Why does my car rev when I switch gears?

Worn out components in the transmission, such as the gears, cause slipping. Worn out transmission gears cause erratic shifting and can cause the engine to over-rev as it changes gears. The parts in the transmission wear out over time from normal driving, but there ways to reduce wear and help them last longer.

How is the throttle connected to the accelerator?

In the old days, there used to be a cable that was connected from the throttle to the accelerator. But now in the technological age, the car’s computer controls when the throttle opens and closes by the feedback it gets about the acceleration of the vehicle.
