How Often Should the Aisin 6AT Transmission Fluid Be Changed?
2 Answers
It should be replaced after approximately 3 years or around 60,000 kilometers of driving. If the vehicle frequently operates in congested environments, the transmission fluid can be changed at around 50,000 kilometers. For vehicles often driven on highways, the transmission fluid can be replaced at around 80,000 kilometers. Additional details are as follows: 1. Transmission: A transmission is a mechanism used to alter the speed and torque from the engine. It can either fix or change the gear ratio between the output and input shafts, also known as the gearbox. The transmission consists of a gear transmission mechanism and a control mechanism, with some vehicles also featuring a power output mechanism. Most transmission mechanisms use ordinary gear transmission, while some employ planetary gear transmission. Ordinary gear transmission mechanisms typically involve sliding gears and synchronizers. 2. The stepped transmission is the most widely used type: It utilizes gear transmission with several fixed gear ratios. Depending on the gear system used, there are two types: fixed-axis transmissions (ordinary transmissions) and rotating-axis transmissions (planetary gear transmissions). Passenger cars and light to medium-duty trucks usually have transmissions with 3-5 forward gears and one reverse gear, while heavy-duty trucks with combined transmissions may have more gears. The number of transmission gears refers to the number of forward gears.
I usually pay close attention to car maintenance, especially when it comes to the transmission. When should the Aisin 6AT transmission fluid be changed? Generally, you should refer to the owner's manual recommendations. My car's manual suggests changing it every 60,000 km or 4 years, but if you drive aggressively, it should be done earlier. If you don't change it, the fluid will degrade and get dirty, affecting shift smoothness, and in the long run, it could even damage the transmission, leading to costly repairs. I make it a habit to regularly check the fluid condition—if it turns black or smells burnt, I change it immediately. In daily driving, stop-and-go traffic in the city causes more wear, while highway cruising is gentler. Regular maintenance not only saves money but also keeps the car running smoothly. Don’t delay it too long, or you might hear clunking noises when shifting, which can be dangerous on the road. In short, spending a little on fluid changes is much better than replacing the entire transmission.
