What oil should be added to a car transmission depends on the type of transmission: manual transmissions require gear oil, while automatic transmissions need transmission fluid. The functions of transmission oil are: 1. To change the transmission ratio and expand the range of torque and speed variations of the driving wheels; 2. To adapt to frequently changing driving conditions, allowing the engine to operate under favorable circumstances; 3. To enable the car to reverse while the engine's rotation direction remains unchanged; 4. To interrupt power transmission, facilitating gear shifts or power output in the transmission. The correct maintenance methods for an automatic transmission include: 1. Checking the automatic transmission fluid by testing its viscosity between fingers and replacing it if discolored or with a burnt smell; 2. Inspecting the manual gear selection mechanism, ensuring the linkage or cable connecting the gear lever to the manual valve is properly adjusted, with the manual handle position corresponding to the spring clip position inside the automatic transmission; 3. Adjusting the brake bands, where all adjustment structures need to be fine-tuned to compensate for wear; 4. Checking the braking performance of the parking gear, and inspecting and repairing if there is no braking performance in the parking gear.

What Causes the Heat Below the Car Gear Shift?

Automatic transmission vehicles may experience heat below the gear shift lever for the following reasons: 1. Poor heat dissipation: This is typically caused by inadequate heat dissipation, with the simplest explanation being a malfunctioning radiator. 2. Damaged solenoid coil: The issue might also stem from a faulty solenoid coil inside, which can be resolved by replacing the coil. 3. Normal phenomenon: If there are no faults and the heat is not excessive, it is considered normal due to the engine's proximity below, which emits heat. However, if the temperature becomes excessively high, it is advisable to visit a professional repair shop for inspection.

Is It Okay to Start a Car in Second Gear?

Occasionally doing so is fine, but prolonged use can harm the vehicle. Starting in second gear can work well if enough throttle is applied and the clutch is controlled properly, but it significantly wears the clutch. Below are the hazards of starting in second gear: 1. Clutch damage: Frequent second-gear starts can damage the clutch. Research shows that the friction heat temperature of the clutch plate is 60 degrees higher when starting in second gear compared to first gear. The heat generated from clutch plate friction is the main cause of wear. If the car feels sluggish when starting in second gear, it indicates clutch plate wear. Therefore, whether it's a heavy truck or a small car, or whether the vehicle is loaded or empty, starting in first gear is necessary to minimize clutch wear. However, once the vehicle is moving, shifting to second gear is acceptable. 2. Engine wear: The gear ratio of second gear is closer to first gear, so the wear is relatively less severe. Starting in higher gears increases clutch wear. Additionally, starting in second gear places a heavier load on the engine, and incomplete fuel combustion can lead to carbon buildup, causing engine damage. From a vehicle maintenance perspective, it's best to start in first gear.

Why does the car remote key flash a red light when pressed?

Car key flashing red light when pressed is due to the key battery being dead. It is recommended that the owner replace the battery promptly. Below is relevant information: 1. Car key: A car key refers to the tool used to start and stop the car. Modern car keys use a chip, which is part of a magnetic chip system. The reading coil in the car's ignition lock cylinder reads the chip in the key, and each chip has a fixed digital information. A remote key allows the user to lock and unlock the car doors from a distance without inserting the key into the lock. 2. Principle of car anti-theft lock: The logic of car engine anti-theft is that when the ignition switch is turned on, the key transponder and the anti-theft controller form the first information exchange. If the identification code between the key and the chip does not match, the anti-theft controller will not continue to communicate with the ECU, and the ignition system and fuel injection system circuits will remain open, preventing the engine from starting.

What is the normal voltage range for an oxygen sensor?

The normal voltage range for an oxygen sensor is between 0.1-0.9V, with an average typically around 0.4-0.5V. Additional knowledge: 1. Relationship between voltage frequency and sensor condition: The faster the voltage frequency changes, the better the sensor's condition. If the voltage remains at 0V or 1V without any change, it indicates severe aging of the oxygen sensor, and it should be replaced promptly. 2. Difference between front and rear oxygen sensors: Normally, the front oxygen sensor's signal is higher than the rear oxygen sensor's. If both sensors show the same oxygen concentration data, it indicates that the three-way catalytic converter has failed.
