Transmission codes 4.2L (6 codes in all)

Thank you MAY03LT for introducing me to this helpful resource, I am the proud new owner of an 06 envoy sle 4200 4x4

I have the following codes;

p0411
p0976
p0787
p0973
p2769
p2764

Feels like no power, been told it’s the cat plugged, checked the codes, transmission codes and that is must be in safe mode, been told just replace the transmission. Discovered mice droppings, I’m thinking bad ground or a mouse chewed through a wire.

Sounds like mice chewed several wires! I would suggest closely inspecting the harness to the transmission
