Can You Continue Driving with a Faulty Transmission Valve Body?

[Sean]

You should not continue driving if the transmission valve body has issues. A malfunctioning transmission valve body can cause sticking phenomena. If leakage occurs, it may lead to gear shift shocks during transmission operation, significantly reducing shifting efficiency and causing a decline in the vehicle's power output. The transmission valve body is a hydraulic control unit where spools move laterally to alter hydraulic fluid direction and pressure during transmission operation, enabling automatic gear shifts. Valve body failures are more common in automatic transmissions, which were developed as an alternative to manual transmissions. Vehicles equipped with automatic transmissions shift gears automatically based on driving speed and engine RPM.
