Hello thanks for using 2CarPros.com. It seems you have connections that are loose after a transmission replacement like that. Here are some wiring diagrams to give you and idea of what is going on. There is the transmission switch itself which looks like it sends the ECM the Park/Neut signal. Hopefully this helps, but I am sure you have a loose connector somewhere.
