I am looking to put an Allison transmission (hopefully get tapshift installed too ) in my 05 2500 I was wondering if anyone has done this and if so how hard is it

Why would you put a weaker transmission in?

It has been done, google it and you will find kits, the Allison is a much bigger trans! Clearances are issues with them.
It will need a standalone controller, bell housing adapter, etc. it's a costly swap
