Will Water Enter the Transmission When Driving Through Water?
2 Answers
Water can enter the car's transmission when driving through deep water. Here are the specific details: 1. Wheels: If the water level exceeds two-thirds of the wheel height, there is an 80% to 90% chance of water entering the transmission. 2. Dashboard: If the water reaches the dashboard level, the transmission is 100% flooded. Additionally, while driving through water, splashes from the road can also lead to water entering the transmission. Water primarily enters through the transmission's vent hole, as it is not completely sealed, allowing water to seep in directly.
I've been driving for many years and have encountered several flood-prone sections. Shifting gears can indeed cause water to enter the car's interior. Manual transmission cars have a gear lever directly connected to the transmission. When wading through water, if the water reaches a certain depth and the gear shift action is too forceful, water can seep into the transmission oil through the gaps around the lever. Over time, this can cause the gears to rust or wear out. I remember once driving through a puddle after a heavy rain, and after shifting gears, the car started shaking abnormally. When I took it to the mechanic, he opened it up and found it full of water stains. It cost me several thousand dollars to repair the transmission. Although automatic transmission cars have button-style gear shifts, they can also let water in if the air intake holes are poorly designed. The most critical factor is the water level—if it's more than half the height of the wheels, don't take the risk. Maintain steady throttle and avoid shifting gears while driving through. There are many risks when wading through water, including water entering the engine or causing electrical shorts. In short, the safest option is to avoid driving through water. If you must, drive slowly at a steady speed without shifting gears, and check the car's condition as soon as possible afterward to prevent major issues.
