Shula has been the team's quarterbacks coach since they drafted Newton in 2011, but moves up to the offensive coordinator role for the 2013 NFL season following Rob Chudzinski's move to the Cleveland Browns.
The quarterback told NFL Radio: "If I don't like this play or feel comfortable, [Shula is] not going to call it. That's probably the most positive thing with us right now, me and coach Shula me being on the same page going into the season.
"The time is now. I think everybody knows that in this organisation, from the janitor down to the head coach."
The Panthers face the Chicago Bears in their first pre-season game tomorrow evening.
