How to Shift an AT Transmission?
2 Answers
AT transmission shifts through planetary gear mechanisms, automatically adjusting speed based on throttle pedal position and vehicle speed changes. The driver controls the vehicle's speed by operating the accelerator pedal. Transmission types include hydraulic automatic transmissions, hydrostatic automatic transmissions, electric automatic transmissions, stepped mechanical automatic transmissions, and continuously variable mechanical automatic transmissions. Also known as gearboxes, transmissions consist of gear transmission mechanisms and control mechanisms. They are automotive components used to alter the engine's rotational speed and torque, capable of fixing or changing the output/input shaft transmission ratio in distinct gear steps.
I've been driving automatic transmission cars for almost ten years, and shifting gears is actually quite intuitive. Before getting in the car, check the PRND on the gear lever. To start the engine, you must press the brake and have the gear in P; reverse by shifting to R, and switch to D when moving forward. Once on the move, you don’t need to worry at all—the transmission shifts gears automatically based on speed. When parking, firmly press the brake, shift to N first, engage the handbrake, and then switch to P, especially on slopes, to avoid excessive stress on the transmission that could damage its internals. While driving, apart from shifting to D, never randomly move the gear lever—like switching to P or R at high speeds, which can cause serious malfunctions. Some cars have an S gear for sport mode or manual shifting, which I occasionally use on mountain roads. But for daily driving, 99% of the time, I just use D—it’s worry-free and safe. Oh, and don’t forget to regularly maintain the transmission fluid.
