Great information, thanks a lot!smj999smj wrote:I was a Nissan Master Tech until I left them in 2003 and rebuilt a number of Nissan trannies in my 16 years with them, until Nissan reman. units finally made it a rate occurance to rebuild a trans. Nissan transmissions do not use a filter, just a screen. Nissan's thinking is that if there is enough debris in the fluid to clog a filter, then the trans is on the way out and needs an overhaul, not a fluid and filter replacement. Your ATF is synthetic and under normal circumstances, will usually not require frequent servicing. That said, I would still recommend at least a drain and refill every 60000 miles; I do mine every 30000 mi. If by "flushing," we are referring to the fluid exchanging machines currently used by most dealers and many independants, they are not hard on the trans. They incorporate a tank with a bladder system. The machine is filled with about a case of new ATF and the lines are hooked between the radiator cooler fitting and the cooler hose. When the engine is started, the old fluid goes into the tank and pushes against the bladder, which forces new fluid into the cooler line and back to the trans. This system does a much better job at getting most of the fluid replaced. The big key is making sure the correct ATF is used. As far as fluid type, you can't go wrong using genuine Nissan ATF type "S." It is expensive, though. Personally, I use Valvoline Maxlife ATF in my 06 LE and my friends 08 SE. I've been using this for over a year in each of them and no problems or differances in performance in either one.
