Reasons for the gasoline smell when the air conditioning is on in the car: 1. External engine exhaust leakage or foreign objects at the air intake: This causes unpleasant odors to enter through the air conditioning intake. This situation is easy to check—just open the hood at a repair shop to see it clearly. 2. The air conditioning filter is too dirty: Regular cleaning and inspection can completely prevent odors. 3. Mold growth in the air conditioning ducts and evaporator: This type of repair is more troublesome and costly. Below is an introduction to air conditioning maintenance: 1. Comprehensive air conditioning inspection: When using the air conditioning for the first time in summer, check the air conditioning system, such as inspecting the refrigerant through the reservoir, whether the air filter is too dirty, and if there are any foreign objects in the radiator. 2. Pay attention to air conditioning cleaning: The air filter should be replaced regularly to prevent moldy smells. Additionally, the condenser should be cleaned periodically, and the radiator should be removed for thorough cleaning.

Can a Manual Transmission Converted to Automatic Pass the Annual Inspection?

Converting a manual transmission to an automatic one will not pass the annual inspection. Changing a manual transmission to an automatic requires replacing the gearbox. If you convert a manual transmission to an automatic, you need to replace the gearbox and also modify part of the drivetrain, which will not pass the annual inspection, and the cost of doing so is also very high. Additional information: Automatic transmission cars are generally more convenient to drive, easier to operate, and less tiring in traffic jams. Common automatic transmissions include dual-clutch transmissions, CVT transmissions, and AT transmissions. Dual-clutch transmissions are currently the most popular, offering high transmission efficiency and fast gear shifting. AT transmissions are the most mature and widely used, also known as torque converter transmissions. CVT transmissions are often found in Japanese cars, and vehicles equipped with them are generally more fuel-efficient.
