Whine at 75 MPH, 2003 Sienna

Take your vehicle to a Toyota dealer and have them evaluate the
problem. Sometime things are not what they should be, that's why
they have a warranty.

I have the same faint "whine" at "tip-in." But in the '03 Corolla, this whine
is noticible in the 35-40 mph range and is there in OD/3/2 gears so that makes
the source the final drive (differential). Nothing to worrry about.

My Sienna does that as well and has since new and now has 78K with no
problems.

Do you happen to have your car radio on, and on an AM station? If so it's
the electrical system, e.g. spark plugs, EFI, etc. You radio is receiving
RF bleed. Pretty normal.

Thanks for the reply but no, the radio is not on.

Hello,

Has the volume level increased since you noticed it?

Thanks for your reply

My new 2003 Corolla LE and my older '94 Corolla both have the same
transmission. Both have the low level whine but is only heard at 30
to 40 mph. The older car has 160,000 and the whine never got louder.
I'm used to it and it may just be a common thing with the toyota
tranny.
I don't remember hearing it when I let up on the gas.

I would suggest it could be a altinator whine. The '94 corolla had a
pretty loud whine when it had 38,000 miles. Ended up replacing the
altinator and that fixed the problem.

Thanks Bud!!

Perhaps it may be your wife?
