Final answer:
The gear shift lever or gear selector lever moves when a customer shifts their car from reverse to park to neutral.
Step-by-step explanation:
When a customer shifts their car from reverse to park to neutral, the part that moves is the gear shift lever or gear selector lever. This lever is connected to the transmission system of the car, which is responsible for controlling the transfer of power from the engine to the wheels.
When the car is in reverse, the gear shift lever moves to engage the reverse gear, which makes the car move backwards. When the car is shifted from reverse to park, the gear shift lever moves to engage the park gear, which locks the wheels in place and prevents the car from moving. When the car is shifted from park to neutral, the gear shift lever moves to disengage all gears, allowing the wheels to rotate freely without any power from the engine.
So, in summary, the gear shift lever or gear selector lever moves when a customer shifts their car from reverse to park to neutral.
