Does anyone here have a 1994 (or compatible) owners manual that can take a picture of the service schedule page(s). Specifically, I'm wondering how often the Automatic Transmission fluid is supposed to be changed. Also, does it specifically say "changed" or "flushed"?

Thx

How about the FSM?

I had skimmed the AT manual there but didn't see that info. I'll look again though.

There doesn't seem to be much information posted online about the service schedule. I did find this website, but I don't know how official the info is.

That's the best info I've found so far. Thanks!
FWIW - based on videos I've seen, the question as to whether I should replace or flush is still in the air as the chart says "Replace" but also says "optionally flush"

Flush requires specialized equipment.

Just do a pan drop, overnight drain, filter replacement, and refill. That'll replace about 75% of the fluid. Do twice if you want to be more thorough.

Not seeing what torque to use on the AT pan bolts in the SM, any advice?

I'm not positive on the exact number, but it depends more on the type of gasket. A cork gasket will be a much smaller number.

My process (using a black gasket with a thin layer of rtv on each surface, OR no gasket, just rtv): Start each bolt, spin the socket extension with your fingers (NO RATCHET) until they've all been run down snug. Then do a final criss-cross tightening, starting toward the center of the pan and working your way out, just like a head (don't work AROUND the pan, don't do adjacent bolts in succession).

If you're using a torque wrench, most Nissan transmission pan bolts take 7.9Nm (0.81 kgf-cm, or 70 inch lbs).

However, I've always preferred using my "wrist meter" and watching the gasket. Good lighting and a clear view of the gasket and RTV will tell you all you need to know.

Do you use any thread-lock on the pan bolts?

Oh, and I should be getting a rubber gasket with the filter kit but I've been tolds it can be better to just use a bead of rtv and not to use the gasket. Any opinion on that?

NO threadlock.

I don't hate the rubber gaskets.

This area isn't subjected to pressure or any force whatsoever. Be gentle. The pan lip should remain FLAT.

Thanks so much for the advice.

I was watching this guy's tutorial: https://youtu.be/yb_1wbiPz9g
... and at about 9.5 minute in, he uses silicone paste with the rubber seal. Have you ever tried that and have any opinion?

Yep, he's doing it right. Do what he did and you're fine.
