How do I drain 2004 Nissan Quest transmission fluid?

Answer 1

First, beware of the type fluid used, especially if the tranny is still under warranty. That said, this is easy. On the front side (toward the radiator/front of van) of the transmission (which is the driver side half of the engine/tranny "unit"), at the very bottom, is a large plug with an allen wrench inset. As I recall, I used a 10mm allen wrench. Have your pan ready, as it comes out full force, and will start flowing before the plug is all the way out. Additional hints: 1) Get a new washer for the plug. Cheap insurance against leaking. 2) Be very careful not to over-torque it when reinstalling, as it is an aluminum housing, so it's easy to strip. 3) If you use a non-Nissan fluid, keep in mind that some are pure synthetic and some are "blends" (e.g., Valvoline Maxlife, which I have used in other applications). If it has always had pure synthetic, then most mechanics will recommend sticking with pure synthetic. 4) Use jack stands (unless its on a rack/ramps, of course)! Happy motoring!
