Has any one changed their Automatic Transmission Fluid and Transfer Fluid? If yes, Can you share some of your experinces or how to dos with us? Is Transfer case only a 4X4 thing? Thx.

Only 4X4's have a transfer case. The transmission fluid is Nissan J type, and at this time is the only one approved by Nissan. Use of an unapproved fluid will void the warranty on the transmission. Follow the Nissan fluid change schedule, and it probably would be best to have your dealer change the fluid.
