ZR-1 Net Registry Forums - View Single Post - Transmission/clutch whine when clutch is NOT pushed in.

Paul Workman · 08-01-2013

Mine is a 90 with straight-cut gears, and I have no whine that I'm aware of, before or after installing the Fidanza FW and new PP, TB, and pilot bushing (from AutoZone).

I do know from working with an LT1 car that if the shim plate (LT1 cars) is the least bit other than perfectly flat that whine from the ZF can result and bad things happen to the input bearing.

Well, the ZR-1 does not have that shim plate, but if for any reason the trans is not properly squared with the bell housing, or the housing had been removed or loosened and for some reason askew...?

Bill Boudreau at ZFdoc,com might be able to shed some light. AND, he's the one recommending the Castrol TWS 10W-60 for the ZF.

Like I said...mine doesn't whine when idling/clutch out - FWIW.
