I have a 2008 Nissan Altima S. I went to change my CVT fluid the other day, got under the car and low and behold there was no drain plug. After some research I found out that not all of the pans came with plugs. I ordered a new pan with a drain plug thinking that will make it easier in the future to change my fluid. However, I only ordered 6 quarts of fluid to do the initial drain and fill. Is that going to be enough fluid or do I need to get more?
