Re: IML: Transmission "whine"

[Christopher H <imperial67@xxxxxxxxxxxxx>]

Joe,

Item #1 is "the Highland Park Hummingbird," the characteristic sound of Chrysler's legendary gear-reduction high-speed starter. It is to be cherished!

Item #2 is not something I've encountered in any of my Mopars, from 1963 to the present. The only characteristic high-pitched sound while driving that I know of is a subtle "chord change" as a Torqueflite downshifts from 2nd into 1st as you approach a stop. There should be no significantly audible whine while driving, so I suspect you car might be singing about an impending problem or excessive wear to a bearing or gearset (such as the differential). If it's related to driving speed but not engine speed (without chaning accelerator-pedal pressure, downshift the car into 2nd at 35 mph and see if it changes pitch), you can pretty much rule out the transmission and focus on the rear end, wheel bearings, driveshaft/carrier, or even the tires.

>Indicative of most all Chryslers I have encountered, two unique conditions exist - 1) the distinct sound of the starter and or engine while turning over just before ignition, and 2) a constant "whine" while motoring down the highway which increases and changes intonation as the vehicle's speed changes.  My question is this - the rotational "whine", perhaps from the tranny or drive shaft - Is that something that can be indicative of a componet about to fail?  I had the tranny rebuilt upon purchasing vehicle, sodoubt if the noise is transmission failure about to happen.  Any thoughts please.  Joe A.
