Why Doesn't the Automatic Transmission Display the Real-Time Gear Position?

If the gear position is not displayed, first check whether the gear is normal and whether the driving is normal. If everything is normal, then the instrument panel may be faulty and needs to be checked at a 4S shop. Introduction to Automatic Transmission: Automatic transmission usually refers to the automatic gear shifting mechanism of a car. When driving, the control system of the automatic transmission automatically selects the appropriate gear according to the engine speed and load, thus replacing the driver's subjective judgment of timing and gear shifting operation. Automatic Transmission Gear Categories: P, R, N, D, S, L. The most commonly used automatic gears are parking gear P, reverse gear R, neutral gear N, and drive gear D. Principle of Automatic Transmission: The automatic transmission uses planetary gear mechanism for shifting, which can automatically shift gears according to the degree of the accelerator pedal and the change of vehicle speed.
As a veteran driver with over 20 years of experience, I really don't think automatic transmissions need to display gear positions since the car handles gear shifts automatically. The key is for drivers to focus on the road. Every time I start or go uphill, the car automatically shifts gears based on throttle pressure and speed, requiring no attention from me. In the manual transmission era, I had to watch the gear display to operate, but now with advanced technology, automatic transmissions simplify the interface by removing this distraction, making driving safer. Some luxury cars might display gears, but that's an unnecessary feature that increases costs and power consumption. Remember, reducing dashboard information interference while driving naturally lowers accident rates—that's design wisdom. Anyway, I'm used to focusing ahead and letting the computer handle gears—it's worry-free and effortless, ensuring my family's safe travels.
I've been into cars for years and understand the mechanism of automatic transmissions. The reason they don't display real-time gear positions is mainly to simplify design and reduce costs. Modern transmissions rely on electronic control units that calculate shift points hundreds of times per second - it's actually better that drivers can't see this process as it prevents unnecessary anxiety. Think about it: manual transmissions must display gears because drivers manually control them, but automatics are in 'idiot-proof' mode. Adding real-time display would increase sensor and screen costs, which doesn't make economic sense for small-displacement or budget models. I've personally tried modifying a car to add this display function and found it puts heavy load on the battery while being prone to errors - the gains don't outweigh the losses. Nowadays, driving focus has shifted to navigation and assist systems - gear position information has become outdated. Fewer displays mean cheaper car prices, and practicality comes first.
