What to Do When Vehicle Transmission Fails?

Here are the repair methods for automatic transmission failures: 1. Automatic transmission oil leakage. Repair method: If the sealing ring is aged, simply replace it. If the joint surface of the transmission case is damaged, thicken the paper gasket appropriately for repair. However, for severe leakage, welding repair is required. 2. Improper throttle cable or throttle position sensor. Repair method: The position needs to be readjusted. 3. Faulty speed sensor. Repair method: A new sensor needs to be replaced. 4. Engine idling. The transmission suddenly shifts from high gear to low gear, which is likely due to abnormalities in the control system or cooling system. Repair method: It needs to be handled by professionals.

How to Repair Scratches on Plastic Bumpers?

Here are the methods to repair scratches on plastic bumpers: 1. Toothpaste: When the bottom of the front bumper is scratched, using toothpaste is very effective because toothpaste itself has a polishing function, which is equivalent to applying a layer of wax to your car, thus achieving a good repair effect. However, toothpaste can only be used for minor scratches; it has little effect on deeper ones. 2. Paint Scratch Repair Agent: As the name suggests, the paint scratch repair agent is also used to repair bumper damage. In fact, it works on the same principle as toothpaste, with a polishing effect that can quickly repair the damaged part of the paint. Of course, this can only repair minor scratches. 3. Touch-up Paint Pen: Using a touch-up paint pen can cover up some small and shallow scratches, making them less noticeable. Although there is still a certain gap compared to the original factory paint (color difference exists), and the durability is certainly not comparable to the original factory paint, after all, the touch-up paint pen is only for local touch-ups, the overall effect is relatively good.

What to Do If Gasoline is Added to a Diesel Car?

If you realize that the wrong fuel has been added, the first thing to do is to assess the amount of fuel added. If only a small amount of gasoline has been added recently, you may not need to take any action. However, if a significant amount has been added, you should immediately go to a 4S shop to drain the gasoline and clean the engine and fuel system. Here are the consequences and solutions: 1. Since the ignition point of diesel is much higher than that of gasoline, the diesel car can still be started after adding gasoline, as the diesel engine can easily compress and ignite the gasoline. However, over time, abnormal idling and white smoke from the exhaust pipe may occur. 2. If you have been driving for a while before discovering the issue, regardless of whether the car can still be driven, you should stop immediately, call a tow truck to move the car to a 4S shop or repair shop, quickly drain all the gasoline from the fuel tank, and then perform necessary cleaning of the fuel tank, engine, and fuel system, as well as replace any damaged parts.

What to Do When It Rains Heavily After Car Tinting?

Rain after car tinting has no effect because the film is applied to the inside of the car. As long as you don't open the windows, the rain won't reach the film. Additionally, after the film is applied, you should not open the windows for 48 hours. Below are some precautions to take after tinting: 1. Do not open the side windows for 48 hours after tinting; 2. Do not use solutions containing alcohol or ammonia to clean the tinted film; 3. If there are bubbles, they must be addressed at the tinting shop within 24 hours—do not attempt to fix them yourself; 4. Avoid placing adhesive labels directly on the tinted film; 5. You can clean the film after 2-3 weeks using a lint-free towel or other soft materials—do not use stiff brushes or hard objects to avoid scratching the film; 6. After tinting, there may be fogging between the glass, which is normal and will disappear within 2-3 weeks.

The extended introduction of Zhejiang license plate numbers is as follows: Zhejiang license plate numbers are arranged clockwise from the provincial capital in alphabetical order. Previously, the starting numbers following each letter were also sorted clockwise from the regional capital. Due to insufficient number resources in some counties and cities and idle resources in others, and now with the introduction of personalized license plates, there is no numerical sorting.

How to Check if a Car Has Been in an Accident

To determine whether a car has been in an accident, you can start by observing whether the gaps between the body panels are uniform and consistent, and whether the side body lines are smooth. If you notice that the waistline is noticeably uneven, you can conclude that the car has been involved in a collision, and a relatively severe one at that. Here are specific steps to check if a car has been in an accident: 1. Inspect the A, B, and C pillars and seals: Open the car door and pull down the original factory door seal. The door frame and pillars should be straight. Pay special attention to the original factory weld points where the A, B, and C pillars meet the car body—they should be slightly rounded and slightly recessed. The lines extending from the roof to the sill should be straight and naturally curved. If you find it difficult to close the door or notice gaps when opening it, this indicates that the door has been removed before, and the car is definitely an accident vehicle. Such a car should not be purchased. 2. Check the side fenders: When inspecting the engine, it’s not enough to just see if the layout is neat. Focus on whether the screws on both side fenders have been replaced, whether the original weld points are intact, and whether the surface of the anti-collision beam is smooth. If the anti-collision beam is deformed or the surface is uneven, the car is likely a rear-end collision vehicle. 3. Examine the glass: The front and rear windshields and the four door glasses should normally be consistent. If the dates on them don’t match, the car may have had its glass replaced due to a major accident. 4. Look at the bumper: Areas like the bumper, which are prone to scratches, are most likely to have been repainted. However, because this part has a relatively large recoverable deformation, minor scratches may not show wrinkles after repair. Moreover, if the scratches are shallow and don’t expose the primer, polishing can restore them to their original condition.
