There is a noise when shifting into reverse gear because manual transmissions do not have a synchronizer for the reverse gear. Therefore, when engaging reverse, the meshing of the gears can produce a sound, which is a normal phenomenon. Before shifting into reverse, it is essential to ensure that the car has come to a complete stop. If the car is not fully stopped before shifting into reverse, gear grinding may occur. Gear grinding can potentially lead to damage to the gears. Manual transmission cars are equipped with synchronizers, which the driver uses when shifting gears to select the appropriate gear. The gear lever in a manual transmission is connected to a shift fork, which in turn is connected to the synchronizer. The synchronizer makes shifting gears easier by synchronizing the rotational speeds of the gears.

What to Do When the Car Keeps Showing Unstable Tire Pressure?

Here are the solutions for when the car keeps showing unstable tire pressure: 1. Check tire pressure: The owner should promptly check the car's tire pressure. If the tire pressure is found to be too high, reduce it; if it's too low, inflate the tires in time. 2. Check for damage: Since tires bear the weight of the entire vehicle and are the only parts in direct contact with the ground, they are directly related to driving safety. The most important aspect of tires is tire pressure, so maintaining normal tire pressure is crucial. 3. Reset tire pressure: When driving, tire pressure may vary slightly in the same position and at the same temperature. Below are the reasons for unstable tire pressure: 1. Seasonal reasons: In summer, high temperatures can cause car tire pressure to expand, while in winter, low temperatures can cause it to contract. In the front of the car, where the air conditioning vents are located, when the cold air is turned on, it can become hotter than other wheels. 2. Tire reasons: Tire sealing is mainly due to its own air pressure. Over time, a small amount of air pressure may leak. It is recommended to check the tires, air pressure, etc., before starting, or keep a tire pressure gauge. If any abnormalities are found, it is advisable to go to a 4S or repair shop for inspection.

How to Handle Violations Before Taking the Driver's License Test?

If the vehicle owner's driver's license is revoked, traffic violation points cannot be processed. When handling related procedures, the driver's license must be in a normal status to proceed. If the driver's license is penalized on-site (receiving a ticket), the ticket must be brought to the designated payment office at the traffic police team where the violation occurred. For non-on-site penalties, use the driver's license to obtain a ticket at the traffic police team where the violation occurred and then proceed to the designated payment office.

What to Do If There Are Bubbles in Window Tinting Film?

Simply find something to squeeze out these bubbles. Of course, this method only works for bubbles located at the edges of the film, as those in the middle cannot be addressed this way. The same approach applies to car window tinting. You can use a bank card or a bus card to squeeze out these bubbles, and the operation is quite simple. If the bubbles at the edges of the film have been squeezed out, you can use a small needle to puncture the bubbles in the middle. This method may seem a bit aggressive.
