How many quarts of transmission cvt ns-3 fluid do I need to change my transmission fluid?

Hi! This is Bo with Car Genius at RepairPal! Glad the Sentra is on it's way to being back on the road! The max amount of CVT fluid is 7.29 quarts. You could pull the transmission drain plug just to see if there is fluid and if there is, what condition it's in. If it's at dark or low it could mean a new CVT is in order. You could try to fill it to the correct amount and see what happens! Good luck! If you have any other questions feel free to give us a call at 877-913-1554! We'll be happy to help or find you a certified shop in your area!
