What does automatic transmission mean in a car?

An automatic transmission car generally refers to a vehicle that uses an automatic transmission (AT) to regulate speed. While driving, the control system of the automatic transmission automatically selects the appropriate gear based on the engine's speed and load, replacing the driver's subjective judgment of timing and gear-shifting operations. Below is relevant information about automatic transmission cars: 1. Automatic transmission cars typically use a hydraulic transmission device to replace the mechanical clutch in manual transmission cars, hence there is no clutch pedal. When the engine speed is low, the torque transmitted by the fluid is limited and insufficient to propel the car forward. When the gear lever is placed in the drive position and the brake pedal is released, as the accelerator is pressed and the engine speed increases, the transmitted torque increases, pushing the car forward. 2. In modern automatic transmission cars, the driver only needs to control the accelerator pedal. The computer analyzes signals such as engine throttle opening and vehicle speed collected by sensors, automatically controlling the transmission or shifting the transmission into different gears.

Does an automatic transmission car shake when shifting into reverse?

Automatic transmission cars may experience some shaking when shifting gears because the clutch differential is already engaged, and the engine is generating torque, so slight shaking is normal. However, if the shaking is severe, it could be due to the following reasons: 1. Low idle speed. 2. Dirty throttle body. 3. Dirty fuel injectors. 4. Severe engine carbon buildup. 5. Poor spark plug performance. Automatic transmission cars typically use a hydraulic transmission device to replace the mechanical clutch of manual transmission cars, so there is no clutch pedal. When the engine speed is low, the torque transmitted by the fluid is limited and insufficient to propel the car forward. When the gear lever is placed in the drive position and the brake pedal is released, as the accelerator is pressed and the engine speed increases, the transmitted torque increases, pushing the car forward.

How many times can a temporary license plate be issued?

Temporary license plates can only be issued once, but for new vehicles, the temporary plate can be extended up to 3 times for a total of 21 days. The validity period of a temporary license plate generally does not exceed thirty days. There are roughly four types: 1. Temporary license plates for administrative jurisdictions. 2. Temporary license plates for cross-administrative jurisdictions. 3. Temporary license plates for testing purposes. 4. Temporary license plates for special-type motor vehicles. Generally, a temporary license plate can only be issued once, but it can be extended up to three times in total. The validity period of a temporary license plate usually does not exceed one month. It is advisable to promptly visit the vehicle management office to complete the formalities for obtaining a permanent license plate.

What are the symptoms of a faulty hydraulic valve lifter?

When the engine is idling, a clicking sound can be heard from the middle of the engine, on the side of the hydraulic valve lifter, with an irregular pattern. After increasing the engine speed, the sound weakens or becomes chaotic, disappearing at high speeds. The main causes of abnormal noise from the hydraulic lifter are as follows: 1. Piston wear. 2. Valve oil leakage. 3. Insufficient oil pressure supply to the lifter. 4. Blockage of the piston and lifter body by oil sludge. When troubleshooting, parts that are severely worn or leaking oil should be replaced. Components with lighter wear can continue to be used after repair. When there is a valve tap noise in an engine equipped with hydraulic lifters, the oil level should be checked first. If the oil level is too low, oil should be added to the standard height.

How to engage the S gear in Golf 7?

Usage method of the S gear in Golf 7: The S gear is the sport mode. In sport mode, the transmission can shift freely, but the shifting timing is delayed, keeping the engine at high RPM for a longer time, allowing the car to move at high RPM in lower gears for an extended period, thereby achieving greater torque output and acceleration. Here is an introduction to the car's S gear: 1. The S gear allows the engine to maintain high RPM, with the transmission shifting up later and down earlier, enhancing the vehicle's power performance. 2. In S gear, the engine shifts at very high RPM, providing excellent power performance during rapid acceleration and overtaking. 3. Driving in S gear consumes significantly more fuel, resulting in poor fuel economy. Additionally, the S gear should not be used continuously during driving, as prolonged use can accelerate wear and tear on engine and transmission components, reducing their lifespan.

How Often Should the Handbrake Cable Be Replaced?

This component does not have a specific replacement interval or usage cycle. If the handbrake cable becomes loose, it can be tightened. If the handbrake cable is no longer functional, it needs to be replaced. Below is relevant information about the handbrake cable: 1. The handbrake cable is a component found in cars equipped with mechanical handbrakes. The mechanical handbrake has a handbrake lever behind the gear shift, and this lever is connected to the handbrake cable. 2. Over time, the cable of a mechanical handbrake may loosen, requiring the handbrake cable to be tightened. Otherwise, the car may roll when the handbrake is engaged. 3. If the handbrake cable is no longer usable, it should be replaced with a new one. 4. Some cars are equipped with an electronic handbrake system, which differs from the mechanical handbrake system. 5. The electronic handbrake has a button behind the gear shift and handbrake motors on the two rear wheels. When the button is pressed, the motors clamp the brake pads, preventing the car from rolling.
