Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
I understand that but I’m j having problems atm with mine. I had recently bought a new trans that came out of another ve with the same axel and trans number but when I lined up the new one and the old one I was replacing they didn’t match up and the new trans was a 16 pin where as the old one was a 20 pin I’m not sure if it makes sense to you but I’m just wondering if they are interchangeableif you mean a 5l40e
it can be swapped with another 5l40e
if you want to fit a manual or a 6l90e a lot of work
