How many kilometers does the Atenza need to change the transmission oil?
2 Answers
Atenza should change the transmission oil every two years or approximately every 40,000 kilometers. Transmission oil is essential for keeping the transmission system clean, ensuring it operates normally and prolonging the lifespan of the vehicle's transmission components. Below is some relevant information about the Atenza: Dimensions: The body dimensions are: length 4870mm, width 1840mm, height 1445mm, with a wheelbase of 2830mm, a minimum ground clearance of 162mm, and a fuel tank capacity of 56.2 liters. Power: The Atenza is equipped with a 2.0L naturally aspirated engine, delivering a maximum power of 116kW and a maximum torque of 202Nm. It features a front suspension type of MacPherson independent suspension and a rear suspension type of multi-link independent suspension.
I personally drove an Atenza (Mazda6) for several years. Generally, it's recommended to change the transmission fluid between 60,000 to 80,000 kilometers, as usually stated in the Mazda owner's manual. Why change it? Because over time, the fluid gets dirty or oxidizes, affecting shift smoothness and accelerating transmission wear. For example, in city traffic with frequent stops and starts, the high load and pressure can cause the fluid to degrade faster, possibly requiring inspection as early as 50,000 kilometers. I changed mine at 70,000 kilometers and noticed much smoother acceleration afterward. Not changing it carries risks, like sudden gear shift hesitation on highways, which not only makes driving uncomfortable but also increases repair costs—replacing a new transmission can cost thousands. It's best to have a technician check the fluid during regular maintenance. If the color is clear, it's still good; if it's black or has a burnt smell, act immediately.
