Weird noise

[Raines Iron Works]

Hopefully someone on here has experienced this strange chirping sound just coming off idle. It only happens when the motor is warm. It almost sounds like a loose heat shield or something. After a few minor burns while poking around I think it's coming from the back of the motor on the drivers side. It will also do it when you shut the motor off and it shakes to a stop.

Nothing major it's just annoying

Checked the Downpipe heat shield for looseness off the back of the turbo?

It's the torque converter
