Car Forum / Toyota / Toyota Cars / October 20062002 Avalon drivetrain starting to whine at 28 to 30 miles per hour...
It's a low whine, and only present at 28 to 30 mph, but it's there. Will it get worse? Is there anything I can do to prevent it getting worse? Steve Henderson > It's a low whine, and only present at 28 to 30 mph, but it's there. Will > it get worse? Is there anything I can do to prevent it getting worse? > > Steve Henderson Gear whine is generally not something that develops over time unless there is fluid loss or incorrect fluid added to the transmission and/or differential. I would check the condition and fluid level of the automatic transmission fluid (ATF), and if it was recently serviced, check the type of ATF that was added. Are you sure that the whine is not engine RPM-related? In other words, note the engine RPM that the whine occurs at and see if it happens when you rev the engine to that RPM with the car in park or neutral. If so, check the power steering fluid level to make sure it is not low. Low power steering fluid will make the PS pump whine. This is the most likely cause of the whine. If the PS fluid is low, check for leaks in the PS system. Other things that can cause a whine are tires (tread pattern, improper inflation, or road surface); alternator; wheel bearings; water pump; idler pulleys; and AC compressor.

What would we on the ng do without you? Many thanks (even from one whose Avalon is Not whining!) >>> It's a low whine, and only present at 28 to 30 mph, but it's there. Will >>> it get worse?

Many thanks (even > from one whose Avalon is Not whining!) Thanks for the vote of confidence! Hopefully, the OP will let us know what the cause is. Now, if I could only get my 16 year old daughter to stop whining when one of her brothers has the Avalon that they share!

Make sure she has the correct fluid installed. >>>> It's a low whine, and only present at 28 to 30 mph, but it's there. Will it get worse? Is there anything I can do to prevent it >>>> getting worse?

She will be so upset everybody will forget about the car! Just kidding Ray, I would wish the battle that would start on any other teenagers father.
