What Causes Transmission Overheating?

Transmission overheating reasons: Insufficient lubricating oil in the transmission or using lubricating oil with an incorrect specification, excessively tight bearing assembly, excessively tight gasket and washer assembly, or excessively small gear meshing clearance in newly replaced gears. To avoid affecting usage, it is recommended to promptly contact a 4S shop for repair. Below is additional information: 1. When stopping to inspect during driving: Touch various parts of the transmission housing with your hand to check the temperature. If the temperature is bearable to the touch, the oil temperature is normal; if it is unbearable, it indicates an overheating issue. To confirm transmission overheating, first check the lubricating oil level. If it is insufficient, replenish it as required; if the oil is too thin or deteriorated, replace it. If dry friction is caused by excessively small assembly clearance (e.g., overheating near the bearing seat due to excessively tight bearing assembly), disassemble and inspect accordingly, then reassemble following the specifications. 2. Precautions for transmission overheating repair: The normal operating oil temperature for an automotive transmission is 80°C~90°C. Excessive transmission operating temperature can cause premature oil oxidation, especially when the transmission operating temperature exceeds 120°C~200°C, as the antioxidant additives in the oil become ineffective, drastically accelerating oil oxidation. Transmission overheating can be judged based on the overheating location. The causes of overheating are generally: excessively small gear meshing clearance; bent gear shafts or misaligned or non-parallel housing shaft holes; insufficient gear oil or too low viscosity; excessively tight bearing or gasket assembly, etc. If transmission overheating is confirmed through inspection, repair accordingly.

Is it acceptable to steer with one hand in Subject 2?

Steering with one hand in Subject 2 does not result in point deduction. However, using one hand to steer can make it difficult to gauge how much the wheel has been turned, especially during reverse parking. Additionally, if the steering wheel is heavy, one hand may not be sufficient, leading to delays and potential wheel alignment issues. Below are precautions for Subject 2: 1. Pass Subject 2 within three years: After completing Subject 1, you must pass Subjects 2 and 3 within three years. Failure to do so will invalidate your results, requiring you to re-register for Subject 1. Under new regulations, Subjects 2 and 3 each allow five attempts. If you fail all five attempts, you must retake Subject 1. 2. Failing the test: If you fail Subject 2 on the first attempt, you are allowed one retake. If you skip the retake or fail it again, the test ends, and you must reschedule after ten days. Within the validity period of your driving skill permit, you can schedule Subjects 2 and 3 road tests up to five times. Failing the fifth attempt invalidates all previously passed subjects.

What causes the clicking sound before the Corolla fails to start?

The clicking sound without ignition may be due to insufficient voltage in the car battery. When the battery does not provide enough power, it cannot drive the engine to reach the starting speed. The clicking sound during startup is caused by the repeated engagement between the magnetic coil and the relay. Below are the reasons and solutions: 1. Battery aging: Insufficient voltage may be caused by the battery aging over time, leading to a continuous reduction in stored power. Additionally, some car owners listen to music or turn on the air conditioning when the car is not running, which significantly drains the battery, making it more prone to losing power. 2. Engine: Excessive carbon buildup in the intake pipe, throttle valve, idle motor, and other parts can prevent the engine from achieving the required air-fuel mixture ratio, causing the vehicle to fail to start and resulting in the clicking sound from the magnetic coil and starter relay. Similarly, insufficient fuel supply in the fuel system has effects similar to excessive carbon buildup in the intake pipe, also preventing the engine from achieving the required air-fuel mixture ratio. 3. Magnetic coil: A malfunction in the starter motor, primarily the magnetic coil's inability to maintain engagement, fails to provide the starting torque, leading to the engine's failure to start accompanied by a clicking sound. A fault in the ignition system directly prevents the engine from starting. If the ignition key remains in the start position, causing the starter relay to repeatedly engage, it will also produce a clicking noise. 4. Starter brush damage: If the starter brush is damaged, there won't be enough voltage (rated voltage), making it difficult for the starter to operate. Issues with the starter itself, such as the starter flywheel not swinging, can prevent the starter and engine from connecting. For fuel system faults, disconnect the oil pipe connector on the engine, turn on the ignition switch, and observe if there is fuel flow when the dashboard lights up (without the starter running). If there is fuel flow, it indicates a problem in the fuel supply system; if not, further checks on other parts are needed. The specific fault phenomenon requires inspection at a 4S shop or professional repair shop to identify the root cause.

How to Reverse Park in One Go Without Adjustments?

The techniques for reversing into a parking space in one go without adjustments are as follows: 1. First, adjust your rearview mirrors: This will help you see the position of your car's rear wheels, making the reversing process more manageable. Additionally, stay calm during the process and maintain a slow speed. During the actual test, as long as the car doesn't stop or stall, any slow speed is acceptable. A slower speed gives you more time to control the steering, ensuring the car remains stable and the process is completed smoothly. If the car stops while reversing, the system will mark it as a failure. Therefore, practice finding the right speed sensation at the training ground to successfully park. 2. The second tip is about steering: Many beginners find it uncomfortable to steer, especially when reversing. Normally, turning right means the car goes right, and turning left means it goes left—this also applies to the rear of the car. Turning left steers the rear left, and turning right steers the rear right. This takes some time to get used to, but it's not difficult. 3. The third tip involves finding reference points: During training, people often use objects like a rock or a patch of grass as reference points for reversing. However, in the test area, these markers won't be available. Learn to align the lines with the car and follow the instructor's methods instead of sticking to your own approach. Pay attention to steering control when reversing into the parking space. Ideally, keep the rear wheels about 30 centimeters from the corner—this is the safest distance. Any less or more may lead to crossing the line.

What are the requirements for hill start?

The requirements for hill start are as follows: 1. Maintain the correct driving posture, pay attention to various traffic conditions on the road ahead, and do not lower your head to look. 2. The operation sequence is to step on the clutch with the left foot, gradually press the accelerator pedal with the left foot to shift into low gear, and gradually press the accelerator pedal with the right foot. When the engine sound changes or the body slightly shakes, quickly release the handbrake, and then slightly press the accelerator pedal while slowly lifting the clutch pedal. 3. Do not immediately release the clutch pedal, but first apply the throttle before releasing the clutch. Because the resistance of the car is greater when going uphill, the power required for starting is also greater. 4. The key point is to master the timing of releasing the handbrake. If released too early, the vehicle will roll backward; if released too late, it will cause the engine to stall. The best time is when the clutch pedal is lifted to the semi-engaged position and the engine sound changes, release it immediately. 5. The essentials of hill start can be summarized as: when the sound changes and the car shakes slightly, pause slightly, quickly apply the throttle and release the brake, adjust the throttle according to the slope, and avoid rolling back, surging, or stalling.
