How to change AT Tran Fluid?

Sep 28, 2003 7 Replies

I've changed oil, radiation fluid, drive axles, struts, but never transmission fluid.



Have a 02 Sentra, and would like some advice on how to change the tranny fluid. Is it as simple as opening a plug and replacing it? Or is there a lot more involved? The fiance does quite a bit of city driving and I just want to do some preventative maintenance.



Thanks in advance

If it's an automatic, you probably need to remove the pan. I've never seen an automatic that had a drain plug. Also there is a screen or filter that needs to be changed or cleaned. And the pan usually has a magnet to collect metallic debris in the fluid and that needs to be cleaned.

Most Nissans from about 1990 on with AT have drain plugs. Of course, what would a fry tech know about that?

Also there is a screen or filter that

99% sure it has a drain plug.

You might have to refill via dipstick.

Just remember avoid dust at all cost! dust can kill a AT box very quickly. If > I've changed oil, radiation fluid, drive axles, struts, but never > transmission fluid.

also check the nuclear fuel cell and replace the atomic synchronizer belts

lol

And don't forget those plasma relays!

Damn forgot these ! thanks for the reminder ! running with old relays could have caused premature wear of the piston return springs
