What gear should an automatic transmission car use when starting on a steep slope?
1 Answers
When starting on a steep slope with an automatic transmission car, use the D gear. The following is an introduction to automatic transmission cars: 1. Principle of automatic transmission cars: Since the torque converter's automatic transmission and torque conversion range is not wide enough, several rows of planetary gears are connected in series behind the turbine to improve efficiency. The hydraulic control system automatically operates the planetary gears according to the engine's working changes, thereby achieving automatic transmission and torque conversion. 2. Disadvantages of automatic transmission: The mechanism is complex and difficult to repair. The hydraulic oil circulating at high speed in the torque converter will generate high temperatures, so specified high-temperature-resistant hydraulic oil must be used.
