Rough transmision on 2011 Toyota Corolla

I have rough transmision when I change my gear from park to reverse on downhill or uphill. I don't know what's the problem? I'd like to tell the TOYOTA mechanic when I do routine 5000 check up n oil change. Just don't know why it happens? Is it normal or something wrong with my corolla 2011? thank you so much ...
