Hey Scotty I have a 06 V6 Hyundai Sonata automatic transmission 160k miles on it. When I drive it between 1st and 4th gear it has a low wine that sounds like a spooling super charger as if something is spinning up. But once it’s in 5th gear it stops and sounds normal. Wondering what this could be or if it’s normal please help. Vehicle still shifts good and no notable problems with the car so far.
