Whining Noise

Whining Noise
I have an intermittent whining noise, usually in 2nd, 3rd, 4th gear. Comes and goes. Can hear it when accelerating and changes with gear change. Sometimes it's noticeable at deceleration. I think my PS pump is on it's way out. Could that be it or does it sound like a tranny issue? Please advise...

I think I also have a whiny PS pump, but it's been better now that I did a few suck-n-fills of the reservoir with Honda PSF. It's also better when hot, noisier when cold.
But ON TOP of that whine I also have a bit of a very faint 'coffee grinder' sound, I guess from the torque converter...?

Hondas and Acuras have an o-ring seal on the PS pump inlet that may leak air causing whining, especially when colder out.
Known problem, and replacement o-rings are available, cheap and easy to install.

does the car do it at idle? if it increases with speed it could also be a wheel bearing. I had one crap out at 90K and it sounded like it was differential whine... replaced left front and noise was gone.

Never in park. Not PS Pump. New ATF. Sounds like whirring/whining possibly metal on metal. Seems to significantly quiet down in 4th or 5th. Intermediate noise that comes and goes.
