Does a CVT transmission have jerking sensations?

CVT transmission having jerking sensations is a normal phenomenon. The jerking sensation in the transmission is caused by the inertia of the moving parts inside the engine. Below are the reasons for jerking sensations in a CVT transmission: 1. Upshift jerking, because the transmission's response speed is not fast enough, and the upshift speed cannot keep up with the throttle input, resulting in a jerking sensation during the moment of gear shift. 2. Downshift jerking, due to the intervention of the energy recovery system. Once the driver releases the throttle pedal or presses the brake pedal, the generator immediately starts working with the engine, imposing a burden on the engine, affecting the engine speed, and causing a mismatch between the engine speed and the clutch plate speed, resulting in a jerking sensation. 3. Low-speed jerking, because when driving at low speeds, the gear frequently shifts between first and second gears, and the clutch continuously engages and disengages, making it unable to smoothly complete power transmission in a short time, leading to low-speed jerking. There will be a jerking sensation during startup and at low speeds, which occurs when the turbocharger intervenes at low RPMs, affecting the engine speed.

I've been driving a CVT transmission car for five years, and most of the time it's been incredibly smooth, without any jerking sensation—it feels like driving on clouds. However, last winter during low-speed traffic congestion, the car suddenly lurched forward, as if being tugged. I suspect it might have been due to dirty transmission fluid or the steel belt not being properly secured. Modern CVTs use computer control to adjust the steel belt's position, but errors can occur on slippery roads or during sudden acceleration. After changing the transmission fluid, such issues became much less frequent. Overall, CVTs are designed to eliminate jerking and are far superior to old-style automatic transmissions, as long as you perform regular maintenance and avoid stomping on the gas pedal on steep slopes. As a car owner, paying attention to these small details can help extend the vehicle's lifespan.

Will Water Enter the Car If It Doesn't Stall After Wading?

If the car doesn't stall after wading, the engine is not flooded, but other parts of the car may have taken in water. When wading through water, maintain a low speed, as driving too fast can increase the actual wading depth. It's also best not to stop or shift gears during this time. Even if the car doesn't stall after wading, maintenance checks are still necessary. Drive through the water at a steady speed in a low gear with moderate to high throttle, as excessive speed can create large waves or splashes, increasing the actual wading depth and making it more likely for the car to encounter problems. If the car stalls unexpectedly after wading, do not attempt to restart it immediately. Instead, take measures to tow the car to a safe area with less water as soon as possible. It's important to remove moisture from the brake pads promptly, especially for cars with drum brakes, as failure to do so can result in loss of braking after wading, posing a significant safety hazard.

Why is the warning light flashing?

The reasons for a flashing warning light: 1. Check if the emergency hazard lights are activated (whether the red triangle button is pressed); 2. Verify if any car door is not properly closed; 3. The flashing switch might be damaged. If the issue persists after checking these points, it's recommended to visit a 4S shop for inspection. Various warning lights on a vehicle mainly include: engine malfunction indicator light, low oil pressure warning light, coolant temperature warning light, engine charging indicator light, brake system fault light, ABS system fault light, seat belt reminder light, airbag fault light, power steering warning light, tire pressure monitoring warning light, etc.

When do tires generally need to be replaced?

When tires are severely worn, bulging, have exceeded a certain age limit, or when nails puncture the tire sidewalls, they need to be replaced. Failure to replace tires can lead to dangerous blowout situations while driving, especially at high speeds where blowouts can be particularly severe. Additionally, it is important to regularly clean small stones or sharp objects from the grooves of car tires. Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high or low temperatures during operation. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning properties.

Can I register a car bought in another province in my home province?

You can register a car bought in another province in your home province. The process for purchasing a car in a different location and registering it locally is as follows: 1. After purchasing the car in another location, ensure that the materials provided by the 4S store are complete, such as the car invoice, vehicle certification, maintenance manual, etc.; 2. Compulsory insurance can be purchased at the 4S store, while other commercial insurance can be bought in two ways: first, by purchasing insurance at the point of sale, but be sure to choose a large insurance company, and second, by purchasing insurance at the registration location; 3. Since the car is purchased in another location, it will definitely need to be driven back to your home location. The owner must obtain temporary license plates for the new car, specifically temporary plates for out-of-province use. Note that after obtaining the temporary plates, the new car must be driven back to your home location within the validity period of the temporary plates. Otherwise, if the temporary plates expire, you must apply for them again, with a maximum of three applications allowed; 4. Once the new car arrives in your home location, the owner must go to the local tax bureau to pay the vehicle purchase tax, and then can proceed to the vehicle management office to register the new car. China's regulations on new car registration require that as long as the vehicle has the four basic documents—a formal invoice, certification, purchase tax, and compulsory insurance—it can be registered.

How to start the Buick GL8 when the remote key is out of battery?

Is the GM L2B One of the Top Ten Engines?

General Motors' L2B engine is one of the "China Heart" Top Ten Engines, manufactured by Shanghai GM Dongyue Automotive Powertrain Co., Ltd., making it a domestically produced engine. Models such as the Baojun 730 and Wuling Rongguang are equipped with the L2B series engine. The Baojun 730's engine has a maximum power output of 105 kW and a maximum torque of 177 Nm, while the Wuling Rongguang's engine delivers a maximum power of 73 kW and a maximum torque of 135 Nm. For daily maintenance of the GM L2B engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will degrade over time. After a certain mileage, performance deteriorates, leading to various engine issues. To prevent malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level. As oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter element or open the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication points, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger quantities precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
