Because of being in a big city, traffic jams are always inevitable. I think driving skills are not top-notch, so when choosing a car, the main consideration is automatic transmission. At the same time, the current auto market is not very prosperous, and car prices have fallen again and again, which has also enriched my choice of models. After driving the automatic transmission for a while, I found some problems, that is, when I use the L gear to drive, a mushy smell will be produced for a longer time. During this process, I did not perform rapid acceleration or rapid deceleration. Why did this phenomenon occur? Isn't it the smell of the clutch? Isn't this possible only with manual transmission cars?
Diagnosis and treatment opinions:
This is why this situation occurs, and it has a lot to do with your use. According to the practice of using automatic gears, the L gear is generally only used under rain or snow conditions and when the road adhesion is low, it will improve When the engine is turned and the gear is driving, the speed of the vehicle will rise quickly due to the good road conditions. At this time, the transmission will not perform gear shifting due to the limitation. This will increase the engine speed and generate huge heat. It will produce a vague taste if it reaches the interior decoration of the vehicle or the three-way catalytic device. Therefore, in the case of good road conditions, you should avoid driving in L gear. On the one hand, it is beneficial to increase the speed and reduce fuel consumption. On the other hand, it can protect your car's engine and transmission from damage.
