Will the engine malfunction indicator light come on if there is slight water ingress? Automatic transmission water ingress repair. During summer with heavy rainfall, vehicles frequently wade through water, increasing the frequency of car washes. Additionally, air conditioning is often used for cooling, which may lead to water ingress inside the automatic transmission. Carelessness can result in automatic transmission malfunctions. The repair cost varies depending on the extent of water ingress in the automatic transmission. Relevant information about the transmission is as follows: Introduction: A device that changes the speed ratio and direction of motion. It is used to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. A gear-driven transmission generally consists of a housing and several gear pairs. Function: While driving, to adapt to different working conditions, the vehicle's driving force and speed need to vary within a certain range. However, the existing engine's torque and speed variation range cannot meet this requirement, hence the transmission is installed.
