I have a 2000 Chevrolet Impala a 3.6 V6 automatic transmission. For the pa s month or so I have been noticing a high pitch moaning whine noise coming from under the hood. It seems to be more prevalent when I am making a turn (makes no difference if it is a right or left turn) it can be heard by others since I notice people will look at where this noise is coming from & 9 times out of 10 it is me. At first I thought it might have something to do with the power steering. I began tho king there have been a couple of times when I have not been to kind to the gears &/or transmission. We recently had the engine flushed along with an oil change. The radiator/coolant system had a gunk in the line & our coolant system dashboard light was on most of the time (if it did go out if would come back) I first changed the radiator cap then took it in for the flush & has been like a charm except for this whine when I turn. It might continue to whine once the turn has been completed but will stop. The steering seems a little tighter when driving the car. This is why I thought steering would be the problem instead of the much dreaded transmission failure. I am at a loss of what the problem could be since the auto shop I take the car to I just feel the service as well as the information I am getting from them leads me to feeling that I might be someone who is due to my lack of knowledge could be taken advantage of. It was suggested to have a second opinion only being on fixed income that isn't always a feasible remedy for me. Please any idea of what this could be? I did see the blog about whining coming from the engine when it was being driven with no comments as to it being a problem during turns. So I assumed this was occurring when the car was just being driven. I do not have a diagnostic tool to see what calibrator code comes from the diagnosis. As I mentioned previously I'm on a fixed income. I also had the serpentine (?) belt replaced the same time as the flush. Any possible ideas on this high pitched moaning whine & what I can do about it. Your suggestions would be great!y appreciated. Being new to this as well as a woman ( but don't hold that against me) I might have put this post in the wrong place. Oops !!
