Much like a heart, the transmission fluid pump pumps transmission fluid throughout the automatic transmission to lubricate the metallic moving parts, such as gears, within the mechanism to prevent wear or to slow it. It also pressurizes the transmission fluid to increase the effectiveness of the hydraulic system that sets in motion the valves within the valve body.
