Sorry for my late reply Brad, spent some time studying about electricity since my knowledge of these was decades ago and i had to refresh my memory of the ohms, amperes, volts which even during my secondary days were Greek to me.
Actually i am empowered by you and the other kindhearted enthusiast who have taken interest in my problem. All of you are encouragers and i'm learning and doing things i've not done before only because you've motivated me.
I'm taking into consideration the "Sports Mode" aspect of the car. However, there are three terminal at the top and two at the bottom and right now i'm still trying to find in the Bentley diagram their connections so i can work on the principles you've outlined. You're description of the shifter is right, it's PRND321. I'll give a feedback of how it comes out, you're right also in that we should rule out the simple matters first. After of which if the problem has not been resolved i'm going into the information outlined by rychas1.
I hope that your New Year and the coming year will be blest. This is my wishest too for the rest.
