Default Honda MTF - Causes Transmission Noise?

Hi everyone.

My car is at Honda for a new clutch and I'm thinking of doing the gearbox oil while its there. My first choice was MTF like almost everyone here uses with no complaints, only good things to say but the experienced mac there says he thinks it's "too thin" for my gearbox and that it will cause it to be noisy...he recommends a 75W-90 GL4 and says because my car is supercharged it will be better for the gearbox.

Is this true? Has anyone ever heard any noise from their gearbox while using genuine Honda MTF?

the mechanic is smoking something and if s/he's a honda tech, then needs to go back to school.

HONDA MTF was designed for our transmissions in an OEM applcation. HONDA approves it. Believe the engineers at Honda not some random guy with a hoist and bunch of tools.

good luck- my car is not FI so maybe someone else will chime in.

Do NOT let this guy touch your car.

That's what I thought! It is designed for our transmissions so why would it cause any noise?? Thanks for the input man. FWIW the mac said I should go with MTF if I want and he'll fill her up, he's not being vindictive or anything. He's actually really good and received high recommendation from an S2K turbo friend of mine so I went in there asking for this mac by name.

Haha, that bad advice eh? So Honda MTF will be great even in an FI car like mine? Does FI even make a difference to the gearbox's oil requirements?

Forced Induction should not make a difference in what lube the tranny needs. Unless you are making beaucoup HP. In which case you may need a more heavy duty transmission & differential.

As Peter Green would say eh?
Good point. I'm not making so much power that any of my integral components need to be changed/upgraded in terms of mechanical strength. I intend to keep it that way.
So... Honda MTF it is then!

For serious track use it might be good to use something that could handle the heat a bit better than the OEM MTF.
I think the Honda MTF would be rated at around 75W-80 so his recommendations might not be to bad.
But I would probably just replace it more often instead of experimenting.

I'm not tracking yet but even if I did it wouldn't be serious/often. You make a good point though. Maybe that's what he means - OEM MTF is thinner than an off the shelf GL4 75W90. As I said I know he's a good mechanic so I have reason to believe what he says. In this case though, maybe I should take his oil recommendation for the gearbox with a pinch of salt
