Transmission noise when cold on a 2015 3.8 sedan

[BenGenesis]

Hello. The tranny was replaced under warranty 12k miles ago with a factory unit. When the car is cold, it makes a Straining noise when it’s put into reverse. Does anyone else have this problem? The noise goes away after it’s warmed up a bit. I have no doubt the dealer will say “it’s normal“ or “can’t duplicate”. Thanks all.

Probably it's a transmission mount issue.

Or probably the Shift Solenoid that is responsible for P to R is problematic.


It's a guess.
