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. If the shift solenoid is faulty, then the fluid won’t be routed to the desired shift actuator.
