7-speed dual clutch transmission is based on manual transmission rather than automatic transmission, but it is an automatic transmission. Dual clutch must be an automatic transmission, so a 7-speed dual clutch is first an automatic transmission, and then it is also a manual-automatic transmission. Both manual-automatic transmission and dual clutch transmission are types of automatic transmissions, and they are upgraded products of automatic transmission vehicles, making driving more comfortable and adaptable to various road conditions. The following are precautions regarding dual clutch transmissions: 1. Advantages of dual clutch transmission: Dual clutch transmissions have fast shifting speed, small size and weight, and low energy consumption, so some performance cars use dual clutch transmissions. 2. Dual clutch transmissions do not have a torque converter. Improper operation can cause the clutch to slip, overheat, and result in unnecessary wear. The clutch will only disengage when the brake pedal is pressed.

I've driven quite a few 7-speed dual-clutch transmission cars, and they do support manual shifting function, so they can be considered as semi-automatic transmissions. However, their structure is completely different from traditional semi-automatic transmissions. Traditional semi-automatic transmissions use torque converters for gear shifting, providing better smoothness; while dual-clutch transmissions rely on two sets of clutch plates to switch gears, offering lightning-fast shifting speeds like racing cars. In traffic jams, dual-clutch transmissions tend to be jerky, but the manual mode with its plus/minus shifting is particularly thrilling. Many performance cars now use this type of transmission, and it feels especially exciting when driving on mountain roads with paddle shifters. However, for city driving, traditional semi-automatic transmissions are still more worry-free.

Strictly speaking, a 7-speed dual-clutch transmission also falls under the category of manual-automatic transmission because it has a manual shift mode. However, its core mechanical difference from traditional AT manual-automatic transmissions lies in the structure: dual-clutch systems use two sets of clutches that alternate to deliver nearly uninterrupted power during gear shifts, whereas AT transmissions rely on torque converters for power transfer. In practical driving, the manual mode of a dual-clutch transmission responds more sharply—gears snap into place instantly with a paddle shift, proving particularly effective during uphill overtaking. That said, in stop-and-go traffic conditions, its smoothness doesn't match that of conventional AT transmissions.

What are some methods for beginners to distinguish between the accelerator and brake when driving?

Here is a detailed introduction to methods for beginners to distinguish between the accelerator and brake: 1. Automatic transmission models: The leftmost pedal is the brake, and the rightmost is the accelerator. Automatic transmission models do not require manual gear shifting, as the car shifts gears automatically, so there is no clutch pedal—only the accelerator and brake, both controlled by the right foot. During driving, the left foot should not rest on the brake pedal. 2. Manual transmission models: The middle pedal is the brake, and the rightmost is the accelerator. Manual transmission models have three pedals, arranged from left to right as follows: clutch pedal, brake pedal, and accelerator pedal. For manual transmission models, the left foot should only be used to press the clutch pedal when shifting gears; during normal driving, the left foot should not rest on any pedal. Both the brake and accelerator are controlled by the right foot.

What Causes Car Shaking After Cleaning the Throttle Body?

Car shaking after cleaning the throttle body is due to the failure to perform idle speed reset learning after the cleaning process, which can lead to symptoms such as shaking, unstable idle speed, difficulty starting, and easy stalling. Below are specific details about the car throttle body: 1. Dirty throttle body causing idle speed shaking: When the air conditioning is turned on, the compressor also operates. Since the compressor is driven by the engine, its operation increases the engine load, which in turn increases the throttle opening and air intake. If the throttle body is not maintained for a long time, carbon deposits can easily form, obstructing the engine's air intake. This makes it difficult for the engine to drive the compressor, resulting in idle speed shaking. 2. Regular cleaning of the throttle body: If driving conditions are harsh, it is advisable to clean the throttle body regularly, recommended every 10,000 kilometers.

Is it mandatory to display a probationary sign during the probationary period?

It is mandatory to display a probationary sign during the probationary period. Below are the precautions to be taken during the driver's license probationary period: 1. Highway driving requires accompaniment: Probationary drivers are not allowed to drive on highways alone. If a probationary driver operates a motor vehicle on a highway during the probationary period, they must be accompanied by a driver who has held a driver's license for the same or a higher class of vehicle for more than three years. The accompanying driver should sit in the front passenger seat to provide guidance. Failure to have an accompanying driver or if the accompanying driver does not meet the requirements will result in a fine. 2. Display a probationary sign: It is mandatory to display a probationary sign while driving during the probationary period. If borrowing or renting a car during the probationary period, the probationary sign must also be displayed as required by regulations. Driving without the sign is not permitted. 3. Accumulating 12 penalty points: Accumulating 12 penalty points requires retaking the driving test. If a probationary driver accumulates 12 penalty points during the probationary period, their driver's license will be revoked, and they will need to reapply and retake the tests for subjects one, two, and three from the beginning.
