To do 7A trans fluid change or not??

Quicksilvers

Changing your transmission fluid is a necessity for maintenance on your Z. I change my transmission fluid once every 2 years. You will notice your A7 transmission shifts smoother and more efficiently after you change your transmission fluid. Changing your transmission fluid at least every 30K will help prolong the life of your A7 transmission. I would use any synthetic transmission fluid like Mobil 1 or Amsoil. The transmission fluid capacity of your A7 transmission in your Z is about 10 quarts. You only drain 3 quarts of transmission fluid at a time and the only way you can drain all your transmission fluid is by using a machine like at your local Nissan dealership service department or by removing your transmission from your Z. If you don’t trust yourself or are a novice I wouldn’t recommend DIY. Have the Nissan dealership service department or a reputable shop change your transmission fluid for you.
