The transmission fluid of the Reiz should be changed approximately every two years or 40,000 kilometers. The method for changing the transmission fluid is as follows: 1. Lift the car and use a suitable screwdriver to remove the inner and outer casings of the transmission, allowing the waste fluid to drain out. 2. Remove the oil pan gasket and clean the surrounding dirt. 3. Wipe the surface of the replacement parts clean and add the new transmission fluid. The Reiz features a double-wishbone front suspension and a multi-link independent rear suspension. It is equipped with a 3.0L naturally aspirated engine, delivering a maximum horsepower of 227 PS, a maximum power of 167 kW, and a maximum torque of 293 Nm, paired with a 6-speed automatic transmission.

Regarding the transmission fluid change, I've been driving a Toyota Mark X for ten years. Generally, it's recommended to replace it every 60,000 kilometers or 4 years. However, it depends on driving habits. If you frequently drive in city traffic with low speeds or drive a lot on mountain roads where the fluid temperature tends to rise, you might need to change it as early as 50,000 kilometers. Long-term neglect can lead to fluid degradation, causing rough gear shifts and increased noise, and repairs could cost thousands—totally not worth it. Regular maintenance can extend the transmission's lifespan. During each service, I have the technician check the fluid quality. If it's discolored or has a sour smell, I address it immediately. For short city commutes, I keep track of the mileage and head to the dealership as soon as I exceed the limit.

Speaking of the transmission fluid for the Reiz, I had no experience when I first bought the car. The technician at the 4S shop told me that automatic transmission fluid should typically be changed every 60,000 to 100,000 kilometers or every 5 years, whichever comes first. If you drive mostly on highways where temperatures are stable, you can stretch it to 70,000 kilometers. However, in congested city driving, the fluid pressure fluctuates, and wear is faster, so you should change it earlier. I perform a simple self-check every 10,000 kilometers by pulling out the dipstick to check the color—clear and bright is good, but dark and murky is a warning sign. In terms of saving money, skipping timely changes can lead to major repairs and unnecessary expenses. Now, I’ve developed a habit of lubricating components during each fluid change to keep the car running smoothly.

I think changing the transmission fluid can save a lot of money. The Reiz manual suggests replacing it every 60,000 kilometers or so. If you exceed this interval, the fluid thickens, shifting becomes less smooth, fuel consumption increases, and it may even damage the gears. Don't delay too long, especially if you frequently drive on mountain roads or in heavy traffic, as the fluid can overheat easily, so consider changing it earlier at 50,000 kilometers. You can simply check the fluid's condition yourself, and if you notice any contamination, address it promptly. Regular replacement costs little, helping you avoid thousands in transmission repairs.
