Got an easy question. I'm wanting to change out my transmission fluid tom. Is it ok to mix 1qt redline mt90 75w90w with 2qt oem 75w85w fluid?

 

Probably OK, but why?

 

I herd from other members if its just redline it is still notchy. So i'm figuring that if I put in oem and redline it might work well together.

 

I've got the Redline MT-85 in mine, and it shifts like butter. But, I'm in a warm climate, and have the CD009 gearbox. YMMV.

 

I'm in TN so it varies temp wise... But ill just see how it goes tom...

 

I have Motul and for the first 20 miles or so shifting is death.now that it's warmed up a bit it's not as bad but still noticeable till heated up

 

Redline in mine. Cold is very notchy but it's short lived. By the time I leave my neighborhood it's shifting smooth as silk.

 

Live in Colorado and used MT85 in both my street and track 350Zs. Cold weather, hot weather- doesn't make a difference if you know how to heel/toe downshift and rev match.

 

People don't know and don't care to know how to rev-match or heel/toe downshift and I'm one of them. With today's (even in 03) technology I shouldn't have to and if you run factory fluid you don't have to know or care. Joys of modern technology.

 

That's ridiculous, and I hope you're kidding. The purpose of knowing how to rev-match your shifts (up and down) is to maintain the balance of the car. You will also have far less wear and tear on the drivetrain components. If one chooses not to learn, at least on a street-driven car, you'll pay the price in repair costs, and in a race-driven car in lap times.

 

Yeah to drive on the street you definitely do not need to know and do it 100%


I only do to make cool sounds. On track though that's 100%
