Solutions for water ingress in dry dual-clutch transmissions: 1. Clean water ingress: Avoid driving and running the engine as much as possible. In this case, the water will settle at the bottom of the gear oil in the transmission. Open the drain screw at the bottom of the transmission to release all the water and oil, then refill with new gear oil. 2. Dirty water or water with sediment ingress: The transmission needs to be removed and opened for cleaning. If sediment enters the bearings, especially the input shaft bearing, all components inside the transmission must be disassembled and cleaned. Below is an introduction to related content: Difference between dry and wet types: The torque transmission of a wet dual-clutch is achieved through friction plates immersed in oil, while the dry type transmits torque through friction plates on the clutch driven disc.

Is Warranty Voided Without Maintenance at 4S Stores?

Maintenance outside 4S stores does not void the warranty, as warranty coverage is not exclusively tied to 4S store services. However, if the vehicle is still under warranty, it is advisable to opt for maintenance at a 4S store. The automobile three-guarantee policy stipulates that during the warranty period, consumers must have their vehicles serviced at manufacturer-authorized 4S stores to be eligible for the three-guarantee benefits. The car warranty period refers to the timeframe during which the manufacturer provides free repairs and maintenance for faults arising from quality issues. There are two conditions for warranty coverage: a time limit of 2 years and a mileage limit of 60,000 kilometers.

Can Automatic Transmission Cars Stall?

Automatic transmission cars can stall. Whether a car stalls is unrelated to whether it's automatic or manual transmission. Stalling occurs due to faults in the engine's fuel system or electrical system - sudden stalling is caused by electrical issues, while gradual stalling is due to fuel system problems. Automatic transmission typically refers to a car's automatic gear-shifting mechanism, where the control system of the automatic transmission automatically selects the appropriate gear based on engine speed and load during driving, replacing the driver's subjective judgment of timing and gear-shifting operations. Introduction to the gears in automatic transmission cars: 1. P stands for Parking gear, used when parking; 2. R stands for Reverse gear, used when reversing; 3. N stands for Neutral gear, used when starting the engine; 4. D stands for Drive gear, used when the car is moving forward; 5. L stands for Low gear, mostly used for climbing or descending hills; 6. S is equivalent to 2nd gear, only shifting between 1st and 2nd gears.
