White.6.2

have a 2013 sierra Denali. The motor let go and the trans was getting there as well. I just bought another l9h with a 6l80 already together but out a 2010 sierra Denali. Am I plug and play and drop in and bolt up no ecu change or tuning? Does the tranny have different programming is it just gonna go into limp mode? I hope the motor will directly bolt in at least I’m hoping anyway. Please help I’m no gm technician
