When do you know if you need to change the ATF. I have received some confusing information about this.
1. From the manual, just for the fluid level during "N". Also from the maintenance schedule, inspect at each interval, replace after 105000 miles.
2. I went to a Valvoline instant oil change place.. While doing the oil change, they also check the ATF and said my car need the ATF change. I have 55000 miles on my car. He shows that ATF should be pink, while mine is a bit brown. Is color the identifier if we need to change the ATF?
3. My sonata start to make a very small vibration on the highway. As the driver, I could feel it. But my wife, as the pessenger, can't really feel it. Is this saying need to check the ATF fluid?
4. A little bit off the Hyundai topic, I also had an old Audi. It's Audi A6 1996. I called 2 dealers near my home about ATF change. To my surprise, one of them said Audi ATF is lifetime fluid. No need to change it ever. Is there such a thing? BTW, the other dealer gave me a price quote.
