The Mazda 3 transmission fluid should be changed every 60,000 kilometers. Below are the detailed steps for changing the transmission fluid: 1. Fluid Replacement Methods: Generally, you can choose between manual fluid replacement or transmission fluid replacement. Manual replacement is quicker but less thorough, as it only removes part of the old fluid from the tank and cannot completely drain it. Transmission fluid replacement, though more time-consuming, can remove at least 85% of the old fluid. 2. Replacement Precautions: During the replacement process, it is essential to operate with the engine running. Since automatic transmission fluid replacement must be performed while the vehicle is warm, the car should be driven for at least 20 minutes before replacement. Start the engine and shift through all gears from P to N, D, L1, L2, etc., before beginning the fluid replacement. 3. Replacement Interval: The fluid should be changed every 40,000 kilometers, with a maximum interval of 60,000 kilometers. Failing to replace the transmission fluid on time can directly impact the vehicle's performance, fuel efficiency, and even the lifespan of the transmission.

As a veteran mechanic with over a decade of experience, I must remind you not to neglect the transmission fluid maintenance for your Mazda3 (Axela). Generally, the owner's manual recommends changing it every 60,000 to 80,000 kilometers, or approximately every 4-6 years, depending on your driving habits. If you frequently encounter city traffic congestion or drive on mountainous roads, the transmission fluid deteriorates faster, possibly requiring replacement as early as 50,000 kilometers. Failure to change the fluid on time can cause it to thicken and become contaminated, leading to rough gear shifts or internal component wear, which could cost thousands to repair. I've seen many owners delay replacement beyond 80,000 kilometers, only to end up with a completely burnt-out transmission system. It's best to regularly check the fluid color—fresh fluid is transparent with a reddish tint, and if it appears cloudy, act promptly. When changing the fluid, use the manufacturer-recommended type that matches your Mazda3's AT or MT transmission model to avoid issues from using inferior products. Safety first—don't risk major problems for minor savings.

I've been driving my Mazda3 for five years, and firsthand experience with transmission fluid is crucial. The manual recommends changing it every 60,000 kilometers, but since my driving style is a bit aggressive—I love speeding on highways—I opt to change it every 50,000 kilometers instead. Spending around 200 yuan on the fluid is totally worth it. After the change, gear shifts indeed feel much smoother, acceleration is silkier, and fuel consumption drops slightly. A friend waited until 70,000 kilometers to change theirs, only to end up with a transmission warning light and a repair bill in the thousands. When changing the fluid, find a reliable repair shop—it takes just 20 minutes, no need to dismantle the transmission; just drain and refill. Driving habits also affect fluid longevity—avoid hard braking and sudden acceleration to keep the fluid in good condition longer. Make it a regular maintenance checklist item for peace of mind, convenience, and safety. Don’t wait for problems to regret it!

Maintaining a car is like managing a household, and changing transmission fluid requires careful budgeting. The standard recommendation for the Mazda3 (Axela) is to replace it every 60,000 kilometers or 5 years, costing around 400-500 RMB. Since I drive steadily for daily commutes without sudden braking or overloading, stretching it to 70,000 kilometers isn’t a major issue—but don’t ignore warning signs just to save money. Aged fluid accumulates impurities, degrading transmission performance, and delaying too long could lead to repair costs exceeding 10,000 RMB. Set a mileage reminder, such as having a technician inspect the fluid condition during every 50,000-km service. If the color darkens or there’s an unusual odor, act immediately. Prevention is cheaper than repairs, and safe driving always comes first.
