What Do PRNDM Stand for in Terms of Gear Positions?

[Holly]

P stands for Park; R stands for Reverse; N is commonly known as Neutral in manual transmission vehicles; D stands for Drive; M stands for Manual mode. Engaging P gear when parking can prevent the car from rolling; R gear should be engaged when the car needs to reverse; N gear in automatic transmission vehicles can be used during brief stops; engaging D gear allows the car to move forward; after entering M gear, the transmission will not automatically shift up. P gear is the parking gear in an automatic transmission, the most common gear position in automatic transmission vehicles, usually located at the foremost position on the gear console, primarily to lock the axle when the car is stationary on a slope. R gear is the reverse gear, one of the three standard gear positions in a car, marked as R on the gear console, mainly enabling the car to move backward, a special driving gear. The reverse gear is present in all cars, usually marked with a capital R. Engaging reverse gear makes the car move in the opposite direction to Drive, allowing the car to reverse. N gear is Neutral, where the transmission lever is not engaged in any forward or reverse gear, completely separating the transmission from the drive wheels. In manual transmissions, Neutral is in the middle position, while in automatic transmissions, it is marked as "N". Coasting in Neutral is commonly believed by drivers to save fuel, especially among truck drivers who often turn off the engine and coast in Neutral to conserve fuel. D gear is Drive, also known as the driving gear. In this position, the transmission automatically shifts between 1 and overdrive (equivalent to 1-4 gears) based on speed and throttle conditions, used for normal road driving. Due to different designs in various countries, "D" gear generally includes gears from 1 to high gear or 2 to high gear, automatically shifting based on speed and load changes. M gear is Manual mode, where the transmission does not automatically shift up after entering this position. M+ is the upshift in the manual mode of a semi-automatic transmission, while M- is the downshift in the manual mode of a semi-automatic transmission.
