First of all, you should only be using your RIGHT FOOT to operate the throttle AND brake. "Auto Hold" (if I understand what it is) is for people who don't know how to drive.
As I said before, if you can't start from a stop on a hill WITH AN AUTOMATIC then you shouldn't be on the road.
Learn to do it with a stick first, then go to an auto.
I've gotta stay away from this forum.
