Hi
I need a automatic transmission fluid service and choose "I have part" and then saw the part requirement for the ATF fluid needs 1QT x 8. But according car menu, it should be 3.7QT. The only concern is how much automatic transmission fluid to switch for 2007 Camry 2.4L?

My car has 120000 miles.
My car has an automatic transmission.
