Guys, I’ve got 2015 with about 140k on it.

I deleted it right after my 100k warranty with a DRD tuner.

My transmission randomly started squealing.

It doesn’t often happen when downshifting from high gear into a lower gear at moderate speeds.

If my work serves me correctly, it’s typically from 5th to 4th or 4th to 3rd.

It will squeal/wine just for a second when it hits those hover rpm’s during the downshift.

Does anybody have any idea about s what it could be?
