Shifting to a higher gear in a car or truck causes

a decrease in torque and an increase in speed.


Up shifting results in torque decreases and speed increases. You can feel the power and speed differences when a vehicle goes into "overdrive." Putting a vehicle in "overdrive" lowers the torque output but increases the speed. Overdrive is useful in driving on flat surfaces, but the vehicle may not produce enough torque to power it up a steep hill.
