTLO" indicates that, and the transmission in question has a final drive ratio of .73.
I've never heard of an Eaton Fuller 12 speed, nor am I able to find any references to one via Google. I've driven Eaton Fuller 8LL, 9 speed, 10 speed, 13 speed, and 18 speed transmissions - could you be thinking of one of these? IIRC, Volvo marketed a proprietary 12 speed transmission, and Meritor offered a 12 speed automatic, but not Eaton Fuller.
