Can Manual Transmission Use Automatic Transmission Fluid?

Manual transmissions cannot use automatic transmission fluid for the following reasons: The viscosity of manual transmission fluid is higher than that of automatic transmission fluid, which helps to better lubricate the friction surfaces of manual transmission gears. The fluidity of automatic transmission fluid is higher than that of manual transmission fluid, allowing for faster and more stable transmission of engine power. The heat dissipation capability of automatic transmission fluid is superior to that of manual transmission fluid, preventing excessive temperatures that could reduce lubrication effectiveness and damage moving parts of the automatic transmission, such as causing component jamming, clutch slippage, or seal leakage. The methods for changing transmission fluid are as follows: Loosen the drain screw at the bottom of the transmission to drain the old fluid before refilling. Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the previous one, as it allows for the removal of impurities at the bottom of the oil pan. Use a circulation machine to change automatic transmission fluid: A smart circulation machine can perform dynamic fluid changes, filtering and cleaning sludge and impurities inside the automatic transmission.

What Causes the Entire Car to Shake When Braking?

The reasons for the entire car shaking when braking are: 1. Tire deformation; 2. Incorrect tire dynamic balance; 3. Vehicle transmission system failure; 4. Worn or loose ball joints or detached rubber sleeves at connection points; 5. Twisted or deformed drive shaft; 6. Uneven brake discs; 7. Overly loose or tight power steering belt. Braking, also known as stopping, refers to the action of halting or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The methods to address the entire car shaking when braking are: 1. Check whether the ignition coil has leakage or internal short circuit; 2. Check whether the ignition coil wiring plug is loose or has poor contact; 3. Check whether there is corrosion at both ends of the battery; 4. Check whether the vehicle body grounding is good.

Where is the rearview mirror heating button on the MG ZS?

The rearview mirror heating button on the MG ZS is located on the far right of the air conditioning switch panel. The last button in the first row is the rearview mirror heating button, which is the same button as the rear window heating. The icon is a rectangle with three upward wavy lines. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rainwater or fog, eliminating the need for the driver to frequently wipe the mirror manually, thereby reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is needed, as the driver's side has a control button. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within minutes, typically between 35-60 degrees. Heat is then emitted from both left and right rearview mirrors. Simultaneously, due to the rising temperature and evaporation, water droplets on the mirror surface shrink, and fog gradually disappears, effectively defogging and deicing the mirror. However, in heavy rain, its effectiveness may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves electric heating wires embedded in the mirror, which consume significant power. When using this function, ensure the car is running. Avoid activating rearview mirror heating while the car is stationary to prevent draining the battery, which could hinder starting the vehicle. Other methods for defogging rearview mirrors include: Opening windows slightly to create airflow between the inside and outside of the car, reducing the temperature difference and allowing fog to dissipate gradually. Adjusting the car's air conditioning to the appropriate setting to blow warm air for defogging.

What is the normal cylinder pressure?

Normal cylinder pressure varies depending on the vehicle series: 1. Japanese cars are around 1100kpa; 2. European and American cars are around 1200 to 1300kpa. Insufficient cylinder pressure can lead to excessive carbon deposits, severe engine shaking, increased fuel consumption, and even engine overheating, making it difficult to start the car. Causes of insufficient cylinder pressure include: 1. Piston ring misalignment, excessive wear, and insufficient cylinder lubrication; 2. Poor sealing or damage to the cylinder gasket; 3. Excessive flatness of the two contact surfaces between the cylinder head and cylinder block, resulting in poor sealing; 4. Poor sealing of intake and exhaust valves; 5. Malfunction in the car's cooling system leading to insufficient engine heat dissipation.
