Causes of Automatic Transmission Shift Shock

There are many possible causes for harsh shifting in an automatic transmission. The main reasons include improper adjustment, degraded or damaged components, and faults in the electronic control system. Specific causes include: 1. High engine idle speed: Check the engine idle speed. For vehicles equipped with automatic transmissions, the standard idle speed is typically around 750r/min. If the idle speed is too high, it should be adjusted according to specifications. 2. Improper adjustment of throttle cable or throttle position sensor, leading to excessively high main circuit oil pressure: Inspect the adjustment of the throttle cable or throttle position sensor. If not within specifications, readjust accordingly. 3. Delayed upshifting: Check the vacuum hose of the vacuum-type throttle valve. Replace if cracked; reconnect if loose.

What Causes Body Shaking When Speed Reaches 100?

Here are the reasons for body shaking: 1. If the steering wheel shakes, it indicates a problem with the front wheel balance; if the body shakes, it indicates a problem with the rear wheel balance. 2. Loose fasteners in various parts of the chassis causing mechanical resonance. 3. Severe engine carbon buildup might be the cause. Here are the solutions for body shaking: 1. Perform a four-wheel alignment and balance check. 2. It could be an issue with the ignition system; inspect the condition of the spark plugs, high-voltage wires, and ignition coils. 3. Replacing the wheel rims may be necessary to completely resolve the issue.

What are the situations that cause a manual transmission car to stall?

Here are the situations that can cause a manual transmission car to stall: 1. When starting the car, if the engine speed is insufficient and the clutch pedal is released too quickly, the engine will drive the transmission to turn the wheels. The idle speed of the engine suddenly encounters resistance, and because the speed and torque are insufficient, the engine is prone to stalling. 2. When braking, if the car's speed decreases but remains in a high gear, the engine may not be able to handle the load due to insufficient speed, leading to stalling. 3. Sometimes, beginners may experience the car rolling back when starting, which can cause panic and lead to stalling. In this case, it's important to use the handbrake properly. Before starting in gear, pull the handbrake tight, then lift the clutch halfway, release the handbrake, and apply the throttle. This method prevents the car from rolling back and avoids stalling.

Does driving through during a yellow light count as running a red light?

According to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," when the yellow light is flashing at an intersection, vehicles that have already crossed the stop line may continue to proceed. Therefore, crossing the stop line during a yellow light does not count as running a red light. If the yellow light is already on and a vehicle continues to force its way through, it will be considered running a red light if captured by cameras. If the yellow light is already on and a vehicle continues to force its way through, it will be considered running a red light if captured by cameras. According to the relevant provisions in the "Procedures for Handling Road Traffic Safety Violations," motor vehicle drivers who violate traffic signal lights at intersections will be penalized with 6 demerit points. Additionally, according to the relevant provisions in the "Road Traffic Safety Law," fines may also be imposed. Criteria for determining running a red light: Electronic cameras capture three photos as evidence for determining a red light violation: the front wheels crossing the stop line, the rear wheels crossing the stop line, and the front wheels crossing the opposite stop line. Only when all three photos are available will it be considered running a red light. According to Article 11 of the "Procedures for Handling Road Traffic Safety Violations," if a vehicle crosses the stop line when the red light is on but stops immediately, even if it has crossed the line, it will not be considered running a red light. However, it will be considered as stopping beyond the line, which, according to traffic laws, is classified as driving or stopping improperly at intersections, resulting in a 3-point penalty. How to avoid running a red light while driving: When there are arrow signal lights, follow the arrow lights; otherwise, follow the circular lights. When the red light is on, the front of the vehicle must not cross the stop line. When the yellow light is on, the front of the vehicle must not cross the stop line. When the green light just starts flashing, if the distance is close and the speed is high, the vehicle should proceed, as stopping might not be possible without crossing the stop line. If the distance is far, the speed is slow, or the intersection is congested, the vehicle should stop. When driving in the city, develop the habit of looking for traffic lights whenever encountering a crosswalk or stop line at an intersection.

What brand of antifreeze is used for the Buick Excelle?

The original antifreeze used in the Buick Excelle is DEX-COOL. Antifreeze is a coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year. Can different antifreeze brands be mixed? It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them could lead to chemical reactions between the additives, rendering them ineffective. How to determine if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it may indicate low antifreeze levels, though it could also be due to excessively high cylinder temperatures. Check the antifreeze reservoir. If the liquid level is below the minimum mark (MIN), do not continue driving and add antifreeze promptly. Check the water level scale on the antifreeze bottle. The normal antifreeze level should be between the maximum and minimum marks. If the antifreeze is below the minimum mark, it indicates a deficiency.
