Good afternoon,
The transmission was an option for the 3.5 motor. So the simple answer is yes.
In order to perform this you will need to get a wire harness and most likely the PCM which has the TCM inside it. You will need the correct PCM and have it programmed to the car.

So the PCM has to be from a 3.5 or 5.7? And the wiring harness is the engine wiring harness?

The harness has to be from a 3.5 with the trans you are using.
