At what water level does the transmission get flooded?

[DelMaggie]

Here are detailed explanations of two scenarios where water enters the transmission: 1. Water level exceeds two-thirds of the wheel height: When water surpasses two-thirds of the wheel height, the probability of transmission flooding ranges between 80% to 90%. If the water reaches the dashboard level, the transmission is 100% flooded. 2. Water splash during oncoming traffic: Excessive road water can create splashes that hit the vehicle body, leading to transmission flooding. 3. Consequences of flooding: When water enters the transmission, the performance of transmission fluid is severely compromised. Not only is the lubricating capability impaired, but the power transmission efficiency also decreases, causing clutch slippage. Subsequently, rising fluid temperature may generate steam or even cause boiling of the oil-water mixture. These viscous substances can accumulate in the valve body, causing blockages that affect the transmission control system.
