What Causes the Jerking When Shifting from 2nd to 3rd Gear in a 6AT Transmission?

6at transmission 2nd to 3rd gear jerking reasons include stubborn dirt and impurities inside the transmission and solenoid valve damage. Dirt and impurities in the transmission: Automatic transmission jerking often occurs not due to internal valve body damage, but because of stubborn dirt and impurities inside, especially when these accumulate in the valve body, forming blockages that prevent effective regulation of oil pressure, leading to jerking, impact, and slippage. Remove stubborn dirt and impurities from the transmission. High temperature: High temperatures can degrade the quality and frictional properties of automatic transmission fluid, increasing friction and wear, which leads to transmission noise. At the same time, sludge, impurities, or dirt can form inside the transmission, causing jerking and impact. If the temperature exceeds 120 degrees Celsius, rubber sealing materials begin to harden, eventually leading to leaks and reduced hydraulic pressure. If the temperature rises further, the transmission may start to slip, and slipping in turn causes the temperature to rise even higher. If not addressed promptly, the transmission may fail completely.

Is It Necessary to Apply a Film to the Car's Front Windshield?

Applying a film to the car's front windshield is optional and depends on individual needs. Advantages: The front windshield has a large heat-absorbing area and is exposed to the most UV radiation. Applying a film can effectively block UV rays, protecting the health of the driver and passengers. It can also reduce some heat and effectively diminish blinding glare. Since the front windshield is made of tempered safety glass, if the glass shatters, a pre-applied film can prevent fragments from scattering, thereby enhancing the driver's safety. Disadvantages: Applying a darker film may not only impair the driver's visibility at times but also cause reflections on the car body, affecting the visibility of drivers behind and potentially increasing the risk of rear-end collisions. Additionally, metal films can interfere with ETC and GPS signals and may cause issues like high reflectivity.

Can I Drive at 80 mph After Applying a Car Cover?

You can drive at 80 mph after applying a car cover. Car Cover: A car cover, also known as the "clothing" for cars, is a protective accessory made of durable and wear-resistant materials like canvas, tailored to the exact dimensions of the vehicle. The advantage of a custom-made cover is that it fits the car perfectly, providing excellent protection against dust, rain, and other elements, thus preserving the car's appearance. Using a car cover helps maintain the car's paint in pristine condition for the next use. It is convenient to use: first, cover the side mirrors, then stretch the cover over the front and rear of the car, and finally tighten the straps to secure it. The car cover consists of three parts: the main body, straps, and spring hooks. The front strap is closed and is put on over the front of the car, while the rear strap is open and secured with a lock at the rear, which cannot be removed without a special key. The spring hooks on both sides of the cover attach to the lower edges of the car body to keep it firmly in place. Functions of a Car Cover: It effectively prevents harmful dust from entering the cabin and engine compartment, protects the interior from aging and the engine from wear due to sun exposure, and shields the car's surface from the damaging effects of acidic rain and snow in polluted urban environments. In summer, a car cover can effectively prevent excessive interior temperatures and protect the interior materials from heat-induced aging. When the car is not in use for a period, the cover ensures it remains as shiny as new. It also offers protection against UV rays, acid rain, intense sunlight, paint fading, discoloration, and drying or cracking of interior leather and decorations, as well as preventing scratches from sharp objects. Using a car cover reduces the need for frequent washing, helping to maintain the paint's gloss.

How much can you exceed the speed limit during interval speed measurement?

Interval speed measurement does not allow exceeding the prescribed speed by more than 10%. Penalties for interval speed measurement: If the speed exceeds the limit by less than 10%, a warning will be issued. On roads with a speed limit below 50 km/h, exceeding the limit by 10% to less than 20% will result in a fine. Exceeding the limit by 20% to less than 50% will result in a fine; exceeding by 50% to less than 70% will result in a fine; exceeding by 70% or more will result in a fine. On roads with a speed limit between 50 km/h and 80 km/h, exceeding the limit by 10% to less than 20% will result in a fine. Exceeding the limit by 20% to less than 50% will result in a fine; exceeding by 50% to less than 70% will result in a fine; exceeding by 70% or more will result in a fine. On roads with a speed limit between 80 km/h and 100 km/h, exceeding the limit by 10% to less than 20% will result in a fine. Exceeding the limit by 20% to less than 50% will result in a fine; exceeding by 50% to less than 70% will result in a fine; exceeding by 70% or more will result in a fine. Interval speed measurement: A method to measure the average speed of a vehicle passing through a section between two adjacent speed monitoring points (speed interval). For example, if the speed interval of a highway section is 10 kilometers with a speed limit of 120 km/h, a vehicle that takes 5 minutes or more to complete the section has an average speed below 120 km/h, meeting the speed limit requirement. If the vehicle takes less than 5 minutes to pass the interval, it is speeding.

Method for Adjusting the Dongfanghong Clutch

For the Dongfanghong clutch, first adjust the clearance between the brake pressure plate and the brake disc, then adjust the pedal free travel. Clutch Slipping: Symptoms include slow starting in low gear, difficulty starting in high gear, and occasional shaking; reduced tractor traction; when the load increases, the vehicle speed fluctuates or even stops, but the internal combustion engine sound remains unchanged; in severe cases, the clutch overheats, the friction plate smokes, and there is a burnt smell. Causes and Solutions: Oil contamination on the friction plate surface. This is mainly caused by damaged oil seals or other sealing devices leaking lubricating oil, or improper maintenance with excessive oil injection. Identify the source of the contamination, eliminate it, and then clean the clutch. Insufficient or no free clearance in the clutch. Readjust the clearance. Broken or weakened pressure springs. Replace the springs. Worn friction plate. If the friction plate is unevenly worn, severely burnt, or too thin with exposed rivet heads, replace it; if the wear is minimal and the rivet heads are buried at least 0.5 mm deep, replacement may not be necessary. However, if the rivets are loose, re-rivet or replace them with new rivets. If the friction plate is slightly burnt, smooth it with sandpaper. Warped driven disc or excessive unevenness of the flywheel and pressure plate surfaces should be corrected and repaired. Loose or broken return springs should be replaced.

What to Do When the Vehicle Fails to Start and Makes Abnormal Noises?

When the vehicle fails to start and makes abnormal noises, it is the sound of the starter motor turning the engine. Engine fails to start: Insufficient battery voltage: When the battery power is inadequate, it cannot drive the engine to reach the starting speed, preventing the vehicle from starting. The repeated engagement of the magnetic switch and starter relay produces abnormal noises, which are relatively small and occur once per starting attempt. Abnormal noises: Excessive carbon buildup in the intake manifold: Excessive carbon deposits on the throttle body, idle air control valve, etc., prevent the engine's air-fuel mixture from reaching the required ratio, causing the vehicle to fail to start. The engine continuously attempts to start, resulting in abnormal noises. Insufficient fuel supply in the fuel system: This phenomenon is essentially similar to excessive carbon buildup in the intake manifold, also preventing the engine from achieving the required air-fuel mixture ratio. As a result, the engine continuously attempts to start, producing abnormal noises. Ignition system failure: This directly prevents the engine from starting, and the engine continuously attempts to start, generating abnormal noises.
