How to Use the Plus (+) and Minus (-) Signs in Automatic Transmissions?

[McMax]

Automatic transmission plus (+) and minus (-) signs are used in the manual mode of the vehicle. The (+) direction increases the gear, while the (-) direction decreases the gear. Most automatic transmissions are equipped with a manual mode, which adds some driving fun and is very convenient to operate since there is no clutch pedal. Relevant information about automatic transmissions is as follows: 1. Automatic transmission, as the name implies, does not require the driver to manually shift gears. The vehicle will automatically select the appropriate gear based on the driving speed and traffic conditions. 2. Generally, there are six positions for gears in automatic transmission cars, from top to bottom: P, R, N, D, S, L.

I've been driving for many years. The plus and minus signs on an automatic transmission are essentially the manual mode's gear shifting operations. The plus sign is used to upshift, while the minus sign is used to downshift. When overtaking on the highway, I use the minus sign to downshift, which increases the engine RPM and gives the car more power to pass. Downshifting is also common when climbing hills or carrying heavy loads to avoid a feeling of powerlessness. Upshifting with the plus sign is suitable for steady-speed driving, such as in city traffic jams, making the engine quieter and more fuel-efficient. On long downhill slopes, switching to manual mode and using a lower gear helps with braking and reduces brake wear. This feature is easy to learn and beginner-friendly—just practice in an open area first and avoid random shifting. Proper use can enhance driving pleasure, but always pay attention to speed and avoid exceeding the limit—safety comes first. Once familiar, combine it with different road conditions to switch flexibly, making the car more responsive and extending the transmission's lifespan a bit.

I often play with the plus and minus modes when driving an automatic transmission car. Upshifting by pressing the plus sign increases the gear, lowers the RPM, and may result in higher speed, which is suitable for fuel-efficient driving like urban commuting. Downshifting by pressing the minus sign drops the gear, causing the RPM to surge and giving the car more power, ideal for sudden acceleration or climbing steep slopes. When I went out with friends on mountain roads and encountered steep slopes, I used the minus sign to maintain the car's power. It can also serve as auxiliary braking when going downhill, avoiding the danger of brake fade from constant braking. When first trying it out, practice in an empty parking lot without rushing. Once you get used to it, it becomes really convenient for handling complex road conditions with more stable manual control. Remember not to switch gears too frequently to avoid damaging the transmission, especially during prolonged downhill driving. Manual mode has its benefits, but it should be combined with the default automatic driving style for safe driving.

I find the manual shift buttons on automatic transmissions quite intuitive - the plus sign means upshift and the minus sign means downshift. In principle, it temporarily takes over transmission control to change gears, such as downshifting when overtaking to increase engine RPM for faster acceleration. Downshift when climbing to avoid power shortage, and use lower gears when descending for engine braking to protect the brake system. Beginners may make mistakes but can learn quickly by practicing timing on straight roads first. Upshift when engine RPM is too high to save fuel, or downshift when RPM is too low or more power is needed. I rarely use it except when necessary to avoid overuse that increases fuel consumption. Understanding the recommended usage in the vehicle manual enhances driving control and saves some maintenance costs.

I think the plus and minus manual mode in automatic transmissions is quite useful in specific scenarios. The plus sign for upshifting is used when the speed is stable, such as during highway cruising, making the engine quieter. The minus sign for downshifting is helpful on mountain roads or slippery surfaces in rain or snow, providing extra control—downshifting on descents aids braking, while it boosts acceleration for overtaking or climbing hills. I rely on this feature during my weekly long-distance drives to avoid brake fatigue, and it adds stability in rough terrain. When practicing, stay focused and watch the speed indicator. While I mostly use automatic mode, manual switching is straightforward and allows for quick reactions. Just remember not to force downshifts beyond the redline, as it can harm the transmission. Overall, the plus and minus functions are practical tools that enhance driving adaptability, with safety as the priority.

I mainly use the manual function of the automatic transmission with the plus sign for upshifting and the minus sign for downshifting to control driving. When overtaking or climbing steep slopes, pressing the minus sign to downshift makes the engine rev faster, providing a strong boost without struggling uphill. The plus sign for upshifting is used on smooth roads, like rural highways, when the speed is steady, lowering the engine RPM for better fuel efficiency. On long descents, manually shifting to lower gears by pressing the minus sign multiple times uses engine braking to reduce the burden on the brakes, making it safer and more reliable. At first, I made mistakes with the gears, but after practicing a few times, I got the hang of it—just avoid using it randomly in heavy traffic. Proper use can prevent engine idling, extend transmission lifespan, make daily commutes smoother, and boost driving confidence, but always prioritize safety and obey traffic rules.
