I have what sounds like a whining noise that is often produced from low power steering fluid or an alternator that is going bad. Both of those the dealer replaced, and now they also have replaced under their cost (bought Jeep 1 month ago), all the idler pulleys and belt tensioner. It's still there. I've had four jeeps over the last 30 years and this one is stumping me and the mechanics.

I felt all along it was coming from the transmission. The whining goes up and down with revs and is present in gear or out of gear. Any ideas out there? Thanks in advance.
