How often should the Mazda 3 transmission fluid be changed?
1 Answers
Mazda 3 transmission fluid should be changed every 60,000 kilometers. Failure to replace the automatic transmission fluid in a timely manner will directly affect the vehicle's performance, fuel consumption, and even the service life of the automatic transmission. The following points should be noted when changing the transmission fluid: 1. Fluid Replacement Methods: There are generally two methods for changing the fluid—manual replacement or transmission fluid exchange. Although manual replacement saves time, it has a drawback: the fluid is not completely replaced. Typically, manual replacement can only drain part of the old fluid from the tank and cannot thoroughly remove all the old fluid. On the other hand, a transmission fluid exchange, though more time-consuming, can remove at least 85% of the old fluid. 2. Replacement Precautions: When changing the fluid, owners should note that, regardless of the method, the operation must be performed with the engine running. Since automatic transmission fluid replacement needs to be done when the vehicle is warm, the car should be running for at least 20 minutes before the replacement. During the fluid change, start the engine and shift through all gears from P to N, D, L1, L2, etc., back and forth before beginning the fluid replacement. 3. Replacement Interval: Many owners often wait until the transmission fluid deteriorates before considering a replacement, and some even neglect the type and quality of the fluid during the change. These practices can cause damage to the transmission and even shorten its lifespan. If the vehicle manual does not specify a replacement interval, it is recommended to change the fluid every 40,000 kilometers. The maximum interval should not exceed 60,000 kilometers.
