Low Transmission Fluid Your automatic transmission relies on hydraulic fluid pressure to operate. In a modern, electronically controlled automatic transmission, shift solenoids control the flow of transmission fluid. In older non-electronically controlled transmissions, shifting was controlled by shift valves, but the idea is the same.
