2014 Police Interceptor Transmission knocking

[egregiousturtle]

Hey Guys, I have a 2014 Interceptor 3.7L that has a hard KNOCK when I shift from park to drive. Otherwise, no issues to note - I've gone as far as replacing the wire harness, pretty much all the way up to replacing the transmission itself. Maybe I missed something - Any ideas?

Welcome to the Forum.
I can't see the wiring causing that issue. Possibly the transmission or PTU?

Thanks! I’ll look into the PTU - I’m just hoping it’s not the transmission but if push comes to shove I’ll have to just replace it
