Default Name that noise!!!

Alrighty,

I've had a high-pitched/whistling noise occur while my car is cold, since I had the tranny fluid changed.

By cold:
I mean it has been sitting for a while.

The noise seems to come from right in front of the driver seat in the bay. This led me to thinking the belts, however they all check. I had someone look at it and they said that it was the bearing for the crank to engage. However, I think this was a bunch of bs as I had never heard the noise before the fluid change. Anyways the noise only occurs above ~40mph and goes away after about 2 minutes.

Anyone else have this noise and symptoms?

Happens to me in the startup when it was very cold. it goes away after car warms up, so shouldn't be a big deal.

Looks to be common:

Thanks man. I searched similar noises but could only find topics regarding electrical grounds.


EDIT: So it was the pilot bushing. Must of happened while being lifted.
