What is the most appropriate speed to shift into 4th gear?

[DelTeagan]

Shift into 4th gear when the vehicle speed reaches above 35 mph but below 45 mph. After shifting gears (either up or down), you should gently press the accelerator pedal and slowly release the clutch pedal. Wait until the vehicle speed stabilizes before fully releasing the clutch pedal to prevent the car from jerking or causing clutch plate wear. If a downshift fails, you can add some "empty throttle" or decelerate before attempting to downshift again. When shifting gears while driving, pay attention to the following points: 1. Never look down while shifting gears: This is a very dangerous behavior. In urban areas or on highways, looking down while shifting gears may cause the vehicle to veer off course, potentially leading to accidents. 2. Pay attention to the clutch: Always press the clutch pedal all the way down. Otherwise, the engine and transmission won't fully disengage, which can cause abnormal noises and damage to the gears.
