Methods to determine whether to change the transmission fluid: When you feel that the car's gear shifting is stiff or not smooth, or there are abnormal noises from the transmission, body shaking, or slow acceleration, it indicates that the transmission fluid needs to be changed. After prolonged use, the performance of the transmission fluid will degrade, including reduced viscosity, lubrication, and sealing properties, all of which affect the operation of the transmission and, consequently, the driving experience. Transmission fluid is an oil product that keeps the gear system clean, ensuring the proper functioning of the transmission and extending the lifespan of the transmission components. Most transmission fluids can be used in automatic transmissions available on the market. In fact, each automatic transmission design has different technical requirements. Even the same model of transmission configured in different car models will have variations in torque, weight, speed, and structure. Therefore, the original manufacturer specifies its own dedicated transmission fluid. Different transmission fluids are one of the factors that affect the quality of gear shifting.
