How many kilometers does the BMW 5 Series transmission fluid need to be changed?
1 Answers
It is recommended to change the transmission fluid of the BMW 5 Series at around 60,000 kilometers. Over time, the viscosity of the transmission fluid becomes "thinner," which can lead to high temperatures. This not only accelerates internal mechanical wear but also reduces lubrication and sealing performance, resulting in symptoms such as gear shifting issues, hesitation, delays, jerking, and poor smoothness. Relevant information about the transmission is as follows: 1. 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. 2. Function: During driving, to adapt to different operating 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 need for a transmission.
