check all the connectors and clean them. Did you replace the cable that goes from the TCM to the transmission and where does the cable for the selector switch go?
Symptoms say cable problem but that can also mean solder joints inside TCM you can open that up, I think on TCM need to drill out a could rivets. I opened up mine when I thought TCM was the problem before I figured out it was the connector.
Maybe your connector is not seating completely etc you need to determine if the connection is the problem
