How Many Gears Does the Corolla Transmission Have?

The Corolla manual transmission uses a 5-speed manual and a 6-speed manual, while the automatic transmission uses a CVT (simulating 8 gears) and an E-CVT. The continuously variable transmission (CVT) does not have specific gear positions. In operation, it is similar to an automatic transmission, but the change in speed ratio differs from the gear-shifting process of an automatic transmission, resulting in continuous and smooth power delivery. Transmission Fluid Replacement: For the Toyota Corolla, manual transmission fluid is generally replaced every two years or 40,000 kilometers, while automatic transmission fluid is replaced every four years or 80,000 kilometers. CVT transmission fluid is typically maintenance-free, but it should be inspected at 80,000 kilometers and replaced as needed based on usage. Precautions: The temperature of the automatic transmission affects its lifespan. Temperatures exceeding 75 degrees Celsius can easily damage internal components, so using high-quality transmission fluid is crucial for protecting your vehicle.

Can Electric Vehicles Use Household Electricity for Slow Charging?

Electric vehicles can use household electricity for slow charging. Below are specific issues regarding household slow charging: 1. Charging Time: Charging an electric vehicle at home does not violate electricity regulations, but since household electricity is generally 220V, it can only support slow charging, often taking over 8 hours to fully charge. This makes it more suitable for overnight charging. Many electric vehicles now allow setting charging times, which is particularly beneficial in areas with peak and off-peak electricity rates. Users can plug in the charger and set it to start automatically during cheaper off-peak hours. 2. Electricity Rate Increase: Besides the limitation to slow charging, another major issue is that most households use tiered electricity pricing. Frequent EV charging can push the household into the highest pricing tier within 2-3 months, as EVs consume significantly more electricity than typical household appliances—often over ten kilowatt-hours per charge. Even at the highest tier, calculations show EV charging is still cheaper than fueling a gasoline car, though it raises the cost of other household electricity usage. 3. Charging Methods: Most electric vehicles can be charged at home, typically in two ways: low-voltage slow charging and high-voltage fast charging. Low-voltage slow charging uses standard 220V household electricity, is slower, and causes less battery wear, making it ideal for overnight charging. High-voltage fast charging requires industrial-grade high-voltage electricity and is available at pilot charging stations in major cities promoting EVs, similar to gas stations. For example, the BYD E6 can reach 80% charge in just 15 minutes with this method. While possible at home, fast charging requires a dedicated charging station resembling a large transformer.

What are the causes of Audi's automatic start-stop system malfunction?

Audi's automatic start-stop system malfunction causes: 1. Accidental pressing of the automatic start-stop button, resulting in system shutdown. Check whether the system is turned off; 2. The seat belt is not fastened or the left front door of the vehicle is not closed; 3. Line failure or other reasons lead to the failure of the start-stop system. It is necessary to go to the 4S store for maintenance as soon as possible. Audi is a German luxury car brand, and its logo is four interlocking rings. The headquarters is located in Ingolstadt, Germany. The main models include A1, A3, A4, A5, A6, A7, A8, Q1, Q2, Q3, Q5, Q7, Q8, TT, R8, and S and RS performance series.

Why is there no air coming out from the central air vent of the Corolla?

The reasons for no air coming out from the air conditioner are a clogged air filter or a damaged blower. Below are the relevant explanations regarding the air conditioner not blowing hot air: 1. Reasons for the air conditioner not blowing hot air: (1) When the air conditioner is heating in winter, there is a preheating stage after startup. The outdoor unit starts working first, and the indoor unit begins to blow air only after the temperature of the indoor pipes starts to rise. This is because the air conditioner has a cold air prevention function. (2) Another possibility is that during the initial period after startup, the outdoor unit may have frost buildup and needs defrosting. During this stage, the indoor unit does not operate. Defrosting usually takes about 10 minutes, and hot air will only be blown out after defrosting is completed. (3) If it is an issue with the air conditioner, it means the heating-related components are not functioning properly due to damage or malfunction. 2. Solutions for the air conditioner not blowing hot air: (1) If there is no hot air within the first 10 minutes after turning on the air conditioner, wait for a while and check again if air starts coming out. (2) Check if the fan wheel is stuck. If the fan wheel rotates freely, inspect the indoor temperature sensor and pipe temperature sensor, as the heating process involves a cold air discharge phase. (3) If there is an issue with the heating components of the air conditioner, it cannot be resolved by non-professionals. Therefore, it is necessary to call an air conditioner repair technician. Repairs are free during the warranty period, but if the warranty has expired, you will need to pay for the repairs yourself.

What causes the excessive oil temperature in a BMW 523?

Both poor heat dissipation from the oil cooler and excessive engine temperature can lead to excessively high oil temperature. The impact of the oil cooler on the oil: During warm-up, the oil cooler absorbs heat from the coolant, allowing the oil temperature to rise more quickly. When the temperature becomes too high, it is cooled by the coolant. This ensures the oil temperature remains stable and maintains an appropriate viscosity. The oil cooler not only cools the oil but also helps prevent oil degradation. Excessive engine temperature: This can cause increased wear between components due to thermal expansion, reducing the engine's lifespan. Additionally, high temperatures lower the oil viscosity, further exacerbating wear between engine parts. Therefore, special attention should be paid to engine temperature during hot summer months. The normal coolant temperature is around 90°C, while the normal oil temperature should be within the range of 95-105°C. A temperature of 110°C is considered slightly high. If the oil temperature is excessively high and the fan continues to operate for cooling after the engine is turned off, it is advisable to have the vehicle inspected.
