Reasons for Difficulty in Shifting Gears in Automatic Transmissions

Here are the reasons for difficulty in shifting gears in automatic transmissions: 1. Operational aspects: Incorrect operation by the driver, with speed and gear not matching. 2. Clutch aspects: Rust on the transmission input shaft, the clutch driven disc not moving properly, poor return, preventing the gear from engaging along the normal path, resulting in difficulty in shifting; clutch malfunction, causing insufficient clutch separation travel, leading to incomplete clutch separation and inability to engage gears. 3. Transmission aspects: Old transmission oil needing replacement; if not replaced in time, its lubrication effect will decrease, causing difficulty in shifting; new car transmission components not reaching optimal break-in condition, leading to difficulty in shifting; cold temperatures causing the viscosity of gear oil in the transmission to not reach optimal condition, reducing lubrication effect, thus resulting in difficulty in shifting.

Why Do License Plates Fall Off on Rainy Days?

The reason is that the license plate is only secured with two screws, and the lower part has limited load-bearing capacity. Here are the relevant explanations: 1. Depth of accumulated water: When passing through waterlogged roads, first check the depth of the water. If the splashes pushed up by the vehicle do not submerge the license plate, it is safe to proceed. 2. Drive at low speed: When driving through waterlogged sections, maintain a low speed and check if the license plate has fallen off after passing through. 3. Securing: It is best to use four screws for the front plate, and a bolt-and-nut fastening method is even better, as it can maximize the assurance that the license plate will not fall off when passing through waterlogged roads.

Does idling for 12 hours harm the car?

Idling for 12 hours does harm the car. Here are the relevant explanations: 1. Environmental pollution: During idling operation, due to incomplete combustion in the cylinders, the exhaust contains a large amount of harmful components such as hydrocarbons, carbon monoxide, and nitrogen oxides. These harmful components enter the atmosphere and pollute the ecological environment. 2. Prone to carbon deposits: During idling, the vortex of intake air is weak, and the fuel combustion is incomplete, making it easy to form carbon deposits. Additionally, when the coolant temperature drops below 60°C, the combustion products in the cylinders may undergo chemical reactions with water, forming acids that increase the corrosion level of the cylinders.

What is the maximum length of a truck that a B license can drive?

B license can drive trucks with a maximum length of 9.6 meters. Here are the relevant details: 1. Scoring cycle: The holder of a B2 driver's license must undergo an inspection at the traffic management department of the public security authority within 30 days after each scoring cycle. However, if there is no scoring record within a scoring cycle, the inspection for that cycle is exempted. If there is a scoring record within a scoring cycle, an inspection is required. The scoring cycle refers to the cumulative scoring cycle for road traffic safety violations, which is 12 months with a full score of 12 points, calculated from the date the motor vehicle driver's license is initially obtained. 2. Permitted vehicle types: The B2 driver's license allows driving C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled cars), and M (wheeled self-propelled machinery vehicles), which is the same as the B1 driver's license.

What Causes the Steering Wheel to Make Abnormal Noises When Turning?

Generally, abnormal noises when turning the steering wheel are caused by issues such as a faulty thrust bearing, universal joint failure, lack of power steering fluid, or insufficient lubrication in the steering column. Here is some additional information: 1. The dangers of turning the steering wheel to the limit: When the steering wheel is turned to its limit, a noticeable abnormal noise can be heard, which is emitted by the pressure relief valve. The greater the steering angle, the higher the pressure of the power steering fluid. When turned to the limit, the power steering pump operates under high pressure, which can then release and impact the oil seal of the reservoir and the rubber boot of the steering gear. Over time, this can lead to oil leakage in the pipes and aging of the rubber boot. In severe cases, oil leakage can cause damage to the power steering pump. Therefore, experienced drivers avoid turning the steering wheel to the limit to prolong the lifespan of the power steering pump. 2. Solutions: (1) Aging or excessive play in the steering tie rod end. Replace the steering tie rod end and perform a wheel alignment. (2) Leaking steering gear boot. Replace the boot or reapply grease. (3) Steering gear malfunction. This may be due to excessive gear clearance in the steering gear, requiring replacement of the steering gear. (4) Improper tension or aging of the power steering belt. Adjust the belt tension or replace the belt.

What to Do If Water Gets into Diesel? Can It Still Be Used?

Diesel contaminated with water cannot be used. Here are the relevant explanations: 1. Engine: Water in diesel can damage the engine. When the engine draws in air, it may carry some water into the intake tract, forming water vapor that mixes with gasoline and burns completely, which has minimal impact on the engine. However, if a small amount of water enters the engine and mixes with the oil, the oil quality deteriorates. Oil containing water increases wear on engine components, potentially leading to increased engine noise and vibration during future vehicle operation. 2. Precautions: If the engine starts and then shuts down again after a few seconds, and repeated attempts to start it fail, this situation is the most severe. Since water cannot be compressed, when water enters the cylinder while the engine is still operating at high speed, the inability to compress water during the power stroke can directly cause the valves and connecting rods to bend, the piston to seize, severe wear in the cylinder block, and the crankshaft to bend. It is recommended to replace the diesel fuel as soon as possible.
