Why does an automatic transmission car shake when idling in D gear?

The reasons for an automatic transmission car shaking when idling in D gear are as follows: 1. The engine speed is too high, such as when the engine speed is too high during cold start. At this time, the torque converter transmits more power, resulting in greater impact force when shifting gears and more noticeable shaking. 2. The brake is not pressed firmly enough. When shifting into gear, the engine power is directly transmitted to the wheels. If the brake is not pressed firmly, the wheels may slightly move when shifting into D gear, causing the car to suddenly move forward and creating a stronger shaking sensation. 3. Releasing the brake too early. This is most common when waiting at a red light. After the light turns green, shifting into gear and releasing the brake to start, the car suddenly jerks forward when the brake is released. This is caused by releasing the brake too early, leading to abrupt power engagement. Additional Information: 1. It is normal for an automatic transmission car to have slight shaking when shifting into D gear, especially for AT transmissions equipped with a torque converter. This phenomenon is more noticeable. In cars with a torque converter, the engine power is transmitted to the transmission input shaft through the torque converter when in neutral. When shifting into gear, the transmission engages while the input shaft is rotating, causing an impact. 2. Some automatic transmissions use multi-plate clutches or dry clutches to transmit power between the engine and the transmission. When shifting gears, the clutch is completely disengaged, so there is no impact force, making it less likely to notice any shaking.

Is the first maintenance required after three months for a vehicle?

Is the first maintenance required after three months for a vehicle? Generally, since the engine, transmission, and other components of a new car are brand new, to maintain their service life, it is stipulated that the first maintenance should be performed at three months or 5,000 kilometers. This means that if only 2,000 kilometers are driven in three months, the first maintenance is still required. Similarly, if 5,000 kilometers are reached in two months, the first maintenance must also be done. The rule of three months or 5,000 kilometers applies, whichever comes first. More details are as follows: 1. The first maintenance for a car refers to its initial servicing, typically set at 5,000 kilometers/6 months (with some exceptions). Many brand dealerships, aiming to shorten the maintenance cycle for customers, now remind them to perform maintenance at 3,000 kilometers/3 months. The two values are based on whichever comes first. 2. The first maintenance is free of charge. However, if delayed, the maintenance will need to be paid for out of pocket, and it will be considered as forfeiting the warranty rights. Any future quality issues with the car will not be covered under warranty.

What is the adjustment method for disc brakes?

The adjustment of disc brakes generally involves adjusting the position of the brake pads. According to the instruction manual, the corresponding bolts can be adjusted for this purpose. More relevant information is as follows: 1. Disc brakes can be hydraulic, controlled by hydraulic pressure. The main components include the brake disc, wheel cylinder, brake caliper, and oil pipe. Disc brakes offer advantages such as rapid heat dissipation, light weight, simple construction, and easy adjustment. They perform particularly well under high loads with excellent high-temperature resistance, stable braking performance, and resistance to mud and water intrusion. In winter or under harsh road conditions, many cars use disc brakes with various types of brake discs, including flat brake discs, drilled brake discs, and slotted brake discs. Among these, slotted brake discs provide better braking performance and ventilation cooling. 2. Disc brakes are now widely used in passenger cars. Most passenger cars employ them on all wheels, while a few use them only on the front wheels, paired with drum brakes on the rear wheels to ensure higher directional stability during braking. In commercial vehicles, disc brakes are gradually being adopted in new models and high-end models.
