Transmission fluid must be changed, and the consequences of not changing it are: 1. The transmission fluid will become thicker, blocking the transmission cooler; 2. It will cause the fluid to deteriorate and reduce viscosity, leading to larger particles or debris that can clog the oil passages; 3. It will accelerate the wear of mechanical components, damaging the automatic transmission planetary gear set and differential; 4. It will corrode the gears inside the transmission. The method for changing transmission fluid is: 1. Remove the transmission guard plate, loosen the screws on the oil pan, and drain the old transmission fluid; 2. Unscrew the screws on the oil pan and remove the oil pan; 3. Apply sealant to the new oil pan and tighten it; 4. Loosen the screw on the left side of the transmission to add new fluid.

Should the right turn signal be used for parallel parking?

No, there are only three situations in Subject 2 where the turn signal is required: starting; when exiting during parallel parking; and when starting on the slope during the slope fixed-point parking. In all these cases, the left turn signal is used. Below is relevant information: Introduction: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and refers to the field driving skills test. Test content: For the C1 license, the test items include reversing into a parking space, parallel parking, slope fixed-point parking and starting, right-angle turns, and curve driving (commonly known as S-curves) as the five mandatory items (some regions include a sixth item, high-speed card collection). For the C2 license, the test items include reversing into a parking space, parallel parking, right-angle turns, and curve driving (commonly known as S-curves) as the four mandatory items.

What causes the car to pull to the right when the steering wheel is released?

The reasons why the car pulls to the right when the steering wheel is released are: 1. Excessive wear on the right-side tires; 2. Damage to the ball joint or shock absorber; 3. Uneven tire pressure on both sides of the vehicle; 4. Deformation or poor performance of related components in the vehicle's suspension system; 5. Issues with the vehicle's four-wheel alignment. The methods to address car pulling are: 1. Hold the steering wheel firmly with both hands to control the vehicle as much as possible, and gently tap or lightly apply the brakes without locking them; 2. Try to drive the car to the side of the road and control the speed; 3. Turn on the hazard lights or set up a warning triangle; 4. Perform a four-wheel dynamic balance. The impacts of steering wheel misalignment are: 1. Severe tire wear, accelerating their time to scrap; 2. Risk of tire blowout, leading to loss of vehicle control.
