What does D/S± mean in automatic transmission?
3 Answers
D/S± in automatic transmission refers to the manual mode of an automatic gearbox. When the gear lever is pushed to the right in D/S mode, it enters manual mode. Pushing the lever forward towards "+" shifts up, while pulling it backward towards "−" shifts down. To protect the transmission in manual mode of a semi-automatic transmission, manual shifting is also restricted. When shifting up manually, the transmission will only upshift when the engine reaches the maximum speed matching the current gear. Conversely, when shifting down manually, the transmission will downshift only if the engine does not exceed the speed limit. A semi-automatic transmission not only has the function of automatic shifting but also simulates manual shifting. Its emergence allows more car models to break free from the constraints of traditional automatic transmissions, giving drivers the freedom and driving pleasure of manual shifting.
I've been driving automatic transmission cars for over twenty years. D/S± represents different driving modes: D stands for Drive, the normal gear where the car shifts gears automatically, making it worry-free and suitable for city commuting and smooth driving; S is Sport mode, which delays upshifting to keep the engine RPM high, providing strong acceleration and a thrilling experience when overtaking—perfect for mountain roads or when you want to push the car; ± is the manual shifting symbol, allowing you to use the paddle shifters to press + for upshifting or - for downshifting, giving you high flexibility in controlling the gears—like driving a manual but without the risk of stalling, ideal for winding roads or when precise power adjustment is needed. For daily driving, I recommend using D mode for fuel efficiency and safety. On highways, switch to S for fun. Newcomers to manual mode can get the hang of it with a bit of practice, but avoid frequently revving the engine too high to prevent damage. Remember to change the transmission fluid during maintenance to extend its lifespan. Driving requires flexible switching between these options based on road conditions, enhancing both driving pleasure and safety.
As a car enthusiast, the D/S± combo is just awesome: D for Drive is the basic automatic mode, smooth and effortless; S for Sport revs up the engine to unleash power, accelerating like a rocket for an exhilarating speed rush; ± manual paddles let you take control with upshift + and downshift -, dictating shift timing like a track racer. Normally, playing with S on highways boosts driving excitement, while manual mode offers precise power control in corners—just watch the RPM to avoid excessive wear. I love experiencing different modes: S for strong hill-climbing power on mountain trips, D for steady city driving. Practicing manual mode sharpens skills, but don’t overuse S to save fuel and engine health—regular transmission maintenance keeps performance durable.
