How Subaru CVT Works: A Comprehensive Guide

How subaru cvt works – Dive into the world of Subaru’s Continuously Variable Transmission (CVT) and discover how it revolutionizes the driving experience with its unique blend of efficiency, smoothness, and performance.

This comprehensive guide unravels the intricacies of the Subaru CVT, taking you on a journey through its components, working principle, advantages, and maintenance requirements.

Components of Subaru CVT

A Subaru Continuously Variable Transmission (CVT) is a type of automatic transmission that uses a belt or chain to transmit power from the engine to the wheels. It consists of several key components that work together to provide smooth and efficient power delivery.

Torque Converter

The torque converter is located between the engine and the transmission. It acts as a fluid coupling, allowing the engine to idle without stalling the transmission. When the engine speed increases, the torque converter multiplies the torque output of the engine, providing smooth acceleration.


The CVT uses two pulleys, one connected to the engine and the other to the transmission. These pulleys are variable in diameter, allowing the transmission to change the gear ratio continuously. As the engine speed increases, the diameter of the engine pulley decreases, while the diameter of the transmission pulley increases, resulting in a higher gear ratio.

Belts, How subaru cvt works

The belts are made of a flexible material, typically steel or rubber, and are responsible for transmitting power between the pulleys. As the pulleys change diameter, the belts adjust their length to maintain contact with both pulleys, ensuring smooth power transfer.

Subaru’s CVT, or continuously variable transmission, is designed to provide a smooth and efficient driving experience. It uses a belt and pulley system to transfer power from the engine to the wheels, allowing for seamless gear changes.

Coming back to the CVT, it’s known for its durability and can handle the demands of everyday driving.

Working Principle of Subaru CVT

The Subaru CVT operates on the principle of continuously varying transmission, allowing for seamless and efficient power delivery across a wide range of speeds. It consists of two variable-diameter pulleys connected by a flexible metal belt. The pulleys are designed to move closer together or further apart, altering the effective gear ratio and eliminating the need for traditional fixed gears.

The Subaru CVT, or Continuously Variable Transmission, is a type of automatic transmission that uses a belt or chain to connect the engine to the wheels. This allows for a smooth, seamless driving experience without the need for traditional gears.

If you’re curious about other Subaru models, you might wonder does subaru make a truck . While Subaru is known for its cars and SUVs, it doesn’t currently produce any trucks. However, the Subaru CVT is still a great choice for those who want a reliable and efficient transmission.

Adjusting Gear Ratio

The adjustment of the gear ratio in a Subaru CVT is achieved through hydraulic pressure. A hydraulic pump, driven by the engine, generates pressure that is applied to the pistons within the pulleys. As the hydraulic pressure increases, the pistons push against the pulley surfaces, causing them to move closer together, resulting in a lower gear ratio.

Conversely, when the hydraulic pressure decreases, the pistons retract, allowing the pulleys to move further apart, resulting in a higher gear ratio.

Advantages of Subaru CVT

CVTs offer several benefits over traditional automatic and manual transmissions.

The Subaru CVT, or continuously variable transmission, provides a smooth and efficient driving experience. It constantly adjusts the gear ratio to keep the engine running at its most efficient RPM, which can save you fuel. The Outback is one of Subaru’s most popular models, and it’s known for its towing capabilities.

Improved Fuel Efficiency

CVTs can improve fuel efficiency by up to 10% compared to traditional automatic transmissions. This is because CVTs can operate at a continuously variable ratio, which allows the engine to run at its most efficient speed.

Smoother Driving Experience

CVTs provide a smoother driving experience than traditional automatic transmissions. This is because CVTs do not have any gears, so there is no shifting or jerking.

Better Acceleration

CVTs can provide better acceleration than traditional automatic transmissions. This is because CVTs can keep the engine in its power band, which allows for more power to be delivered to the wheels.

Maintenance and Care of Subaru CVT

Maintaining a Subaru CVT requires specific care to ensure its optimal performance and longevity. Regular fluid changes and filter replacements are crucial for the transmission’s health. Fluid changes should be performed according to the manufacturer’s recommended intervals, typically around 60,000 to 100,000 kilometers.

Using the correct CVT fluid is essential, as specified in the owner’s manual. Additionally, the CVT filter should be replaced during fluid changes to remove accumulated contaminants.Regular inspections are also important for early detection of any potential issues. These inspections should include checking the fluid level and condition, as well as listening for any unusual noises or vibrations.

If any abnormalities are detected, it is advisable to seek professional assistance from a qualified mechanic.

Potential Issues and Troubleshooting

CVTs, like any mechanical system, can encounter potential issues. One common problem is shuddering or slipping, which can be caused by worn or contaminated fluid. In such cases, a fluid change and filter replacement may resolve the issue. Another potential problem is overheating, which can occur due to excessive towing or driving in extreme conditions.

If overheating occurs, it is important to allow the transmission to cool down and seek professional attention.Regular maintenance and care are essential for extending the lifespan of a Subaru CVT. By adhering to the manufacturer’s recommended maintenance schedule and addressing any potential issues promptly, you can ensure the smooth and efficient operation of your CVT for many years to come.
