I've just completed one

Mine was SRT (from several donors) into my NA Roadster

Automatic to automatic

My understanding is that you cannot install the manual trams into this setup

The drive shaft is different, the rear components are different as well. You have to flash the ECU to make it compatible. TCU would have to be from an SRT.

Suspension and brakes remain the same
Power steering hoses are different, same steering box, different trans lines at the rad to accommodate the SC cooler

You will also have to run power to the SC Waterpumpnand the secondary air pump

It's doable, it's a question of time and money. The money adds up in a hurry
