Transmission fluid needs to be replaced. Here is the relevant information about transmission fluid replacement: 1. Dry dual-clutch transmissions and manual transmissions have similar structures, so they both use synthetic transmission fluid with a service life of approximately 150,000 kilometers. Most automatic transmissions require fluid replacement every 60,000 to 80,000 kilometers. 2. The transmission fluid replacement cycle is just a general guideline. Due to factors such as driving conditions and habits, the condition of the transmission fluid may vary. If the vehicle experiences issues like rough shifting, strong jerking sensations, or significantly increased noise during use, it is necessary to check whether the transmission fluid needs replacement. 3. There are three common methods for replacing transmission fluid in vehicles: (1) Gravity drain: Similar to changing engine oil, the transmission fluid drain bolt is loosened to drain the fluid, and then new fluid is added through the fill port. The drawback is that gravity draining does not completely remove all the old fluid. (2) Machine flush: A transmission flush machine is connected to the transmission's fluid lines, and new fluid is added to the machine. The new fluid is then used to "push" out the old fluid from the transmission. The advantage is a thorough replacement, but the process is time-consuming and requires more transmission fluid. (3) Removing the transmission pan: The advantage is that the transmission filter can be cleaned or replaced directly, and the replacement is more thorough. The downside is that the procedure is more complicated.

Why does an automatic transmission always start in 2nd gear?

Automatic transmission always starting in 2nd gear is caused by a faulty transmission separator. Here is an introduction about the transmission: Introduction: The transmission, also known as a gearbox, is an automotive component used to alter the speed and torque from the engine, and can fixedly or stepwise change the transmission ratio between the output and input shafts. Function: It can be categorized into stepped, continuously variable, and integrated transmissions, with functions such as enabling reverse driving, interrupting power transmission, and changing gear ratios. Principle: Manual transmissions mainly consist of gears and shafts, achieving speed and torque variation through different gear combinations; while automatic transmissions (AT) are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variation through hydraulic transmission and gear combinations.

Is It Dangerous to Drive on the Highway After a Tire Repair?

Driving on the highway after a tire repair can be dangerous. Here is an introduction to tire repair: Introduction: The principle of car tire repair is to use glue for vulcanization (the bonding of rubber relies on vulcanization, including the combination of the tire tread and the tire body), so that the repair patch and the tire rubber layer fuse together to compensate for the hole. Usage: Cold repair glue can bond the patch and the tire without heating, so when repairing the tire, more glue is not necessarily better—just the right amount is sufficient. Hot repair is necessary because non-cold repair glue is used, and heating is required during the repair process to promote vulcanization, which is done using an electric iron-like device for heating.

What are the reasons for a diesel engine emitting black smoke and automatically shutting down?

The reasons for a diesel engine emitting black smoke and automatically shutting down are as follows: Poor diesel quality: The diesel used does not meet the standard performance requirements, leading to poor fuel combustion and black smoke. Blocked air intake: A blocked air intake cannot provide sufficient air during diesel combustion, resulting in incomplete combustion and black smoke from the diesel engine. Insufficient compression: Insufficient compression means the required pressure does not meet combustion requirements, worsening combustion conditions and causing black smoke. Changes in combustion environment: Long-term use of the diesel engine and other factors can alter the shape and volume of the combustion chamber, further reducing the quality of the fuel-air mixture, preventing the formation of a good mixture and worsening combustion conditions, leading to black smoke.

What does the 200km vehicle condition inspection mean?

Vehicle condition inspection at 200km means the car needs maintenance after driving 200km. The following is relevant information about car maintenance: Minor maintenance: Minor maintenance includes engine oil and oil filter, air filter, cabin air filter, wheel alignment, and tire pressure monitoring. During minor maintenance, note: When changing the engine oil, ensure to extract all the old oil before adding new oil. Major maintenance: Generally, a major maintenance is required every 40,000 to 50,000 kilometers. In addition to changing the engine oil and three filters, major maintenance also includes replacing brake fluid, transmission fluid, timing belt, cleaning the engine throttle body and fuel injectors, cleaning the fuel system, replacing spark plugs, inspecting the ignition system (including ignition coils), and finally checking if the tires need replacement and cleaning carbon deposits.
