CVT transmission is today’s most modern automatic transmission in the automotive industry.
Honda Accord CVT transmission is no stranger to many Honda drivers, with the outstanding features it brings to your journey.
So, What is the Honda CVT transmission? How is it structured and working? Does Honda have a CVT transmission? All will be revealed in the article below.
Overview of CVT Transmission
CVT stands for Continuously Variable Transmission, a type of transmission providing infinite gear ratios.
This automatic transmission helps vehicles achieve exceptional fuel economy efficiency while maintaining smooth and seamless operation.
CVT transmissions are increasingly featured in new car models, ranging from small cars to more high-end vehicles.
Prominent automotive brands, notably Honda, have adopted CVT in many vehicle offerings.
A CVT transmission honda accord operates by continuously varying the transmission ratio without distinct gears.
Instead of using gears like traditional transmissions, it utilizes a system of belts and two pulley sets (secondary pulley and primary pulley).
A V-belt or a timing belt connects these pulleys. The belt’s position on the pulleys can be adjusted to change the effective diameter of the pulleys, thereby altering the gear ratio.
The CVT can provide suitable gear ratios corresponding to the engine’s rotational speed by varying the gear ratio.
A CVT transmission continuously changes the gear ratio without fixed gears. It achieves this through the use of belts and two pulley sets.
The adjustable pulleys enable the transmission to create different gear ratios, allowing the engine to operate efficiently at various speeds.
Structure and Working Principles of Honda Accord CVT Transmission
Continuously Variable Transmission (CVT) and Automatic Transmission (AT) are automatic transmissions controlled by a hydraulic system.
However, the Honda CVT transmission differs from AT in the following aspects: CVT is a type without fixed gears, whereas AT has multiple gear ratios such as 1, 2, 3, and 4… similar to a manual transmission.
Let’s learn more about the structure, working principles, and meaning of symbols on the CVT Honda transmission.
Structure
The structure of a CVT Honda transmission consists of three components:
- A pulley system, including an input pulley connected to the engine’s rotating shaft.
- An output pulley drives the wheels.
- A high-power transmission belt made of either rubber or metal.
These three components work together to operate the CVT Honda Accord.
The pulley system, composed of the input and output pulleys, adjusts the effective diameter of the pulleys through the movement of the belt.
This variation in diameter changes the gear ratio, allowing for seamless and continuous power transmission from the engine to the wheels.
The transmission belt, made of durable and high-power material such as rubber or metal, transfers power between the pulleys.
Working Principle
“What is a Honda CVT?” or “How does the Honda CVT work?” – Two conical shapes form the input and output pulleys tilted at a 20-degree angle and opposite each other.
Inside the groove between the two conical shapes is a running belt, and the distance between them can be flexibly adjusted.
When the conical shapes move apart, the belt sinks deeper into the groove, reducing the radius of the wrapped belt around the pulley.
Conversely, when the conical shapes come closer, the radius of the belt also increases.
The necessary force to change the distance between the conical shapes can be achieved through either springs or hydraulic pressure in a CVT transmission Honda.
Typically, the pulley system and the belt diameter variations go hand in hand.
The input pulley (driving pulley) is connected to the engine’s rotating shaft and directly receives energy from the engine into the transmission.
The output pulley (driven pulley) is connected to the input pulley and transfers torque to the drivetrain, ultimately causing the wheels.
On the other hand, the radius of rotation refers to the distance between the pulley axis and the point where the belt wraps around.
The ratio of the input pulley’s radius to the output pulley’s radius of rotation determines the “gear ratio” of the transmission.
This means that as the radius of the pulley system changes, the corresponding transmission ratio also changes.
This is why the Honda CVT transmission has no fixed gears and can operate simultaneously with different engine types and vehicle speeds.
Meaning of Symbols on CVT Honda Transmission
- P: Parking mode, only used when the vehicle is at a complete stop
- R: Reversing mode
- N: Inaccessible mode, the car disconnects between the engine and the transmission, often used when pushing or pulling the vehicle…
- D: Driving mode, this is the primary mode used when the car is running

Notes to Maintain The Life of The Honda Accord CVT Transmission
To prolong the life of the gearbox, you need to use the gearbox properly.
The driver must switch the gear lever to the appropriate driving mode when using a continuously variable CVT transmission.
Here are some tips when using a CVT transmission:
Maintain Steady Throttle Input
Maintaining a stable throttle input contributes to fuel efficiency and reduces pressure on the transmission and engine.
An unstable throttle input can cause issues such as sudden acceleration, making it difficult to shift gears and affecting the vehicle’s overall performance.
To ensure a stable throttle input, it is essential to maintain a steady foot on the accelerator pedal while driving. Avoid abrupt throttle movements and accelerate gradually.
Do Not Rest Your Foot On The Brake Pedal
Resting your foot on the brake pedal while driving for an extended period can lead to premature brake wear and create unnecessary strain on the engine.
Therefore, avoiding resting your foot on the brake pedal while driving is essential.
This practice not only helps prevent rapid brake wear but also contributes to fuel efficiency and minimizes the occurrence of sudden braking, ensuring safety for the driver.
Limit Fast Driving
Driving at high speeds can result in rapid fuel consumption and strain the transmission.
Therefore, if this condition occurs frequently and for extended periods, users who regularly engage in speeding, reckless overtaking, or driving above the speed limit will decrease the variable transmission’s lifespan.
Switch Gears to Neutral Whenever Possible
Drivers should shift the CVT transmission to neutral (N) when stopping at a red light or when stuck in traffic to help reduce fuel consumption.
When briefly stopping at a red light, the driver only needs to keep the gear lever in the “D” (Drive) mode and should not switch back and forth between the “D” and “N” modes.
Doing so can decrease the lifespan of the valve system and the torque converter.
However, if the vehicle remains stationary at a red light for an extended period or when stuck in traffic, the driver can shift to the “N” (Neutral) mode.
Gentle When Going Downhill
Quick acceleration when going downhill can put stress and pressure on the drivetrain, leading to potential damage to the transmission and increased fuel consumption.
Therefore, to reduce strain on the transmission, it is advisable to exercise gentle acceleration when going downhill.
Conclusion
With the specific analysis mentioned above, we have the answer to the question, “What is the Honda CVT transmission?“.
Suppose you appreciate a smooth and gentle driving experience in a Honda vehicle while prioritizing fuel efficiency, cost-effectiveness, and durability.
In that case, the Honda Accord CVT transmission is suitable for you.
However, if that is not the case, you should opt for a traditional manual transmission to meet your commuting needs.
Once your CVT transmission experiences issues, you’d better take your car to the nearest transmission shops for timely repairs in performance transmission.
