Why does the transmission get hot?

Transmission gets hot due to the following reasons: 1. Insufficient lubricating oil in the transmission; 2. The selected lubricating oil grade does not meet the requirements; 3. Bearings are assembled too tightly; 4. Gaskets and washers are assembled too tightly; 5. The meshing clearance of newly replaced gears is too small. The transmission, also known as the gearbox, is a mechanism used to change the speed and torque from the engine, and can fix or change the gear ratio between the output shaft and the input shaft. The functions of the transmission are: 1. To change the transmission ratio and expand the range of torque and speed variation of the driving wheels; 2. To enable the vehicle to reverse while the engine's rotation direction remains unchanged. Types of transmissions include: 1. Manual transmission; 2. Automatic transmission; 3. Semi-automatic transmission; 4. Continuously variable transmission.

How to Resolve the MG Engine Emission Warning Light Illumination?

Perform three consecutive cycles of starting and shutting off the vehicle, or alternatively, disconnect the negative terminal of the engine battery, wait for 30 seconds, and then reconnect it. If the warning light illuminates while driving, immediately reduce speed and proceed to the nearest maintenance service station for inspection. If the vehicle fails to start after the warning light comes on, this is typically caused by a malfunction in the fuel pump or ignition system. In such cases, directly call for a tow truck.

How to Choose a Car: What to Look For?

Here are the key aspects to consider when choosing a car: 1. Exterior Inspection: When selecting a new car, you can request two vehicles of the same model for comparison. Focus on examining the gaps between the bumper and body, door seams, and front/rear bumper alignment. Open the doors to check for color consistency between interior and exterior paint. Paint quality is best evaluated under natural daylight, as it reveals all imperfections. If inspecting in a showroom, angle the car against sunlight for similar results. A qualified paint job should be smooth, free of orange peel or water ripple defects, with no color mismatch on vulnerable areas like bumpers, door edges, and side mirrors. For metallic or pearl-effect paints, assess the even distribution of aluminum flakes or mica particles. 2. Mechanical Components: Start with the engine. A well-functioning engine should be leak-free, respond quickly during startup, run smoothly without vibration, and produce consistent noise without sharp or irregular sounds. During cold starts, idle RPM should be around 1,000, dropping to approximately 780 when warmed up. Light acceleration should yield prompt response without knocking or loose sounds. The engine hood should show minimal vibration when touched, and cabin noise should be barely audible. 3. Doors and Wipers: Proper doors should operate smoothly with uniform force, no strange noises, intact rubber seals, and noticeable airtightness when closed. The final closing motion should have a slight suction effect. Inspect lower door frame paint for wear or dirt - these may indicate poor storage conditions. Power windows should feature anti-pinch protection on all doors. 4. Audio System: Test electric seats and parking sensors for proper function. Ensure the antenna is properly installed as missing antennas degrade radio reception. 5. Test Drive: While previous checks were static, a test drive is essential. After starting the engine and adjusting mirrors, note these driving characteristics: steering should feel responsive with good road feedback. When releasing the wheel at medium-low speed, the car shouldn't deviate more than 5 meters over 500 meters. Manual transmissions should shift smoothly; automatic transmissions should change gears without noticeable jerks. Drive over uneven roads to check for abnormal noises. The steering wheel should self-center after turns. New cars may have slight throttle lag initially, but acceleration should become linear afterward. With AC compressor engaged, throttle response shouldn't degrade significantly, and cool air should be felt within 10 seconds.

What does it mean when the appointment for Subject 2 test shows 'not attended training'?

It means that the applicant for driver's license training has not completed the required training hours for Subject 1, Subject 2, and Subject 3. Only after completing these can they schedule the test. Duration: Subject 1 training requires 12 sessions, Subject 2 requires 16 sessions, Subject 3 road driving training must cover at least 300 kilometers and 24 sessions, and Subject 4 (safe and civilized driving) requires 10 sessions. Each session lasts 60 minutes, with effective training time not less than 45 minutes. The total training hours for C1 and C2 licenses are 62 and 60 hours respectively, both about 10 hours less than previous requirements. Each session is 60 minutes, with effective teaching time not less than 45 minutes. Each trainee's daily classroom learning and practical operation time must not exceed 4 sessions. Standards: The timing for Subject 1 system learning starts the training clock. For Subjects 2 and 3, system check-in photos plus training mileage are required—none can be omitted. Failure to meet these standards will prevent the applicant from scheduling the test.

What are the methods for repairing aged car lamp covers?

First, clean the headlights as thoroughly as possible using water and a damp cloth, removing any areas where stubborn stains have not yet formed to reduce subsequent workload. Use six different grades of sandpaper ranging from coarse to fine for sanding. Thoroughly atomize the coating solution using the atomizer in the refurbishment tool. Ensure the steam emitted from the atomizer is continuous and uniform before applying the coating to the headlights.
