SYSTEM FOR CONTROLLING FLUID LEVEL IN A SUMP

摘要

A system for controlling the level of hydraulic fluid between a first and second sump in a transmission includes a valve assembly located within the first sump. The valve assembly includes a valve that is moveable between two positions. The valve assembly includes first and second inlet ports that communicate with the first sump and an outlet port that communicates with the second sump. The second inlet port has an opening that is located higher than an opening to the first inlet port. Hydraulic fluid within the first sump communicates through the first inlet port to the outlet port when the valve is in the first position, and hydraulic fluid within the first sump communicates through the second inlet port to the outlet port when the valve is in the second position.
