Symptoms of not replacing the manual transmission fluid include: body shaking, gear shifting jerking; transmission high-temperature warning appearing on the dashboard; car stalling; unusual noises. Hazards of not replacing the transmission fluid for a long time: 1. Damage to the transmission's gear shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affecting the normal operation of the transmission, leading to damage to the transmission valve body. The methods for replacing transmission fluid are as follows: Loosen the drain screw at the bottom of the transmission to drain the fluid before refilling. Directly remove the transmission oil pan to drain and refill the fluid: This method is more thorough than the previous one, removing impurities at the bottom of the oil pan. Using a circulation machine to replace automatic transmission fluid: Dynamic oil change with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission.

Can Bodywork and Painting Be Done on Rainy Days?

No, rainy days can have a certain impact on vehicle painting. Here is some information about vehicle painting: 1. Reason: Rainwater generally contains acidity, and acid rain can significantly damage the car paint, easily causing oxidation of the paint surface and loss of gloss. 2. Consequences: The humidity after rain can affect the drying speed of the newly painted surface, but the reduced dust in the air due to humidity is beneficial for painting. 3. Precautions: (1) If the car has just been painted, avoid contact with water and dust on the newly painted areas; (2) It's best not to drive the car out on rainy days, as the fresh paint is still delicate and can leave marks when exposed to rain, which may be difficult to remove even with polishing. It's advisable to park the car in a garage at night; (3) Sunlight is not a concern as it only speeds up the drying process of the paint, which is beneficial; (4) Avoid exposing the newly painted areas to chemicals and oil stains.

What to Do When a Car is Stuck in Mud?

Solutions for a car stuck in mud: 1. Level the pit into a gentle slope, choose a position with less resistance for the front wheels, then use a more powerful gear or reverse gear to drive out, or organize manpower to assist; 2. Insert a hard wooden pole into the steel rim, use a wooden block or stone as a fulcrum, apply human force on the lever end to lift the wheel, then fill the space under the wheel with wooden planks or stones, remove any obstructing mud or debris, lower the wheel back to the ground, and drive out using a low gear; 3. Drive a wooden stake or insert a wooden pole under the wheel at an appropriate distance in front of the car, tie one end of a thick rope to the stake, pass the other end through the holes in the inner and outer steel rims of the driving wheel, secure it to the tire, then slowly start moving forward in first gear. As the rope winds between the two wheels, the car will be pulled out.

Should the Clutch Be Depressed When Shifting Gears While Driving?

When shifting gears while driving, it is necessary to depress the clutch, especially for car transmissions equipped with synchronizers. Without depressing the clutch, shifting gears becomes difficult. Fully depressing the clutch during gear shifting is to completely disconnect the engine from the transmission gears, allowing the gear lever to change the gear set before re-engaging. During the gear shifting process, if the clutch is not fully depressed, there will be a significant speed difference between the shifting gear set and the transmission gear set, making smooth meshing impossible and potentially causing damage to the gearbox. The clutch is located within the flywheel housing between the engine and the transmission. The clutch assembly is secured to the rear plane of the flywheel with screws. The output shaft of the clutch serves as the input shaft of the transmission. Typically, the clutch is installed together with the engine crankshaft's flywheel assembly, acting as the component that cuts off and transmits power between the engine and the vehicle's transmission system.

What is the fuel tank capacity of an average car?

Generally, the fuel tank capacity of small cars ranges from 35 to 45 liters, while that of medium-sized cars ranges from 55 to 75 liters. A full tank typically allows a driving range of approximately 500 kilometers. The size of the fuel tank correlates with the vehicle's displacement: cars with higher fuel consumption have larger tanks, while those with lower consumption have smaller ones. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the tank capacity specified by car manufacturers measures from the bottom of the tank to the safety level, leaving some space between the safety level and the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing from the tank. If fuel is added up to the tank opening during refueling, the actual amount of fuel may exceed the calibrated tank capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, which is marked with 'E' and 'F'. When the needle approaches 'E', it indicates low fuel, while nearing 'F' means the tank is nearly full.

What to Do If There's a Car in Front During Straight-Line Driving in Subject Three Exam?

Upon hearing the "straight-line driving" voice command, if there is a car blocking the exam vehicle ahead, the examinee should prioritize following the examiner's instructions. Typically, in such situations, the examiner will require the examinee to maintain an appropriate distance from the car in front and complete the straight-line driving operation in the current lane. Additional details are as follows: 1. Straight-line driving, as the name suggests, means keeping the driving path in a straight line. After hearing the voice prompt "Please maintain straight-line driving," the examinee should look straight ahead, control the steering wheel with both hands, and keep the vehicle driving straight. 2. To keep the vehicle driving straight, one must learn to focus on a distant point on the road, making it less likely for the vehicle to deviate.
