I have a 03 350 base with the nismo Lsd. It is time to change my diff and tranny fluids What weight fluid is best for these applications. I would like to use redline fluids.

 

[steve350z]

transmission API GL-4, SAE 75W-85

differential API GL-5, SAE 80W-90

Easy one. Royal Purple Max-Gear. It is safe for both the tranny and the Nismo Rear end. :cheers:

 

[dragonslayer5425]

how much to get 4 qts?
What viscosity is royal purple?

 

[lovetoclown]

It's about $8 bucks a quart. Not sure what the exact viscosity is. The Max-Gear is just one weight.

 

[dragonslayer5425]

I ment to say how many quarts do I need?

 

[steve350z]

tranny takes 3 1/4 quarts and the diff takes 3 pints

 

[jetpilot718]

At what intervals should we be changing our tranny and differential fluids? IE, how many miles should I wait until?

 

[craigy]

Is there a tranny filter that needs replacement along with the fluid ??
Thx!
Craig

[steve350z]

the fill plug is where you drain it. it is located on the drivers side

 

[n8vz]

be sure to get new washers do you don't develop a leak

Royal purple 75w-90... i've talked to a few other owners and this is what they are using in both rear end and transmission. the only person who i can find 80w-90 is amsoil for the rear end... I don't like the idea of having to do the 50/50 MTL/MT90 for the redline fluid. I've used royal purple in the past in 4wd trucks and stuff and it has worked great and improved shifting.
