5th Gen 1500 Transmission swap in a 4th Gen 1500

[Wild one]

I thought of sourcing the valvebody, clutch plates and stuff for the rebuild online to make it cheaper. Finding my transmission parts just got a little bit harder now. I was always under the impression that there was just one 8 speed being used in the 4th Gen Ram 1500, turns out there are two.
On the Mopar website, it shows these two for the 2014 model year.View attachment 536972
I put in my VIN number to try and find out, and its not showing. How do I find out which transmission is the on my truck?

As 1SL said,you have the 8HP70,only the V6's get the light duty 845
