Is More Gears in a Transmission Always Better?

[ZacharyAnn]

Transmission gears are indeed better when there are more of them. More gears in a transmission lead to higher transmission efficiency and smoother gear shifting. The functions of a transmission are: 1. Changing the transmission ratio to meet the traction requirements under different driving conditions; 2. Enabling reverse driving; 3. Interrupting power transmission to the drive wheels when the engine starts, idles, shifts gears, or needs to stop for power output. The maintenance methods for a transmission include: 1. Regularly changing the transmission fluid; 2. Frequently checking the fluid level; 3. Avoiding coasting in neutral; 4. Regularly cleaning the transmission; 5. Avoiding forced gear disengagement; 6. Reducing the time spent idling to warm up the car.

As a seasoned driver who has driven countless models, I don't believe more gears are a universal solution. While additional gears can indeed optimize fuel efficiency and keep the engine in its comfort zone—like saving fuel during highway cruising—too many gears can cause smoothness issues. Especially in congested urban environments, frequent gear shifts may feel jerky and detract from the driving experience. Take my 9-speed transmission car as an example: when poorly tuned, it can feel sluggish at low speeds, making it less comfortable than a 6-speed. More importantly, the more complex the structure, the higher the maintenance costs, with more parts and higher repair expenses. Balancing the number of gears is key—6 to 8 speeds usually offer the best compromise between performance and reliability. Too many gears are like flashy car features; their practicality may be overrated.

Driving my 5-year-old automatic transmission car, having more gears has its benefits but don't overdo it. More gears, like an 8-speed transmission, can more precisely match engine speed at different velocities, helping save fuel, especially on long trips. However, there are also downsides: the transmission becomes heavier, higher manufacturing costs lead to increased purchase prices and subsequent maintenance fees. A friend of mine switched to a 9-speed car and spent thousands on a single repair after encountering issues. In actual driving, too many gears can be inconvenient in stop-and-go city traffic, with frequent gear shifts causing discomfort. Relatedly, the number of gears isn't the deciding factor; driving habits and road conditions are more crucial. In mountainous areas with many slopes, fewer gears can make for simpler control. For most people, 6 speeds are sufficient—more just adds unnecessary burden.

I have researched automotive technology for many years, and more gears don't necessarily mean better. While it can improve fuel efficiency, allow the engine to operate optimally, and reduce emissions, the marginal benefits diminish. More gears, such as a 10-speed transmission, increase structural complexity and the risk of malfunctions. If not properly calibrated, the shifting logic can become chaotic, resulting in poor driving experience. For the average car owner, cost-effectiveness is key—6 to 8 speeds are sufficient, and pursuing more isn't essential. Other aspects, like electronic control optimization, are equally important.

Driving this manual transmission car for daily commuting, I don't think more gears are always better. While a 7-speed transmission may offer slightly better fuel efficiency and easier highway cruising, it becomes troublesome in daily driving, especially during traffic jams with frequent gear changes. Maintenance costs are also higher – my friend's car with more gears required deeper pockets for repairs. In terms of driving experience, smoothness depends on design, and too many gears can actually make the car jerky. What matters is matching the number of gears to the car – smaller cars often feel more agile with fewer gears. Overall, around 6 speeds seems most practical.

After driving multiple vehicles with different transmissions, I found that having more gears has both advantages and disadvantages—it's not always better to have more. The benefits are obvious: more gears allow the engine to operate within its optimal range, improving fuel efficiency and responsiveness. The drawbacks include a significant increase in transmission weight, higher costs, complex maintenance, and common issues like valve body sticking. From a driving perspective, having too many gears, such as a 9-speed, can lead to frequent shifting in the city, which is uncomfortable. For everyday cars, I recommend choosing a 6-8 speed transmission—it's reliable, hassle-free, and strikes the right balance. Too many gears can just be cumbersome.
