My truck does the same thing.

Check the Power steering fluid and add if needed. If it runs low for a while it will have a tendency to wine even with fluid in it.

Sounds like you have checked everything else I can think of.

Hope you figure it out.

How loud is the whining? Where's it coming from? Could be the PS pump I guess. Kinda sounds like your tranny might be noisy in gear. Meaning it may be something internally with the transmission that your hearing. Unless it's coming from another part of the vehicle, possibly another part of the drivetrain.

The timing belt should be replaced every 60K. It wouldn't be whining I don't think though.
