- Does it happen when standing if you raise the RPMs up to 2-3,000? If yes, listen closely to the alternator.
- Is it related to road speed? If so, then you should put it on a chassis lift, wheels free, then cause it to happen by putting it in gear and raising RPMs to road speed.
I suspect it isn't the acceleration that causes the pitch to change but rather engine RPMs.
You could check this while on the road by starting in a lower gear and noting when the whine is very noticeable, then slip into the next higher gear to see if the whine changes or remains the same. If it remains, it probably isn't related to the engine but to some rotating part(s) outside it (for example, wheel bearings.) If it changes, then the noise is coming from some engine component and alternators can do this when the amperage load is high; it's also a part that turns at a fairly high speed and will 'whine' rather than 'growl.'

Have the tranny serviced with fluid change and filter, if noise it still there it is the torque converter . Have the dealer fix it ,and have it on paper with dealer invoice when it is done. Do all this before warranty expires. IT IS NOT USUAL for any car, Toyota included, to have tranny whine!!!!!
