What is the DSL gear in an automatic transmission?
2 Answers
d gear is the drive gear, the transmission will automatically shift up and down according to the speed and load, and can shift up to the highest gear. s gear is generally only second gear, and L is first gear. The following is relevant information about automatic transmission: 1. Definition of automatic transmission: Automatic transmission refers to not needing to shift gears while driving, and its advantage over manual transmission is that it is easier to drive. 2. Gears of automatic transmission: Generally, there are six gear positions on an automatic transmission car, from top to bottom: P, R, N, D, S, L. Automatic transmissions include continuously variable transmission, electronic paddle shift, and electronic gear lever shift. There are three types of transmissions on the market: manual transmission, automatic transmission, and semi-automatic transmission.
I've been driving a taxi for fifteen years, and DSL gear is actually another name for low gear. When we're driving on mountain roads and encounter a long downhill slope, constantly pressing the brakes can make the brake pads smell burnt. At this point, shifting to DSL gear allows the engine to drag the speed, making it much safer. Nowadays, some new car models integrate this function into manual mode, but the principle is similar—locking in a low gear to increase engine RPM and using engine resistance to control speed. Last time I was driving on the Yun-Gui Expressway, a 20-kilometer-long downhill slope was handled entirely by this feature, not only saving the brakes but also making cornering more stable. If you're driving an automatic and encounter a steep slope or need engine braking, don't hesitate—just switch to this gear and you'll be fine.
