Does anyone use automatic transmission fluid as their power steering fluid? I've heard of some people doing this and I'm wondering if this will work; I guess the principle is the same, hydraulic pressure.
Any ideas?

I believe it says in the manual that, in our cars, you are supposed to use tranny fluid in the power steering system. It states what specific fluid to use (SAE3 or something like this).

Yes dude, ATF is the ONLY fluid to be used in the power st. The manual explicitly says that.

yep, but make sure you read the manual to get the right kind, I forget what it is off hand.

damn...I'm using ps fuild...now what?

^^^it probably won't kill it. But if you want, you can bleed that out and fill with Nissan ATF fluid.

OEM Nissan from the dealer.

any of you guys ever done a FULL PS flush (NOT just by sucking the reservoir), how many quarts of fluids did you replaced?

You just need plain old DEXRON.
for the PS or the A/T same shet.

This is something I need to get at here. The PS fluid is real old in my car and really needs to be changed out. Been having a low humming like noise when turning the steering wheel to the extreme left or right. Is there a drain plug in the system? Chilton manual just barely covers this topic.

I used synthetic in mine, but I only flushed the resovior twice (two weeks apart to let the fluid intermix). You might need a new washer if you decide to drain from below, and there might be problems with getting all the air out of the rack.

pt fluid and trans fluid is the same oil. just labeled different. At my work if u read the motorcraft bottles for at or ps the say they can be switch into any system whether its ps or at. its wierd though they put into to different bottles but then again they are just tryin to make money. ill try to get a picture of the motorcraft label at work this week to show u.
