Hi Adam, or should I say good morning,
Im not sure about your sound, but my tranny make a whirring noise too ususally
only after start up and only if I pull the selector to 2...... Ive sat a light
and listened to it thinking what the heck and pushed the selector to 3 and it
disapeared?? Could be a pump in the tranny just pumping things up to
pressure ??? Seems to go away after things heat up.
Good luck at the track.
Later,
Tom

Hello everyone,
As I was backing out of my garage this morning, on my way to another
glorious day at SIR for a much anticipated DE (track testing rear sway bar
steroid treatment) I noticed a faint whirring sound. Did I stop and check
it out? Of course not. I needed to run by my office first, so I thought
I'd check it there in hopes that my prayers to the shark gods along the way
would make the noise go away on the trip out. Well at my office the noise
was still there. So, before I leave for home again, (I'm at my office now)
I thought I'd post to see if anyone would like to take a guess as to what
the problem is.
I know there are million things it could be, and without hearing it
personally it could be anything, but hey, it's 7am on a Sunday so humor me
a little.
The noise is a low toned whirring noise, that increases with engine RPM.
For the life of me, I cannot pinpoint the source of the sound. It seems to
emanate from whatever part of the engine I'm listening to. I am convinced
that there is some kind of audio warping field surrounding the engine that
was designed by Porsche, which requires a factory stethoscope to discern
the source of odd engine noises. No doubt installed to protect shark and
foolish but somewhat mechanically inclined owner from doing harm to one
another.
The sound is reminiscent of a small block Ford with a burnt out water pump
bearing, only much more quiet. (I never understood the need for the weep
hole in those things) I say Ford because I replaced many in my big
brother's armada of Mustangs, but never had to in any of my chevy's (yes,
that's a dig) My water pump was replaced about 4K miles ago, so it should
still be under warranty if that is the case.
So, for my eternal gratitude, and a free can of Spam or chipped beef (your
pick), anyone want to take guess? Also, any ideas on how to a make or
where to purchase a stethoscope so I can do a better job of pinpointing?
Lloyd (Johnston), if you're reading this, hold up on that stroker order, we
may be going for the bulk discount :).
