How often should the transmission fluid be changed for an Audi Q5L?

[LilahLee]

Audi Q5L's transmission fluid should be changed every two years or every 40,000 kilometers driven. When changing the transmission fluid, the oil filter screen should also be replaced simultaneously, as it cannot be thoroughly cleaned and must be renewed. Transmission fluid is a lubricant that maintains the cleanliness of the gear system and serves to lubricate and prolong the lifespan of the transmission components. Relevant information about the transmission is as follows: 1. Introduction: A device that alters the speed ratio and direction of motion. It is used to modify the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under varying working conditions. A gear-driven transmission typically consists of a housing and several gear pairs. 2. Function: During vehicle operation, to adapt to different working conditions, the driving force and speed of the car need to vary within a certain range. However, the existing engine's torque and speed variation range cannot meet this requirement, hence the installation of a transmission.
