Can You Still Drive If the Transmission Gets Flooded?

You should not continue driving if the transmission gets flooded. Water primarily enters the transmission through the vent hole, as the transmission is not completely sealed, allowing water to directly infiltrate. Additionally, during operation, if the transmission encounters cold water and the water level is high, water can be sucked in through the vent hole. Related information: 1. Immediate Oil Circulation and Replacement: Once the transmission is flooded, it must be sent to a specialized transmission repair shop within 24 hours for oil circulation and replacement. If more than 24 hours have passed but less than 48 hours, disassembly and cleaning are required. Continued use under these conditions, with the transmission gears churning in a high-temperature and high-pressure environment, will cause the mixture of water and oil to strip internal components of their protective oil film. 2. Report for Repair: After 48 hours, transmission components will oxidize and develop rust. If these rusted parts are not promptly replaced, the resulting rust can further clog the oil passages, leading to minor issues like gear shift hesitation or slipping, or severe problems such as transmission burnout. Therefore, it is recommended to report for repair immediately after flooding to avoid greater losses.

Transmission water intrusion is no trivial matter – I've seen too many people suffer from this. The transmission contains precision gears and fluid; water contamination causes fluid emulsification, compromising lubrication. If you insist on driving, increased friction between gears can cause wear or even seizure within minutes, risking total transmission failure. Worse yet, internal rust may spread, making cleanup extremely costly. A childhood friend last year kept driving through floodwater instead of stopping, only to experience complete power loss en route to repair, nearly crashing into guardrails. The 8,000+ RMB repair bill was ten times the towing cost. From a safety perspective, transmission failure may cause sudden vehicle stoppage – especially deadly on highways. Therefore, stop immediately, don't drive further, and have it professionally inspected. Prevention is key: navigate floods slowly and avoid deep water.

Should Major Car Maintenance Be Done at a 4S Shop?

Major car maintenance should be done at a 4S shop. Car maintenance items: Regularly check whether antifreeze, brake fluid, windshield washer fluid, etc., are sufficient. Regularly perform four-wheel alignment to address issues like deviation, which can easily hide potential hazards. At this time, it is necessary to promptly conduct a four-wheel alignment for the vehicle and quickly resolve the car deviation problem. Regularly inspect the wear degree of brake pads and car clutch plates, etc. Once a certain mileage is reached, the wear condition of brake pads and clutch plates should be checked. Usually, car engine oil should be checked and replaced in time, as the normal operation of the car engine and other components relies on the lubrication, cleaning, and other functions of the oil. Advantages of 4S shop maintenance: Maintenance and repairs are guaranteed; they provide car inspections corresponding to the vehicle model, as well as professional technicians and supporting tools and equipment. In terms of spare parts, 4S shops offer reliable and guaranteed parts with sufficient inventory, resulting in shorter time consumption when replacing some spare parts or performing repairs.

What does registration mileage mean?

It refers to the total distance a car has traveled, from the time it left the factory until now, including all forward and backward movements. It is one of the important criteria for judging a car's performance. Moreover, the maintenance level is also related to the car's mileage, and the extent of car maintenance required is also determined by the mileage. Below is relevant information: 1. Speedometer and odometer: The most prominent gauge on the dashboard is the speedometer, which indicates the car's speed in km/h (kilometers per hour). The car's odometer actually consists of two gauges: a speedometer and an odometer. 2. Additional information: Traditional speedometers are mechanical. A typical mechanical odometer is connected via a flexible shaft containing a steel cable. The other end of the flexible shaft is connected to a gear in the transmission. The rotation of the gear drives the steel cable, which in turn rotates a magnet inside the odometer's housing. The housing is connected to a pointer and is set to zero by a hairspring. The speed of the magnet's rotation affects the magnetic field strength, disrupting the balance and causing the pointer to move accordingly.

Can medical alcohol be used as windshield washer fluid?

Medical alcohol cannot be used as windshield washer fluid. The following are the functions of windshield washer fluid: 1. Cleaning performance: Surfactants usually have functions such as wetting, permeating, and solubilizing, thereby achieving the effect of cleaning and removing dirt. 2. Antifreeze performance: The presence of alcohol and ethylene glycol can significantly lower the freezing point of the liquid, thereby achieving an antifreeze effect and quickly dissolving frost. 3. Anti-fog performance: A single-molecule protective layer forms on the glass surface. This protective film can prevent the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear view. 4. Anti-static performance: After cleaning with windshield washer fluid, substances adsorbed on the glass surface can eliminate the charge on the glass surface, providing anti-static performance. 5. Lubrication performance: Windshield washer fluid contains ethylene glycol, which has high viscosity and can provide lubrication, reducing friction between the wiper and the glass, and preventing scratches. 6. Anti-corrosion performance: Windshield washer fluid contains various corrosion inhibitors, which have no corrosive effect on any metal, and are absolutely safe for car paint and rubber.

How long does it take to get points deducted for running a red light?

Points will be deducted as soon as running a red light is confirmed. The criteria for determining a red light violation and the handling methods are as follows: Criteria for determining a red light violation: Generally, to determine whether a vehicle has run a red light, the electronic eye needs to capture three photos. These are: the front wheels crossing the stop line, the rear wheels crossing the stop line, and the front wheels crossing the opposite stop line. Handling methods for red light violations: According to traffic laws, after a motor vehicle violation, it usually takes 3 to 7 days to check online or receive a text message notification, with a maximum delay of no more than 13 working days. If the violation is caught on the spot by traffic police and confirmed with a signature, the vehicle owner must go to the local traffic police station within 15 days of the violation to handle the matter. If it is not handled within 15 days, a 3% late fee will be charged daily. If the violation is captured by an electronic eye, the vehicle owner can check the violation record on the traffic website and go to the local traffic police station within one month before the annual vehicle inspection to handle the matter.

What are the procedures for picking up a new car?

Buying a new car involves the following procedures for pickup: 1. Vehicle Certificate of Conformity: The certificate is another important document for the car and is essential for registration. Only cars with a Certificate of Conformity meet the national requirements for motor vehicle equipment quality and related standards. 2. Purchase Invoice: The purchase invoice is the most important proof when buying a car and is also one of the documents required for registration. Therefore, be sure to request the purchase invoice from the dealer and confirm its validity. 3. Check the Nameplate: Verify the displacement, manufacturing date, chassis number, engine number, and other details on the nameplate. The numbers on the Certificate of Conformity must match the engine number and chassis number on the car. 4. Vehicle User Manual: Users must operate the vehicle according to the instructions in the user manual. Damage caused by not following the manual's instructions will not be covered by the manufacturer's warranty. The user manual also specifies the main technical parameters of the vehicle and the necessary technical data for maintenance and adjustments, serving as a reference for repairs.

What are the reasons for the noise when shifting from P to R gear?

The reasons for the noise when shifting from P to R gear are as follows. Shift solenoid valve malfunction: It is usually caused by a faulty or clogged shift solenoid valve. Shift precautions: After shifting into a new gear, release the clutch pedal smoothly and timely. The coordination between the clutch pedal, accelerator pedal, and gear lever should be correct and harmonious, with accurate positioning. The action should be swift to minimize shift time, reduce kinetic energy loss of the vehicle, and lower fuel consumption. Master the appropriate shift timing, meaning neither upshifting too early nor downshifting too late. Shifting should be determined based on the vehicle speed. You can increase the speed before upshifting and decrease the speed before downshifting. It is important to note that when downshifting, to prevent mechanical wear, it is best to use the double-clutching method for downshifting.
