What is it called when you're speeding up and the car jolts a tad and it tries to reach higher speeds? Some kind of gear shifting with automatic transmission? Should that occur at 20mph because it has been nerve racking for me and my mechanic hasn't reported anything notable concerning it so I'm assuming it is how it's supposed to be.

My mechanic test drives my car each time before returning it to me so I assume it is subtle. I wish I could find a car guy to drive shotgun with me. By the way your advertisement bar at the bottom covers my text when I'm typing so I can't see what I'm writting until I exit the keyboard.
