Can You Still Drive with a Damaged Transmission Valve Body?

You should not continue driving the car after the transmission valve body is damaged. Here are more related details: Cause Analysis: 1. A damaged transmission valve body may experience jamming. If leakage occurs, it can cause gear shift shocks during the transmission's shifting process, significantly reducing shifting efficiency and also leading to a decrease in the car's power. 2. The transmission valve body is a hydraulic control unit. During operation, the spools on the valve body move left and right to change the direction and pressure of the hydraulic oil, enabling the transmission to shift automatically. If the valve body is damaged, jamming or leakage can cause gear shift shocks. It's worth noting that the spools on the valve body are controlled by the electronic control unit via solenoid valves. 3. Damage to the transmission valve body is more common in automatic transmissions. Automatic transmissions, as opposed to manual transmissions, allow the car to shift gears automatically based on driving speed and engine RPM. Currently, the most common types of automatic transmissions used in cars are hydraulic automatic transmissions (AT), continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions.
I strongly advise against driving the car because the transmission valve body is faulty. The vehicle might suddenly fail to shift gears or get stuck in a certain gear, which would be extremely dangerous, especially on the highway. The transmission is like the brain of the car, and the valve body controls the shifting action. If it fails, the transmission may slip or malfunction. I once encountered a similar issue during a long-distance drive. I managed to drive a few kilometers, but the entire transmission ended up being ruined, costing me over ten thousand yuan to repair. Park the car and check for symptoms, such as shaking during gear shifts or any unusual noises, and immediately contact a repair shop for inspection. Regular maintenance of the transmission fluid can prevent such problems, but don't risk driving—safety first.
Never push your luck and keep driving. When the transmission valve body fails, the car may jerk severely during startup or gear shifts, affecting control. From a cost-saving perspective, forcing it to run could turn a minor issue into a major one, such as damaging other components, easily pushing repair costs up to thousands. Although replacing the valve body is expensive, it's better than having the entire transmission scrapped. I've encountered a similar situation before—immediately pulled over to check if any warning lights were on, then called a tow truck to a professional shop. Also, a quick tip on car habits: regular transmission fluid changes can extend its lifespan, but for now, don't drive to avoid greater damage.
