Dry joints in the shifter will throw a code, probably P1856.
This code is a pretty sure sign that the optical sensors in the shifter need to be resoldered. If you can get the shifter out then any electronics technician should be able to resolder it. You need a temperature controlled soldering station with a long thin tip.
