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.
A Fuller 13-speed Road Ranger transmission typically weighs between 500 to 600 pounds (approximately 227 to 272 kilograms). The exact weight can vary based on the specific model and configuration. These transmissions are designed for heavy-duty applications, contributing to their substantial weight.
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.
The oil capacity of a Fuller 13-speed transmission typically ranges from about 12 to 15 quarts, depending on the specific model and configuration. It's important to refer to the manufacturer’s specifications for the exact oil capacity and type, as it can vary slightly between models. Regular maintenance and proper oil levels are crucial for optimal performance and longevity of the transmission.

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.
