I have a 2012 Tahoe with approximately 100k that I bought about 6 months ago. Unfortunately I recently had to have the transmission rebuilt (AAMCO). After the rebuild, I'm now experiencing a low squeak / slight rubbing noise at rolling acceleration (see youtube link below). I took it back to AAMCO. They examined transmission, u-joint, etc. and finally stated that it was a broken motor mount, which I had replaced. However, the noise is still there. I want to make sure it is safe to operate and see if this is related to the new transmission install. I will take it back to AAMCO, but I would like some other opinions first. Has anyone experienced this? Anyone know what it could be? Thank you!
