Can someone tell me why can't a 2012 Acadia SLT 3.6 AWD engine cannot work for a 2011 or 2013 and up to 2017? What is the difference? Appreciate you all for the help

I would expect a 2012 engine to interchange with an '11 or '13. They all used the LLT engine.

2017's have the LGX engine. I would not a previous year's engine to be plug and play.
