Flush and replace the PS fluid with synthetic. Redline PS Fluid cured my PS growl on my Neon.

Try ATF+4 or Redline, should go away. You may need to flush it twice.

Are you sure it isn’t it’s the clutch fan? Mine sounds like a jet engine for a few.

No clutch fan here, she still lets you you know it’s cold. There are worse things to lose sleep over.

FWIW - attached is the TSB for the cold start PS noise (different car, but still Chrysler product).
