Default Re: Fidanzza flywheel and transmission 10W60 oil?

I guess that biggest problem is at highway at cruise maybe 50mph and little uphill comes.. That sound isnt so nice.. So maybe I should get Castrol 10W60 next time if it makes difference to normal GM oil that is used with ZF.

Well, I think we're talking about two different things... The Fidanza/ZF noise at idle is one thing, but noise on the highway - under load ? That doesn't sound so good, and I doubt it has anything to do with the Fidanza under the conditions you describe... Something else is going on there, I guess. I would suggest linking up with Bill B at ZFdoc.com

This started just after Fidanza years ago and I think I have read that single mass flywheel does this with low RPM when there gets more load..

?There will also be some low level growl from the transmission when accelerating lightly in the 750 to 2500 rpm range.?

I completely agree with Pauls statement above. Something else is going on and you need to talk to Bill Boudreau.

I also just recently learned that the Fridanza flywheels are not good to go right out of the box. They need to be drilled and Zero balanced before installation. Im getting ready to install one on my new motor and Polo-1 is getting mine zero balanced. Just FYI

Maybe I was using wrong word. But it makes noise that disturbs me at highway. It isnt drilled/balanced, service just put it there when they changed Centerforce clutch. Problem is at low rpm and goes away if using lower gear.

Something else...

When the transmission is installed, the alignment of the transmission has to be correct, or there can be some noise (and wear and vibration) issues. (Again, visit ZFdoc.com for the specific information. Just a thought.)

Bear in mind that the transmission will "growl" loudly with a single mass on the highway when your lugging the engine.
This is my experience at least.

Mine as well. Accelerating from 1500 rpm to 2500 rpm in high gear under wide open throttle produces a loud "whine" or "growl" in both my single mass flywheel Z's. Marc confirmed that the noise is normal.

Thats good to know. That sound just isnt so nice. Usually helps if rev higher, but problem is worse with cruise that try keep speed something like 50mph or at slow city stop/go traffic.

And 10W60 wont help to this? It helps only at idle?
