You need the 8 speed and it's clock spring,they won't work on an RFE equipped truck.

Thanks to everyone that's been helping me along the way with my project. I wanted to ask. Since I have a 2013 Ram and they say the communication with that BCM make it difficult for the truck to accept changes. Should I upgrade to a 2016-2018 BCM? My truck accepts changes but some of them don’t work right and they intermittently jump back and forth between the new configuration and old on. Also if I should upgrade BCMs can I grab a used one from a local yard and reprogram it through alfaobd?

Hey everyone.
Just stopping by to add some more details and progress. I went back by the salvage yard and picked up a bcm/rf hub/keyfob I installed everything in my truck as is with no flashing or nothing. I installed the in-cab keyfob antennas and my truck will crank up remotely and from pressing the button. The issue I'm having now is that the truck starts and runs for about 5 seconds then immediately shuts off. Upon trying to restart the truck, I get the messages keyfob no detected and the vehicle is not in park and nor can I get the push to start button to cycle out of run to off once I push the button. I have to disconnect the battery cable. BCM from a 2015 Laramie with all the bells and whistles for that year. I have a 2013 Express rcsb with the old 6 speed transmission. Could it be that the truck keeps shutting down because the different VINs it detect, BCM different from the chassis? I went this direction because I was told its 200 to flash the ecu to the bcm and even then I was told theres a chance it might not work. So if anyone out there knows how to fix this issue. I'm all ears. Thanks everyone for your help.

Update.
I got the 8hp70 swapped in and I am sorting through the diagram that Russell from SGA posted here
I wired everything up following this diagram. When I try to start my truck it won’t start and my PRND lights are all illuminated yellow and the electronic shifter will illuminate P. Then intermittently my dash will show only P in the normal colors and bounce back between. When the push to start is in run without the truck running (it won’t crank) my rotary shifter shows P as well as my EVIC. I believe I either have my CAN C lines going to the wrong place. I wired them into the CAN C lines coming off the RF HUB. I think that’s the issue. Only other thing I can think of is I should wire the CAN C lines into the shifter instead of the RF HUB. But I don’t wanna start splicing electronics until I know where what goes and vice versa. Also the ignition pink/white wire, where does that wire into? Can someone whos down this guide me in the correct direction? Need my truck running before Monday morning.

Update.
I got everything working thru alfa obd (rewrote vin & installed the proper 8 speed harness connector that goes through the firewall passenger side in conjunction with the engine bay harness)!!
Thanks everyone for your help.
