How deep water can cause transmission fluid ingress?

[SanGeorge]

Transmissions generally do not take in water as they have certain IP protection ratings. The wading depth that typically causes issues is when water rises above the vehicle's air intake, entering the intake tract and eventually the cylinders, leading to engine stalling and immobilization. Below is an introduction about transmissions: 1. Overview: A device that changes speed ratios and direction of motion. Used in automobiles, tractors, ships, machine tools, and various machinery to alter torque, speed, and motion direction transmitted from the driving shaft to the driven shaft under different working conditions. Gear-type transmissions generally consist of a housing and multiple gear pairs. 2. Functions: Alter the gear ratio between the engine and wheels, allowing the engine to operate under optimal conditions while expanding the torque and speed transmitted to the drive wheels, achieving various speeds; enabling vehicles to reverse; providing neutral gear position.
