Where does all hydraulic flow begin?

Explanation:
All hydraulic flow in a transmission starts from the fluid reservoir. The oil stored in the sump or pan serves as the source of hydraulic fluid. A pickup draws that fluid from the pan into the transmission pump, which then pressurizes and routes it through the valve body to operate clutches, bands, and other hydraulic components. The pump and its type (like a vane pump) are essential to move the fluid, but the starting point of flow is the oil pan. The torque converter sits in the hydraulic path but does not initiate the flow.
