I personally pinpointed the noise at the transmission cooler line ports on the trans case using a stethoscope and prod. The used dealer that I bought it from offered to pay for replacement if it fails, however refused to look further into the problem due to cost. I guess that is my failure to hold my ground. He flushed the trans fluid, changed the filter, replaced the cooler lines (after he stripped the fitting on one) but the noise still exists. This iis definitely NOT a power steering pump noise, alternator bearing, or anything else as it originates from the top of the transmission case.

My wife has a 2009 SXT AWD that developed an intermittent "whine" soon after we left the used dealership where we bought it. The noise does not change pitch and sounds similar to a reed vibrating at a high frequency. Using a stethoscope I located the noise originating from the top of the transmission where the cooler lines exit. The noise occurs frequently while driving (at least at lower speeds) and also while at a stop, either parked or in gear, but not all the time. The noise does not seem to affect the car's drivability that I can tell, however the noise is incredibly annoying and concerning. I cannot afford to trade it (I tried) so I'm hoping that someone out there might help me narrow in on this problem. The dealer where I took it several months ago speculated a diagnosis of the front transmission pump, however they would not confirm the diagnosis without performing a complete teardown...um ...no. This is my wife's daily driver so I'd like to take care of this soon if I can. Thanks in advance!
