Automatic transmission out

My brother car transmission went out. I’ve never changed an automatic transmission before but I have changed a manual transmission.My question is when your changing an automatic transmission do you have to reprogram anything like the transmission computer or is it plug and play.btw it’s a 2005 Acura tl

Google Acura TL transmission replacement and watch a dozen videos to see if you can handle it.
