Whining noise coming from transmission?

Adamd · December 11, 2022

Just bought a 2022 with the 2.7 turbo. I hear a whining noise on slow acceleration that’s constant, and sounds like it’s coming from the transmission. I hear it during deceleration too, it always seems to match the transmission. I had a 2020 with the 2.7 turbo and never had this sound, curious if others have noticed anything similar. It almost sounds like the turbo spooling, but I don’t think it’s the turbo because if can hear that along with this noise. Thanks in advance.
