2007 Hybred Camry has developed a whine

It seems to be a well known issue

..

that issue sounds like a vacuum leak. or a possible small break on the air cabin

Where is the whining noise actually coming from .. engine/gearbox or elsewhere?
A whining/screeching noise could be a drive belt .. such as the belt that drives the alternator.

On a manual car it could be the clutch bearing making the noise until it warms up. Does the clutch make a noise when you depress the pedal? That's the thrust bearing .. the bearing that operates the clutch.

I don't think you have too much to worry about. If you had engine trouble there would be knocks, rumbles and strange noises at all speeds.

A whining noise is usually associated with something spinning/turning .. such as a pulley/idler on a drive belt or a bearing alternator.

Put your mind at rest - get a mobile mechanic's opinion.

I never suggest flushing a trans

Just remove the pan & clean

If you want most of the fluid out,
drive it a week or so then drain again.

I suspect the noise is the trans pump,
but don't know exactly how any dirt sediment
flushed into it would cause a noise

it could be anything but it sounds like it got very hot and sezied up on her,,,if this is right, its likley to need a new engine soon?

you could be low on transmission fluid check that and make sure it registering properly on the dipstick.

I had the same problem. You can get a new wheel bearing for about $50 (if I remember right) from Advance or some similar auto parts store. Mine was seized up and had to be cut off.

Possible low on fluid will make uniquik whine noise,But another common whine noise is fron serp belt idler pulley,noise will increase with speed.

Just a thought- remove the oil filler cap when the whine is present - (this checks if PCV valve is faulty, causing high crankcase vacuum, which in turn causes a whistling/whine noise as air leaks past engine oil seals). Worth a check.

Try listening with a short piece of hose pipe to locate immediate area/source of noise.
