I changed my pump because of metal flakes in the fluid. I also had a whiny on rpm changed. I successfully changed the pump, but the sound is still there, whining on rpm change range but not on wheel turning. Is there something else I should be chasing? Could it possibly be from dirty fluid still? Not sure how sensitive they are to dirty fluid (I added new fluid but did not follow flush DIY)
