In an automatic transmission car, the +- is used for shifting gears up and down after switching to manual mode. To upshift, push the gear lever in the "+" direction, and to downshift, push it in the "-" direction. Below is some relevant information about automatic transmissions: 1. Introduction to automatic transmissions: As the name suggests, an automatic transmission does not require the driver to shift gears manually. The vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Generally, automatic transmission cars have six gear positions, from top to bottom: P, R, N, D, S, L. 2. Working principle: An automatic transmission uses planetary gear mechanisms to shift gears. It can automatically change gears based on the degree of throttle pedal pressure and changes in vehicle speed. The driver only needs to control the speed by operating the accelerator pedal.
