There are usually no problems after repairing a water-ingressed transmission. A properly repaired transmission will not have sequelae; those with sequelae are due to incomplete repairs. The transmission is a very important component of a vehicle, capable of changing the gear ratio and expanding the torque and speed of the driving wheels. Relevant information about the transmission is as follows: Introduction: A device that changes the speed ratio and direction of motion. It is used to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. A gear-driven transmission generally consists of a casing and several gear pairs. Function: During vehicle operation, to adapt to different working conditions, the driving force and speed of the vehicle need to vary within a certain range. However, the existing engine's torque and speed variation range cannot meet this requirement, hence the installation of a transmission.

I've been in this industry at the repair shop for over twenty years and have seen many cases of transmission water ingress. Whether there are still issues after repair depends on the extent of water damage and the quality of the repair. If the water ingress is minor and timely flushing and oil change are performed, it might be fine after repair. However, if the submersion is deep, internal components like gears or circuit boards may rust and get damaged, leaving potential hidden issues even after repair, such as gear shifting hesitation or abnormal noises. During the repair, it's essential to thoroughly replace the seals and oil filter, and test the electrical system. After repair, a test drive of 30 to 50 kilometers is necessary to check for temperature rise or increased noise. Follow-up maintenance is crucial: change the transmission oil every 20,000 to 30,000 kilometers to avoid long-term corrosion risks. Remember, a transmission that has suffered water damage is prone to premature aging, and if the repair cost is high, replacing it with a new one might be more cost-effective.

Is Audi a Domestic Car?

FAW-Audi is currently a domestic car, but a small portion of its components still need to be imported. Here are the specific details: 1. FAW-Audi is a domestic brand. Audi is a brand under FAW-Volkswagen, but its parent company is the Volkswagen Group; 2. There are both domestic and imported models. The entire A6 and A4 series (including RS series, S series, diesel engine series, wagon series, and A6 allroad) have been localized; 3. Among the three German automotive giants, Audi was the first to implement domestic production in China, manufactured by FAW. The first domestic Audi was the Audi 100 (now discontinued), which can no longer enter the inner ring roads and highways (due to emissions standards below Euro 3).

Can a car still run with a broken battery cell?

A battery with a broken cell cannot be used and should be repaired immediately. The phenomenon of a broken battery cell refers to the disconnection of the internal electrode plate bridge, causing the car battery to fail to function properly (insufficient voltage). There are three main reasons for a broken battery cell: 1. Poor quality of the battery itself. 2. Incorrect usage of the battery: Long-term deep discharge and the use of high-power car chargers can both lead to a broken battery cell. 3. The battery has suffered severe impact or falling, causing internal electrode plates to break. Regarding battery usage, the following precautions should be noted: 1. Prevent over-discharge: When a battery is discharged beyond its termination voltage, continued discharge is called over-discharge. Over-discharge can severely damage the battery, adversely affecting its electrical performance and cycle life. 2. Prevent overcharging: Overcharging increases water loss in the battery, accelerates grid corrosion, softens the active material, and raises the likelihood of battery deformation. 3. Prevent short circuits: In a short-circuit state, the battery's short-circuit current can reach hundreds of amperes. The stronger the short-circuit contact, the greater the short-circuit current, generating significant heat at all connection points, especially at weak spots, which can melt the connections and cause a short circuit.

What to Do When All 12 Points on Your Driver's License Are Deducted?

If a driver accumulates 12 penalty points during the probationary period, the driver's license will be revoked, and the driver must re-study and retake the driving test. If 12 points are deducted after the probationary period, the driver must undergo 7 days of study and training and retake the theoretical test (Subject One). Below are the detailed regulations: If a motor vehicle driver accumulates 12 penalty points within a single scoring cycle, they must report to the traffic management department of the public security authority at the place where the driver's license was issued or where the violation occurred within 15 days to receive 7 days of education on road traffic safety laws, regulations, and related knowledge. After completing the education, the vehicle management office must administer the Subject One test within 20 days.

How to Deal with Gear Shifting Jerk in Skoda Octavia Transmission?

To eliminate gear shifting jerk in Skoda Octavia, first check if the transmission temperature is normal. If not, inspect the transmission cooling system. Replace the transmission fluid, which should be changed every 2 years or 40,000 kilometers. Also, check if the internal valve body of the transmission is damaged. Below is a detailed analysis of the jerk issue: 1. The function of the transmission is to change the speed ratio between the engine and the wheels. Simply put, it selects gears of different sizes to combine with the engine to adapt to different driving conditions. Gear shifting jerk occurs when the transmission breaks the original inertia during the process of switching between two different gears, and the sudden force generated reacts on the car body, causing the jerk phenomenon. Generally, the lower the gear, the higher the engine torque amplification ratio, and the more obvious the jerk. Therefore, the jerk sensation usually occurs during the process of shifting from 1st to 2nd gear or from 2nd to 3rd gear. 2. Sudden acceleration or braking followed by acceleration are the two situations most likely to cause jerk. The computer's shifting logic is based on the driver's throttle input. Normally, when the driver accelerates gradually, the computer's default logic only requires upshifting to complete the acceleration. However, due to excessive force, the clutch may find during the upshift that a downshift is needed to achieve the intention of sudden acceleration, and then immediately performs a downshift. During this back-and-forth time, power cannot be transmitted smoothly, which easily leads to jerk.

How to set the unlocking sound for BMW?

BMW's locking sound cannot be set. Normally, a BMW does not make any sound when locking (only the sound of the lock engaging), and it cannot be configured. More details about BMW are as follows: 1. BMW (abbreviated as BMW) is a German automobile brand under the BMW Group, which includes the i, x, z, and pure number 4 model series, as well as the 1, 2, 3 series, and the M series (BMW's official high-performance modification division) based on improvements to each series. 2. Taking the BMW 2 Series as an example, it has two versions: the 2 Series Coupe and the 2 Series Convertible. In terms of body dimensions, its length, width, and height are 4454mm, 1774mm, and 1408mm, respectively. 3. The 2 Series models still feature a hidden B-pillar design, with the C-pillar having a steeper angle than the 1 Series Coupe, but it still differs significantly from the style of traditional coupe models, resembling more of a four-door sedan layout.

What does it mean when the airbag warning light is on?

If the airbag warning light continues to flash or stays on for more than 6-8 seconds after starting the vehicle, or if it flashes for 5 seconds and then stays on while driving, these situations indicate a potential fault in the airbag system. The airbag system typically consists of sensors, a microprocessor, an electronic control unit, an airbag cover and support ring, the airbag itself, and an airbag module. The illumination of the airbag warning light could be due to a malfunction in any of these components. Below are detailed explanations: 1. If the airbag warning light comes on while driving, remain calm and continue driving steadily to the nearest 4S shop or repair facility for inspection. If the entire airbag system needs replacement, do not feel it is not worth the cost. It is best to have this done at an authorized repair shop, as the market is flooded with counterfeit and refurbished airbags of questionable quality, which could lead to greater losses. 2. Due to manufacturers' secrecy regarding airbag technology and the lack of standardized regulations, many people believe that the lifespan of a car is the same as the design life of its airbags. However, this is not the case. The quality of airbags becomes unreliable after 8-10 years of use, so it is recommended to perform maintenance every 10,000-20,000 kilometers.
