How many kilometers should the transmission fluid of a general automatic transmission car be replaced?

There is no unified standard for the replacement of transmission fluid. Generally, automatic transmission fluid should be replaced every 2 years or 40,000 kilometers, while manual transmission fluid is usually replaced every 40,000-60,000 kilometers. Transmission fluid is an oil product that keeps the gear system clean, ensuring the normal operation of the transmission and extending the life of the transmission device. The methods for replacing transmission fluid are as follows: 1. Gravity replacement. The principle is the same as changing engine oil. Loosen the bolt of the oil pan and let the transmission fluid flow out by gravity. This method is the simplest, but it cannot completely drain the transmission fluid, mainly because there are dead corners such as depressions and pits in the mechanical structure. 2. Circulation machine replacement. New transmission fluid is added to the circulation machine, which is connected to the oil circuit interface of the transmission. Under hydraulic pressure, the new fluid pushes out the old fluid. This method cleans the oil circuit more thoroughly. The more new transmission fluid used, the cleaner the cleaning. A single circulation machine replacement requires about 10-13 liters of transmission fluid. The replacement time is approximately 40-80 minutes. 3. Oil pan removal replacement. This method is a root cleaning method and can also clean the oil filter. Since the disassembly process requires excessive manpower, 4S shops generally do not do this.

How to Adjust Wheel Camber Angle?

Four-wheel alignment camber angle requires professional instrument calibration. It is recommended to adjust at a 4S shop. The camber angle varies for different vehicles. Below is an example using the Porsche Cayenne, with the camber angle adjustment method as follows: 1. Use a four-wheel alignment machine to check all data and adjust according to the vehicle's standards. 2. Use the target wheel of the alignment machine to detect wheel data. 3. Adjust the toe adjustment nut. If the data shows red, it needs adjustment. Adjust directly to the standard green display data. 4. Adjust the front wheel camber angle bolt. If the data shows red, it needs adjustment. Adjust directly to the standard green display data. 5. Adjust the left rear camber angle bolt. If the data shows red, it needs adjustment. Adjust directly to the standard green display data. 6. Adjust the right rear wheel camber angle bolt. If the data shows red, it needs adjustment. Adjust directly to the standard green display value. Effects of incorrect wheel camber angle on the vehicle: 1. Excessive positive camber angle can cause unilateral wear on the outer side of the tire; accelerated wear of suspension system components; the vehicle will drift towards the side with a larger positive camber angle. 2. Excessive negative camber angle can cause unilateral wear on the inner side of the tire; accelerated wear of suspension system components; the vehicle will drift towards the side with a smaller negative camber angle.

Why is the reverse light not working?

When reversing, the reverse light sends a reversing signal to people behind the vehicle. The main reasons for the reverse light not working are as follows: 1. The reverse light bulb is damaged and not functioning. 2. Faulty reverse gear switch in manual transmissions or faulty gear position switch in automatic transmissions. 3. The fuse in the reverse light circuit is blown. 4. Open circuit or poor contact in the reverse gear switch signal line. Self-inspection methods are as follows: 1. Test by honking the horn or turning on the signal light switch. If the horn sounds and the turn signal lights up, it indicates that the power line before the fuse is in good condition. Therefore, you can use a test light or the power short-circuit method to check for open circuits at the ammeter terminal, ignition switch terminal, light switch terminal, etc., in sequence. If the circuit connection is good, the light switch may be damaged. 2. If the horn does not sound when tested and the fuse has not tripped, it indicates an open circuit or poor connection somewhere in the power line before the fuse. If the fuse trips, it indicates a ground fault somewhere in the line after the fuse. You can disconnect the power lines of the horn and turn signal, then press the fuse button to test. If the fuse does not trip again and the lights turn on when the light switch is activated, it indicates a ground fault in the horn or turn signal circuit. If the fuse still trips, use the power short-circuit method to locate the ground fault in sequence. 3. If the test light shows good power at the light switch terminal, but when a certain position of the light switch is activated, the bimetal contacts frequently open and the light does not turn on, it indicates a ground fault somewhere in that light circuit. 4. While driving at night, if all the lights suddenly go out, stop the vehicle immediately and test the horn. If the horn sounds, it indicates that the power supply is still good, and you should still check the light circuit for ground faults or open circuits in sequence. If the horn does not sound, it may be due to the power line coming loose or breaking during driving. First, check the battery terminals for good connection, then proceed with the sequential inspection.

What Causes the Sound When Wiper Blades Scrape the Windshield?

The reasons for the sound produced when wiper blades scrape the windshield are as follows: 1. Issues with the wiper blade itself. Wiper blades are made of rubber and can harden or age over time, especially in winter. If they no longer clean effectively, the simplest and most effective solution is to replace them. Generally, wiper blades should be replaced every one to two years. 2. Foreign objects between the wiper blade and windshield. When the wipers are activated, sharp friction noises may occur if there are debris or dirt trapped between the blade and windshield. Inspect and clean the wiper blade or the area beneath it to ensure it remains clean. 3. Deformation of the linkage mechanism or issues with the motor or interval relay. (For example, if the wipers move too fast, too slow, or continuously, it may cause unusual noises.) Long-term use can also lead to deformation, stiffness, rust, or abnormal movement of the mechanism. If you've recently replaced the wiper blades, check for dirt or oil residue on the windshield. Clean the glass with a cleaning solution or try another new set of blades. If the noise persists, use pliers to adjust the angle of the wiper arm. 4. Incorrect angle between the windshield and wiper arm. In most cases, the sound occurs due to misalignment of the wiper arm, causing the blade to bounce on the windshield. If the blade is in good condition, adjust the angle of the wiper arm so that the blade is perpendicular to the windshield. You can use pliers to adjust it yourself: place a cloth under the head of the wiper arm, grip it with pliers, and gently bend it to ensure the blade is perpendicular to the windshield.
