Abstract
A fluid management system for a drivetrain includes a first reservoir, a second reservoir, a main suction line, and a second suction line. The first reservoir is positioned in a lower portion of a transmission. The first reservoir has a preselected fluid level. The second reservoir is positioned in a lower portion of the transmission. The second reservoir is separated from the first reservoir by a barrier having an opening. The main suction line has an opening positioned in a lower portion the first reservoir below the preselected fluid level. The second suction line has an opening positioned in a lower portion of the second reservoir.

A fluid management system for a drivetrain, comprising:
- a first reservoir positioned in a lower portion of a transmission, the first reservoir having a preselected fluid level;
- a second reservoir positioned in a lower portion of the transmission, the second reservoir separated from the first reservoir by a barrier having an opening;
- a main suction line having an opening positioned in a lower portion of the first reservoir below the preselected fluid level;
- a second suction line having an opening positioned in a lower portion of the second reservoir;
- and
- an overflow tube positioned in the opening of the barrier, the overflow tube having a first end positioned above the opening of the main suction line and a second end in fluid communication with the second reservoir, the first end of the overflow tube positioned at a center of the first reservoir, the first end of the overflow tube positioned at the preselected fluid level in the first reservoir, and the first end of the overflow tube positioned higher than the second end.
