What Causes the Jerking Sensation When Starting an Automatic Transmission Car?

Experiencing a jerking sensation when releasing the brake during startup can be attributed to various factors. For instance, internal transmission issues, such as excessive wear leading to gaps, can cause play during startup, resulting in a jerking sensation. The best solution to such problems is to replace the transmission fluid and perform a comprehensive transmission maintenance. Additionally, it's advisable to avoid aggressive driving in daily use to prevent accelerated transmission wear. This phenomenon is quite common in high-performance vehicles with substantial horsepower, especially those equipped with AT transmissions. During rapid acceleration, the engine speed increases extremely quickly, causing a noticeable impact when shifting from 1st to 2nd gear. Particularly when the accelerator is pressed hard, raising the engine speed to five or six thousand RPM or even higher, the transmission must downshift to reduce the speed from five or six thousand RPM to two or three thousand RPM to stabilize the engine speed. This process generates an impact, which is the so-called jerking sensation. During rapid acceleration, the jerking sensation in lower gears can become particularly intense.

What Causes the Exclamation Mark Light to Illuminate in a Car?

The reasons for the exclamation mark light illuminating in a car: 1. A red triangle with an exclamation mark in the middle is called a general fault light, which illuminates when the vehicle experiences a fault. Common issues include clutch overheating and fuel supply system malfunctions; 2. A red circular exclamation mark within brackets is the brake system warning light, which turns on when the handbrake is engaged; 3. A yellow exclamation mark with a line underneath within brackets is the tire pressure monitoring warning light, which illuminates only when the pressure in the vehicle's four tires is unbalanced or too low; 4. A yellow bulb with an exclamation mark inside is the lighting fault indicator light, indicating a fault in the car's light bulbs when it lights up; 5. A red steering wheel with an exclamation mark next to it is the steering system fault indicator light, which signals issues like power steering system failure, non-operation, or steering wheel lock when illuminated.

What are the 11 items in the Subject 3 simulated lighting test?

Driving at night without streetlights or under poor lighting conditions (headlights), meeting non-motor vehicles on narrow roads at night (low beam), following another vehicle closely in the same direction at night (low beam), meeting motor vehicles at night (low beam). Passing over an arch bridge or pedestrian crossing at night (alternating between high and low beams), navigating sharp turns or slopes at night (alternating between high and low beams), passing through intersections without traffic signals at night (alternating between high and low beams), experiencing a vehicle breakdown on the road at night that obstructs traffic and is difficult to move (parking lights and hazard warning lights), driving in foggy conditions (fog lights and hazard warning lights). Here are some key points: For example, use low beam when meeting or following another vehicle; use high beam when there are no lights or poor lighting conditions; alternate between high and low beams when passing through certain areas. Precautions: Before starting the test, always check the lights, as the previous examinee might not have reset them, which could affect your performance during the test; do not answer too quickly, listen carefully to the instructions, and wait until the voice prompt ends before acting, completing the action within 5 seconds; avoid operating too quickly to prevent the system from failing to detect the light switching signal.

What are the license plate letter codes for each city in Shandong Province?

Shandong Province's city-specific license plate letter codes are as follows: Lu A for Jinan, Lu B for Qingdao, Lu C for Zibo, Lu D for Zaozhuang, Lu E for Dongying, Lu F for Yantai, Lu G for Weifang, Lu H for Jining, Lu J for Tai'an, Lu K for Weihai, Lu L for Rizhao, Lu M for Binzhou, Lu N for Dezhou, Lu P for Liaocheng, Lu Q for Linyi, Lu S for Laiwu, Lu U as a supplementary code for Qingdao, Lu V as a supplementary code for Weifang, Lu W for provincial government agencies, and Lu Y as a supplementary code for Yantai. License plates, commonly referred to as vehicle tags, are plates affixed to the front and rear of vehicles. They are typically made of aluminum, sheet metal, plastic, or paper, and display the vehicle's registration number, registration region, and other relevant information.

Which gear should be used for automatic transmission cars when climbing a slope?

When climbing a slope with an automatic transmission, you should use the D gear or L gear. The L gear stands for low gear, and shifting to L gear locks the transmission in the 1-2 gear range. Climbing a slope requires greater torque to push the car upward and overcome the slope resistance. Owners of mid-to-high-end models prefer using the S gear for climbing slopes. Of course, the S gear provides very strong power, making it effortless for climbing. However, using the S gear for climbing can put the engine under high load, and prolonged use may damage the engine. The M gear is the manual mode for automatic transmission cars. Owners can manually shift up or down using "M+" and "M-", which is a more precise operation for climbing or overtaking based on actual driving conditions. Some models do not have L, D1, D2, M, or S gears. In fact, many modern cars are equipped with a hill-start assist system. Activating this function not only prevents rolling backward but also ensures a more stable start. For automatic transmission cars going downhill, you can use L, M, S, 1/2/3, or +/- gears. The main purpose is to keep the engine at a low speed while achieving a braking effect. Especially during long descents, keeping the car in D gear and continuously pressing the brake can easily cause the brake pads to overheat and lose braking effectiveness, which may seriously affect safety.

What is the starting RPM for an automatic transmission car?

For an automatic transmission car, an engine speed of 1200 to 1500 RPM is appropriate when starting. Since automatic cars already have an idle speed, it's sufficient to keep the RPM below 2000 when starting. When starting an automatic vehicle, especially for heavier models that require more torque to overcome inertia, the 'fixed throttle' method can be used: after engaging the clutch and shifting gears, slightly press the accelerator to stabilize the engine speed around 1500 RPM before gradually releasing the clutch using the 'fast, pause, slow' technique. This method ensures a smoother and more powerful start with reduced noise. When shifting gears in an automatic vehicle, shift to 2nd gear when the speed reaches 20 km/h and the RPM is between 1500-2000. Shift to 3rd gear when the RPM exceeds 2000, which typically corresponds to a speed near 30 km/h. Similarly, shift to 4th gear at 50 km/h. Shifting at 2000 RPM can lead to carbon buildup, so the fuel-efficient RPM range is 1500-2000. For a new automatic car during the initial break-in period, it's advisable not to exceed 2200 RPM. During the mid break-in period, keep the RPM below 3000, and it's also recommended not to exceed 3000 RPM in the later break-in stages.
