an rtlo18913a trans means it can handle 1850 ft lbs of torque,it is cooled by engine coolant ,and it is a double over drive with .74 high gear
No, 10 speed does not convert over. You would need to get a truck with either a 13 speed, or a 9C transmission (which is convertible).
Keep rpm between 1400 to 1600
No you cannot change a 13 to a 18 speed, however you can change a 18 speed to a 13 speed just by changing the shift knob.
You'd be in the 18,000 lb. range.
No you can not, it is a different transmission. The 18 speed has a splitter for the lower range as well as high range.
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.
No. Unless you have a "C" transmissions (e.g., RTOC, RTLOC, etc.), it's not convertible. A 10C transmission doesn't convert to a 13 speed - a 9C transmission does. A 10C converts to a 15 speed, which remains essentially a 10 speed with five deep reduction gears.
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.
................2...............4---------------6/7...............10/11 1..............3...............5---------------8/9------------12/13 ................low range......................high range with splitter on each gear
Heavier weight oil might work in warm climates but I wouldn't put it in north of Texas. Eaton specs 50 wt. synthetic in their 18 speeds.
No such thing. Are you asking about a Super Ten transmission, or a 13 speed transmission?
