How to Change Transmission Fluid?

The method for changing transmission fluid is as follows: 1. Loosen the drain screw at the bottom of the transmission to drain the fluid and then refill: When the engine is turned off and the automatic transmission stops working, the oil pump becomes inactive, halting the circulation of automatic transmission fluid. Consequently, the fluid flowing in the valve body, pistons, torque converter, radiator, and cooling lines also stops abruptly, preventing it from flowing back into the oil pan. 2. Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. 3. Use a circulation machine to change the automatic transmission fluid: A smart circulation machine can perform dynamic fluid changes, filtering and cleaning sludge and impurities inside the automatic transmission. It ensures an equal exchange of fluid, completely replacing the old fluid in the transmission, thoroughly cleaning the internal circulation, and providing the transmission with a good internal working environment, thereby extending its lifespan.

How about the DCT wet dual-clutch transmission?

DCT wet dual-clutch transmission is relatively good, with the following advantages: 1. Seamless shifting: The dual-clutch transmission combines the advantages of manual and automatic transmissions, eliminating the torque converter and instead using two sets of clutches. The alternating operation of these two clutches achieves seamless shifting. 2. Full power utilization: Without a hydraulic torque converter, the engine's power can be fully utilized. Additionally, the alternating operation of the two clutches results in extremely short shift times, minimizing power interruption from the engine. 3. Lower fuel consumption: Due to more direct shifting and reduced power loss, fuel consumption can be reduced by more than 10%.

What does ION mean in a car?

ION in a car refers to the air purification function. When ION is activated, the air purifier starts working. The new ION system mainly consists of two components: 1. PM2.5 sensor: Function: It measures the PM2.5 content in the air inside and outside the vehicle, serving as the basis for whether to automatically activate ION and displaying the measured PM2.5 concentration on the car's screen. Location: The sensor is installed inside the vehicle's dashboard, to the right of the blower, on the right front A-pillar. 2. Negative ion generator: Function: It boosts the 12V low voltage to hundreds of volts of high voltage, ionizing the air to form negative ions for air purification, dust removal, deodorization, and sterilization. Location: Installed between the blower and the evaporator.

What is the difference between tire H and V?

The differences between tire H and V are as follows: 1. Different maximum speeds: Under load conditions, the maximum speed for tire V is 240 km/h, while for tire H it is 210 km/h. 2. Different performance: The performance of tire V is stronger than that of tire H. 3. Different resistance: When tires roll at high speeds, they generate heat due to squeezing and deformation, so the higher-grade tire V naturally has superior resistance. The functions of tires: Ensure good ride comfort and smooth driving for the car; Ensure good adhesion between the wheels and the road surface; Improve the car's traction, braking, and passing ability.

What is the ground clearance of the Bora?

The minimum ground clearance of the Bora is 126 millimeters. The minimum ground clearance of the Bora refers to the distance between the lowest point (excluding the wheels) and the supporting plane, which is used to indicate the vehicle's ability to pass over obstacles such as rocks and tree stumps without collision. A higher ground clearance for the Bora means better passability, but if the ground clearance is too high, the stability at high speeds will decrease. The Bora is the first independently designed model by FAW-Volkswagen and was first introduced to the Chinese market in 2001. The length, width, and height of the Bora are 4376 millimeters, 1775 millimeters, and 1446 millimeters respectively, with a wheelbase of 2688 millimeters. Generally, the ground clearance of sedans ranges between 110 millimeters and 150 millimeters, while SUVs have a ground clearance between 200 millimeters and 250 millimeters. However, the ground clearance of the Bora is not static; it also depends on the load condition. Therefore, changes in ground clearance should be considered based on the Bora's load variations. When selecting a vehicle, ground clearance can be one of the reference factors. The specific choice depends on the vehicle's intended use and the road conditions. For well-paved urban roads, a vehicle with lower ground clearance can enhance stability and comfort. If you frequently travel to remote areas or drive on poor road conditions, considering the vehicle's off-road performance, a higher ground clearance may be preferred to avoid scraping or damaging the undercarriage.

What is the function of a car's carbon canister?

The functions of a car's carbon canister are as follows: 1. Fuel saving: The carbon canister is filled with highly adsorbent activated carbon. Excess fuel vapor from the fuel tank is no longer released into the atmosphere but is instead directed into the activated carbon canister through a pipe, where the activated carbon adsorbs the fuel vapor. When the car is in motion, the carbon canister solenoid valve opens at the appropriate time to reintroduce the absorbed fuel vapor into the intake manifold, thereby saving fuel. 2. Reducing pollutant emissions: When the engine starts, the solenoid valve between the activated carbon canister and the intake manifold opens. The gasoline vapor inside the activated carbon canister is drawn into the cylinder by the vacuum in the intake pipe along with clean air to participate in combustion. This process helps reduce emissions.
