What kind or brand of automatic transmission fluid i should use in 2002 nissan sentra

IF YOU ARE LOSING THAT MUCH FLUID THEN YOU HAVE A SEVERE LEAK, DO NOT PUT OFF HAVING IT CHECKED BECAUSE RUNNING A AUTOMATIC TRANSMISSION LOW ON FLUID WILL CAUSE SEVERE DAMAGE PRETTY QUICKLY

If your transmission fluid level is proper then you do indeed have tranny hassles. U want to have that taken care of lest you get stranded at worst time.

Dextron II is approved for Nissan as a suitable replacement for Nissan's own Type J transmission fluid.

Dexron 11 went out of production about 1992

If you have to add,common sense tells you
that it is leaking,work on that issue

The brand don't matte,r but the specification does
I would put that question into your search engine
and also check with a dealer,as the current dex is not good
for your vehicle,only the latest GM veh. The Dex/Merc maybe, but the Multi Vehicle
may also be for Asian Vehicles.
Trying to help, but the exact spec I don't know
Also any trans repair shop will happily tell you

a drain and fill is about 3.5 litres.if you pump it out completely including the torque converter,about 10 litres

Manual States - Genuine Nissan Automatic Transmission Fluid "Matic D" , Dextron III , or Mercon is Acceptable . Brand is really a personal preference . cheers .

is it a manual or automatic?if it's manual check clutch.if it is automatic check transmission fluid.

Sorry to say sir but running out of fluid/ transmission oil will definitely fry your tranny.

Ya but if nissan planted filter's in there tansmission's then they would grow,right?NISSAN does not install filter's in the tran's.It is a permanent screen and luckily for people all I have to do is undo the plug from the pan and drain while hot, screw the screw the plug back in and funnel your new fluid back in to the tran from the dip stick tube(my 04 sentra 1.8s 4speed automatic takes 5 quart's but holds 6-type D nissan fluid from dealer,change about every 15 to 20 thousand miles to keep it clean and thin.Remember trans fluid is petroleum and get's hot burn's and thicken's making restriction's on rotating metal).My car has over 90,000miles and shift's perfect
