Just curious to see if anyone uses Amsoil fluid in their transmission and differential. I have a few bottles of Amsoil transmssion fluid and gear lube left behind after I sold my Jeep.
I read the manual and it looks like the transmission fluid is compatible but I would like to find out what grade of gear lube is the most optimum. The manual states 80-90. I have 75-140 gear lube.

Please advice.

Thanks in advance.

Stick with the 80-90(75-90) grade the manual calls for. In addition, make sure you use the correct GL spec. Some call for GL-4, others GL-5. If you have a limited slip differential, then you want a gear lube with friction modifiers to maintain the limited slip function. More of an issue with syn lubes. Some products claim full compatibility, others don't.

dave and xtoy - in other words, read the label

gear oil

I have heard of Nissan dealers switching to 75-140 syn for the Titans rear end to help prevent future failures. There is not any limited slip functions in the Armada rear end, just an open diff. As far as the tranny, IMHO I would stick with OEM Nissan for warranty purposes if nothing else.

This is correct. After many Titan rear end problems Nissan changed the fluid specs to synthetic 75-140. Nissan is very clear about the transmission fluid specs. Our transmissions require a special fluid. If you use a fluid not approved by Nissan it will void your warranty. Some makers of transmission fluids may say that their product meets Nissan specs (and they may), but at this time I don't think Nissan has approved any fluid other than the Nissan brand.

Thanks all for the info. I will stick with OEM fluid for now. Looks like I will have a few bottles of Amsoil to give away.

I have a 2005 SE OR and it has a limited slip rear. Not sure where you heard the Mada only offers an open diff. I'm running Mobil1 75/140 with no problems. I like Amsoil as well.

Nope, ABLS

You (we) have what is called ABLS = Active Brake Limited-Slip Differential.

This description is taken verbatim from the Armada sales brochure;
ABLS
"It senses wheel-spin while accelerating, and automatically reduces engine output and brakes a slipping wheel(s), diverting power toward the wheels with greater traction."

The differential is open, the brakes slow down the spinning tire.
