Does a CVT Have Gears?

[DeHenry]

CVT transmissions do not have gears. Below is a detailed introduction to the advantages and disadvantages of CVT transmissions: 1. Advantages: The advantages of CVT transmissions include their compact size, simple structure, easy maintenance, and smooth operation. They are primarily used in Japanese, Korean, and some domestic vehicles. CVT transmissions allow the engine to consistently operate within an optimal RPM range, making vehicles equipped with this type of transmission generally more fuel-efficient. 2. Disadvantages: The disadvantages of CVT transmissions are their limited torque capacity and susceptibility to slippage. As a result, CVT transmissions are typically paired only with small-displacement engines. Larger-displacement engines produce higher torque and are better suited for AT transmissions.

When driving a CVT-equipped vehicle, I can clearly feel the absence of the gear-shifting jerks typical of traditional transmissions. In principle, CVTs rely on two conical pulleys and a steel belt to achieve seamless ratio changes, eliminating the need for physical gear settings. However, some automakers have added paddle shifters or manual modes to the steering wheel—these are essentially simulated shift sensations created through programming, as the steel belt continues to slide continuously. These simulated gears act more like a psychological comfort for those seeking a sportier driving feel, while the actual transmission control unit still automatically adjusts for the optimal ratio. This is precisely why CVTs are noticeably more fuel-efficient on long drives, as the engine consistently operates within its most efficient RPM range.

From a mechanical perspective, CVT transmissions indeed don't require fixed gears. I've compared the gear set structure of traditional AT transmissions using repair manuals - CVTs replace those complex gears with two hydraulic cone pulleys clamping a steel belt, with the gear ratio constantly changing. That's why you don't see gear indicators on new car dashboards, delivering smoothness like an electric vehicle. However, automakers later introduced a compromise: in sport mode or when using paddle shifters, the system deliberately pauses for fractions of a second at specific gear ratio intervals to simulate 6-speed or 7-speed shifting sensations. Ironically, these simulated gears actually worsen fuel efficiency, so it's more practical to switch back to D mode for daily driving.

I've repaired hundreds of CVT transmissions and can responsibly tell you there's no traditional gear structure inside. Those who claim there are gears are mostly misled by the +/- symbols on the shift lever or paddle shifters. When you actually open the casing during repairs, you'll only see the cone pulleys, steel belt, and oil pump assembly. The simulated gear function is just a software trick, similar to adding vinyl record sound effects to an MP3 player. Although there are no physical gears, be aware that wear on the cone pulley grooves can reduce transmission efficiency. It's recommended to change the dedicated transmission fluid every 60,000 kilometers to protect the cone pulley surface coating.
