What causes a car to start but not shift gears?

What are the tips for driving during the break-in period of a new car?

During the break-in period of a new car, it is advisable to shift to lower gears in advance to protect the engine. Here are some driving tips for the break-in period of a new car: 1. Before driving: After starting the engine, do not abruptly increase the RPM or continuously press the accelerator pedal aggressively. Avoid running the engine at constant high (or low) speeds; it is better to operate the engine at moderate RPM, generally not exceeding 80% of the maximum RPM. 2. While driving: Do not exceed the maximum speed for each gear; avoid prolonged high-speed driving or accelerating while in high gear. Driving speed should generally be controlled within 70% of the maximum speed for each gear. Avoid driving at a single speed for extended periods, whether fast or slow, and do not drive slowly while in high gear. 3. Other considerations: Shift gears promptly according to road conditions, taking into account the reduced engine power during the break-in period. Shift to lower gears in advance and avoid forcing the use of high gears to prevent excessive engine load. The load during the break-in period should not exceed 70% of the rated capacity, and towing trailers or other vehicles is not allowed. For passenger cars during the break-in period, the engine RPM should be controlled within 2500~4000 RPM, and the maximum speed should be kept below 90 km/h. Avoid emergency braking to prevent damage to mechanical components. Gentle use of the brakes can help with the break-in process and extend the lifespan of the braking system. To shorten the break-in time for the brakes as much as possible, during the first 200 km of driving, you can appropriately increase the number of brake applications to accelerate the break-in of the brakes. Fuel and oil selection during the break-in period: To prevent accelerated wear of components due to knocking during the break-in period, use high-quality gasoline with a higher octane rating. Since the internal components of the engine have smaller clearances during the break-in period, choose high-quality, low-viscosity oil to ensure good lubrication of the friction surfaces, and avoid using engine wear-resistant additives.

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.
