Your INFINITI QX56 features an automatic transmission that manages the gear changes for you. That means you can focus your full attention on the road ahead while you're driving, rather than having to look down at the shift knob every time you need to change gears. That comes in even handier when you're stuck in stop-and-go traffic, since you don't have to worry about constantly pressing the clutch as you switch from first gear to second and back again.

Instead, you move the gear shifter from "Park" to "Reverse" or "Drive." After that, a torque converter connects the engine and transmission and changes the gear when needed by using fluid pressure.
