How many shift modes does the transmission have?

Gear shifting of automobile gearbox refers to the operation process that the driver constantly changes the position of gear lever with the change of road surface and speed through various psychological and physiological movements. In the long-term driving process, its name has been circulated by people because of its simplicity and directness. It is used frequently. Moreover, the proficiency of operation (especially manual transmission cars) directly affects people's driving safety. There are the following transmission shift modes: 1, pocket shift: the pocket shift lever is placed in the installation position of the wiper lever of most vehicles in China, and its appearance is very similar. The gear lever of a car is placed under the steering wheel. Because the gear lever is pushed into the arms when shifting gears, it is vividly called "Huaidang". The working principle of gear shifting is the same as that of ordinary automatic transmission. When the vehicle speed is lower than 1 1 km, the D, N and R gears can be switched freely. When the vehicle speed exceeds 1 1 km, the gear will be locked. 2, knob shift: knob shift is actually a kind of electronic shift lever. As the name implies, the knob shift is achieved by controlling the knob. When you put in which gear, the indicator light will light up. When the engine is turned off, the knob will form a plane with the center console downward, and it will rise again after starting the engine, which looks very delicate. 3. Push-button gear shifting: Push-button gear shifting changes gears into electronic buttons, which are exquisitely arranged on the center console. When operating, you need to step on the brakes and ignite. Just like other automatic transmissions, you just need to get used to the position of shifting gears and the operation of keys. Push-button shifting can only be achieved by shifting paddles, so now Lincoln models basically provide steering wheel shifting paddles. 4, knob shift: knob shift is based on the original manual gearbox, mainly changing the manual shift control part. That is to say, without changing the manual gear shifting structure, an automatic control system controlled by a microcomputer is added to realize the automation of gear shifting. In fact, it is a manual gear that does not need to step on the clutch. In addition to using the knob to shift gears, it is also equipped with a shift paddle.
