What happens if too much transmission fluid is added?

Effects of adding too much transmission fluid: 1. The fluid level will be too high, and during driving, the fluid easily contacts rotating components. The agitation of the fluid by these components can create bubbles, which, when drawn into the oil pump, lead to abnormal oil pressure and reduced lubrication effectiveness. 2. It can cause the drainage holes on the control valve to become blocked, resulting in poor drainage and causing gear shift shocks. 3. The resistance experienced by rotating gears increases, affecting the transmission's efficiency. Transmission fluid is used to keep the gear system clean in automatic transmissions and serves to lubricate and prolong the life of the transmission components.

What are the methods to deal with car scratches?

After treating with a compound, apply wax in the same direction from the inside out. The functions of car wax include the following three points: 1. Waterproofing effect: Water droplets remaining on the car body surface can, under the effect of focusing, reach temperatures of 800-1000°C at the focal point, greatly affecting the paint quality and lifespan. Water droplets can also cause rust on exposed metal surfaces. 2. High-temperature resistance: It effectively reflects incident light from different directions, preventing the paint or base color from aging and discoloring due to incident light. 3. Anti-static effect: The principle is to block the friction between dust and the car's metal surface. Due to differences in the thickness of the wax layer and the wax's own adhesion ability, the anti-static effect varies to some extent.

What does braking mean?

Braking refers to the deceleration braking method employed during normal vehicle operation, commonly known as the foot brake. Below are specific introductions regarding braking: Differences between service brake and parking brake: 1. Different environments: The service brake is typically used during normal vehicle operation, while the parking brake is used when the vehicle is parked to prevent it from sliding. 2. Different principles: The service brake transmits mechanical force from the brake pedal to hydraulic pressure, which then travels through pipelines to the brake for stopping, whereas the parking brake operates by connecting steel cables to the brake shoes for braking.

What are the symptoms of carbon buildup in the engine?

The symptoms of carbon buildup in the engine are as follows: 1. Engine acceleration weakness: When carbon deposits accumulate severely, the engine will experience weak and sluggish acceleration, accompanied by abnormal engine shaking and increased fuel consumption. 2. Engine knocking: If carbon buildup in the combustion chamber becomes too severe, it will invisibly increase the compression ratio of the engine cylinders, which may lead to premature combustion of the air-fuel mixture and cause knocking. 3. Cylinder scoring: If carbon deposits accumulate near the piston rings or if carbon from the cylinder head or valves falls onto the piston rings, it can cause scoring of the engine cylinders. In severe cases, it may even lead to a "seized cylinder" phenomenon.

What is Car Torque?

Car torque refers to the rotational force output from the crankshaft end of the engine. Here are specific details about car torque: 1. Relationship between torque and the engine: Under fixed power conditions, it is inversely proportional to engine speed. The faster the speed, the smaller the torque, and vice versa, reflecting the vehicle's load capacity within a certain range. 2. Relationship between torque and horsepower: With the same displacement, higher torque indicates a better engine. A significant part of the 0-100 km/h acceleration time depends on the car's torque. Horsepower, which is the car's power, determines how fast a car can ultimately go, depending on how high the horsepower limit is. For family cars, the engine's maximum torque should occur at very low speeds, while maximum horsepower appears at relatively higher speeds.

What are the symptoms of transmission abnormalities?

Symptoms of transmission abnormalities: 1. Transmission slipping: When accelerating the car, you may notice the engine revving without power transfer, or feel weak acceleration response, significantly worse than before. The vehicle may drive normally on flat roads but struggles noticeably when climbing hills. 2. Transmission fluid leakage: This condition makes the vehicle difficult to start, and while engine RPM increases when pressing the accelerator, the acceleration effect becomes significantly weaker. This is likely caused by insufficient gear lubrication due to fluid leakage. 3. Gearshift hesitation: Shifting gears may feel noticeably rougher with severe jerking. Drivers might feel strong impacts during gear changes, sometimes even causing hand numbness. If this occurs occasionally, it usually indicates improper shifting timing.
