Скачать или смотреть 2016 Chevy Tahoe annoying chirping noise

There has always been this very annoying chirping noise coming from underneath my Tahoe. You can hear it at idle, especially when next to restaurant drive through windows. The dealer first told me they couldnt duplicate the noise then after a lengthy battle, they finally told me they located the problem and that it was the trasnmission's flexplate. They replaced that under warrantee and the mechanic wrote that the noise was gone. Well, no it wasnt. I didn't have time to argue anymore and wanted to try to find the noise myself. Using a mechanic's stethiscope, I found the noise coming from within the bellhpusong of the transmission. This houses the flexplate and the torque converter.
The flexplate really just a solid piece of metal where the torque converter is made up of several components. I believe it is coming from the torque converter. Can anyone else confirm this?
