hey guys, maybe you can shed some light on this problem for me. i started hearing a strange wistling noise about 2 weeks ago. thought it was front of the engine. it has 113, 250 miles. changed the serpentine, & idler pulley. still does it. won't do it when i start it in the morning, when it warms up, the noise starts. doesn't sound like a vacuum leak. don't hear it when idling or at highway speeds. hear it when taking off from about 1600 - 1800 rpm. i put it up on a rack with a friend inside to start it . when under it with it running it sounded like it was coming from the bell housing. (i think) sounds are hard to pinpoint sometimes. does the torque converter make sounds like this? i know squat about transmissions. can change the filter though. drivability hasn't been affected though, shifts ok. anyway, hope you all can help. thanks in advance.
