So How Does a Constant Variable Transmission (CVT) Work?

Decades ago car makers offered automatic transmissions with two or three forward gears or "speeds".

Over the years traditional automatic transmissions have evolved to the point where they are now being delivered with six, eight, ten or even more gear ratios. The advantage is smoother power delivery and improved fuel mileage but even so, your vehicle's transmission may not have the ideal gear for your speed and load at any given point in time.

The CVT design uses two pulleys bound together by an extremely strong steel belt instead of multiple gears. The diameter of one of the pulleys constantly changes to maintain the engine's RPMs at the most efficient level for the specific driving situation at that moment. CVTs don't have fixed gears like conventional automatic transmissions so a driver never experiences the sensations of gear changes.

A Constant Variable Transmission relies on a single steel band, so it's gear ratios are almost infinitely variable. Because the engine never has to stop sending power to the wheels, the CVT can always find the most efficient ratio.

By having the optimum gear ratio available with a CVT, your engine can get better fuel mileage while providing a smooth ride without gear noticeable shifts.

The benefits of CVT are seamless, power delivery and improved gas mileage. The shortcoming of this technology is that this design depends on a single metal band. There aren't many other parts that can go bad on a CVT but when that metal band breaks, the transmission is completely disabled and the vehicle is can't move forward or back. Hundreds of tiny metal fragments and pieces of the metal strands and that hold the belt together will have traveled through the transmission and will certainly have damaged the drive and reverse gears and even the transmission case.

How CAN A CVT Transmission Be Repaired?

Sadly, a "repair" isn't possible. Once the belt snaps it cannot be replaced. The only remedy is install a new or professionally rebuilt transmission. It's not uncommon for dealerships to charge up to $8,000 for a new CVT. If you need CVT Transmission repair in Sacramento, your only option is to install a rebuilt or new CVT transmission.

Our shop recommends replacing the CVT drive belt at 60,000 miles. Although this preventative measure costs around $4,000, it's much cheaper than replacing the whole transmission and it would be essentially renewing your transmission for another 60,000 miles. While a CVT tranmission repair is not practical, this maintenance step will keep your transmission running like new!

Subaru was the first company to offer a CVT in the U.S. and currently Audi, Honda, Hyundai and Toyota all manufacture their own proprietary CVTs. Nissan doesn't build its own CVTs because it owns a controlling interest in JATCO, the firm that supplies just under half of the world's gear-free transmissions to Chrysler, GM, Mitsubishi, and Suzuki. Nearly half of Nissan's current U.S. models can be ordered with an optional JATCO-supplied CVT.


Each transmission is built from start to finish as a whole unit independent from all others.

First, the transmission is broken down and cleaned by our teardown department, and then inspected. It then goes into a hot wash and is brought out to be re-inspected by the prep department, which takes the cases to the polishing station for further cleanup.

The valve bodies are placed in an ultra-sonic cleaning station after the builder tears them down and inspects all springs and pistons. All pistons are then hand polished to a mirror finish, thus removing all imperfections, and the valve bodies are washed for a third time.
