7-speed dry dual-clutch transmissions do require transmission fluid changes. Transmission fluid is a lubricant that maintains the cleanliness of the gear system, ensuring proper transmission operation and extending the lifespan of the drivetrain components. Most transmission fluids are compatible with automatic transmissions on the market. However, even with the same transmission model installed in different vehicle models, factors such as torque, weight, rotational speed, and structure can vary. Therefore, manufacturers specify their own dedicated transmission fluids. Dual-clutch transmissions, also known as direct-shift gearboxes, utilize dry dual-clutch mechanisms that transmit power through direct metal plate contact. This provides more immediate power delivery, with the metal plates pressed tightly together to increase the gear ratio, resulting in direct and noticeable performance improvements.

What to Do When Water Enters the Car Engine Block?

Should move the vehicle out of the deep water area to ensure that the engine intake will not inhale water again, and park in a safe place. Manually cut off the fuel supply system and ignition system, then use the motor to run the engine, allowing the water that has entered the engine to be discharged smoothly. After the inspection is completed, use compressed air to clean the electrical connection parts inside the engine compartment to prevent corrosion caused by water accumulation in the electrical connection areas. After cleaning, conduct a road test of the vehicle to ensure that there are no abnormal noises from the engine during driving. If there are obvious driving noises, check the engine bearings and rotating parts.

How to Remove Car Rain Guard Adhesive?

If the adhesive is on the car glass, you can first use a hot towel or a hair dryer to heat the adhesive and try to peel it off. If it cannot be peeled off by hand, use a relatively soft utility knife blade to avoid damaging the car glass. Pour nail polish remover or essential balm onto the adhesive of the rain guard, wait for about three to four minutes, and then wipe it off with a cloth. Spray tar remover or non-drying adhesive remover onto the adhesive, then scrape it off with a fingernail or a soft plastic scraper. First, remove as much of the residual adhesive as possible.

How to Remove Water from Car Seat Cushion Foam?

First, before the liquid has completely soaked in, use items like paper towels or cloth to quickly wipe away excess moisture. If the liquid hasn't soaked in too much, you can consider using a hairdryer to blow dry it after heating, and place desiccant on the seat surface. If it's summer, you may consider parking the car in the sun and covering the seat with black canvas. The absorbed heat will raise the seat temperature, speeding up moisture evaporation. If too much liquid has soaked in and DIY methods can't solve the problem, consider taking it to a repair shop to have the seat removed and repeat the above operations.
