What Causes the Transmission Failure in the Envision?

The following are common transmission-related failures in the Envision: 1. Common transmission failures: gear shifting hesitation or jerking, shaking during acceleration, abnormal noises, transmission oil leakage, delayed engagement, lack of reverse gear, inability to drive, warning light illumination, dashboard prompts for transmission maintenance, no acceleration when pressing the gas pedal, being stuck in 3rd gear, absence of 6th gear, and other similar issues. 2. Symptoms of failure: These symptoms are mostly caused by issues within the Envision's AT transmission. It is highly likely that the failure stems from problems with internal wear-prone components such as the buffer plate, valve body, solenoid valve, transmission control unit (TCU), oil pump, aluminum drum, one-way lock-up clutch, double-sided drum, or planetary gear set. These issues can often be resolved by repairing the mechanical components inside the Envision's AT transmission or servicing the transmission control unit.

Where is koko wheel hub produced?

koko wheel hubs are produced in the auto parts industry in Shenzhen, Guangdong Province. The following is an introduction about the wheel hub ET value: 1. Meaning: The ET value of a wheel hub refers to the deviation degree between the installation section of the wheel hub and the centerline of the wheel rim, referred to as the offset. The J value represents the shape and height of the wheel hub flange. 2. Introduction to ET value types: A zero-offset wheel hub means the fixed surface of the wheel hub mounting hole is located at the centerline of the wheel hub; A positive offset wheel hub indicates that the distance between the joint surface of the wheel rim and the center of the wheel rim is towards the outer side; A negative offset wheel hub means the distance between the joint surface of the wheel hub and the center of the wheel rim is towards the inner side.

Is it necessary to replace the catalytic converter with an original one?

If it is damaged, it needs to be replaced; if it is only clogged, replacement is not necessary. Additional information about the catalytic converter is as follows: 1. Function: It refers to the catalyst that converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. 2. Substrate: The substrate component of the catalytic converter is a porous ceramic material installed in a specially designed exhaust pipe. It is called a substrate because it does not participate in the catalytic reaction itself but is coated with a layer of precious metals such as platinum, rhodium, palladium, and rare earth coatings. It is the most important external purification device installed in the vehicle's exhaust system.

What does the three-way catalytic OBD mean?

OBD is the abbreviation of On-Board-Diagnostic in English, which is translated as "on-board diagnostic system" in Chinese. The following is the extended knowledge about OBD: 1. Principle: When high-temperature automobile exhaust passes through the purification device, the purifying agent in the three-way catalytic converter will enhance the activity of three gases, CO, hydrocarbons, and NOx, promoting them to undergo certain oxidation-reduction chemical reactions. Among them, CO is oxidized into colorless and non-toxic carbon dioxide gas at high temperatures; hydrocarbons are oxidized into water (H2O) and carbon dioxide at high temperatures; and NOx is reduced into nitrogen and oxygen. The three harmful gases are transformed into harmless gases, thereby purifying the automobile exhaust. The premise is that there is still oxygen available, and the air-fuel ratio must be reasonable. 2. Function: The three-way cleaning agent can simultaneously clean the engine's intake system, combustion system, and exhaust system. It powerfully, quickly, and efficiently removes the colloidal carbon deposits in the intake tract and combustion chamber, as well as the chemical complexes attached to the oxygen sensor and three-way catalytic converter. The removed colloidal carbon deposits and chemical complexes will be fully oxidized and burned into gases and discharged. This achieves the goal of treating exhaust, significantly reducing CO, HC, and NOx.

Why can't the sunroof of BMW 5 Series open?

It may be due to a sunroof circuit failure, damage to the sunroof drive motor, or foreign objects stuck in the sunroof track. Here is some related information about the sunroof: 1. Cause: Many sunroofs open by sliding along tracks, which have small gaps. When opening the sunroof, dust and sand from the road can enter these tracks. Over time, the accumulation of sand and mud can make it difficult to open the sunroof. 2. Maintenance: Regularly clean any foreign objects from the sunroof track gaps and apply lubricant to the tracks periodically. Due to frequent sliding and opening, the lubricant in the tracks will gradually decrease from friction. This increases the friction in the tracks, leading to greater resistance. Additionally, avoid opening the sunroof when driving on bumpy roads to prevent excessive shaking that could damage the sunroof track components.

What brand is koko wheel hub?

The brand of koko wheel hub is Koko. Below is an introduction about the ET value of wheel hubs: 1. Meaning: The ET value of a wheel hub refers to the offset between the mounting surface of the wheel hub and the centerline of the wheel rim, commonly known as the offset. The J value represents the shape and height of the wheel hub flange. 2. Introduction to ET value types: Zero offset wheel hubs indicate that the mounting hole fixing surface of the wheel hub is located at the centerline of the wheel hub; positive offset wheel hubs indicate that the distance between the mating surface of the wheel rim and the center of the wheel rim is towards the outer side; negative offset wheel hubs indicate that the distance between the mating surface of the wheel hub and the center of the wheel rim is towards the inner side.
