For anyone interested in making this swap, here are the key details:
1) The manual mode (pushing shifter to the left and shifting up/down) does not work. I get a "shifter error" in the display when I try.
2) You need the shifter, the upper plate where the shifter mounts in the console, and the lower bracket for the console. It needs to include the wiring. You can see the parts I bought below, though the console wiring was included and not shown below.
3) If you have an AWD Durango with the transfer case, you either need the console wiring from a similar 2018 or, if you use a console without the AWD switch, you'll need to patch wires and swap i n your transfer case switch in place of the cubby hole. My donor console was from an SRT and my Durango was an R/T with the transfer case switch so I had to splice the connector for the new shifter onto my old console wiring harness. The wire colors are the same.
4) You have to remove the complete console, armrest and all, from the vehicle. It's a bit of surgery to get it all out. Lot's of parts make up the console.
5) I paid a little over $350 for the parts.
