What causes the car to not shift gears when running but can shift when turned off?

[ReaganMarie]

The issue where the car cannot shift gears when running but can shift when turned off is likely caused by a clutch or transmission malfunction and should be promptly checked at a repair shop. Here is more information about car gear shifting: 1. Basic Gear Shifting: While driving, learn to select the appropriate gear based on road conditions and master the timing of gear shifts. Start in a low gear and quickly switch to higher gears as road conditions permit. 2. Gear Shifting for Beginners: New drivers should not rush to drive on the road. Instead, they can practice stationary gear shifting first. Familiarize themselves with the gear lever diagram and mentally simulate the shifting steps. Once slightly familiar, practice the shifting methods used during normal driving while stationary. If still preparing for a driver's license, even more practice is needed, starting with how to hold the gear lever. Gear shifting should not be stiff; gently hold the gear knob with the palm and naturally curl the fingers. The shifting action should be smooth and slow.
