I am going to be doing my trans and diff fluid soon, and just wondering what everyone is using. I dont know if i should give redline 75-85 a try or use nissan fluid?

LMK what you guys think.. and i have to go by nissan or infiniti to get the washers.

I did Redline MT-90 in the trans and 75W90 in the rear at 30k miles, at 45k now with no issues. I hear Nissan has some special sauce for the tranny but I haven't had any issues with MT-90.
Don't waste your money replacing the copper crush washers, you can reuse the old one with no worries...

As long as its GL4 in the MT, and GL5 in the diff.
Avoid GL5 in the MT.

I did royal purple high pressure 75w90 in the rear dif. Was a little expensive, but I haven't had any issues at all.

Redline reccomends MT-85 for our transmissions.

Wasn't available when I did my trans but I would definitely use it next time..

How is buying a new copper washer for our car really a waste of money?

Unless the old one is damaged it can be reused...

Was kinda wondering the same thing. I mean they're REALLY cheap...like a few bucks.

Do not use MT90 Use MT85. People use to blend two different types to get the 85 until redline finally came out with mt85.

From what I'm understanding, you're not supposed to change it cause it's a sealed unit or some crap. Idk if I'm cool with that....but there was a big discussion last week about it.
