well idk if this is normal.. but i have a slight slope to my driveway and today i was backing it up it and my car as soon as i let of the gas the car started to roll foward in reverse is that normal for automatice

 

it used to happen back when i had my civic just the other way around, i'd be on an uphill and 'sometimes' (very few) it would roll back on me if i let go of the brake. btw it was automatic, dont kno why it would happen on a G
