A Continuously Variable Transmission (CVT) does not use gears like a typical transmission. Rather, it uses two pulleys connected by a belt.
Depending on the vehicle and the driver, a CVT can provide a smoother driving experience when comparing it to a traditional automatic. According to Carfax, one of the most significant advantages to having a CVT is that they are often more fuel-efficient than a regular automatic.
A CVT likewise operates smoothly while climbing hills. This avoids the “gear hunting” you’ll often feel with a conventional automatic transmission. And because a CVT is lighter in weight and delivers better power efficiency, it helps improve a vehicle’s fuel economy. That’s why many hybrid vehicles come with CVTs.
Automatics Transmissions vs. CVTs. Automatic transmissions contain a complex series of gears, brakes, clutches, and principal devices. … A continuously variable transmission does not have individual gears, instead, it has one gear that is variable for all driving conditions.

CVT stands for continuously variable transmission and operates in a similar fashion to a traditional automatic.
But Nissan’s CVTs are also known for failing early on, which is why they’re the subject of many lawsuits. The transmissions are notorious for shuddering, making strange noises, overheating—and forcing the vehicle into a “limp” mode. Some would argue that Nissan’s CVTs are the worst transmissions ever built.
Replacing a CVT transmission costs roughly between $3,000 and $5,000 or higher. The CVTs won’t last nearly as long as the standard automatic transmissions, and it’s not surprising if they fail to run for more than 100K miles or less.
CVTs have been around for a while, but only recently have they become affordable and reliable. A CVT in a late model vehicle should easily surpass 100,000 miles with regular maintenance but older CVTs may not last as long. … A good CVT will last a very long time when taken care of.
|Driveability||Easy in stop-and-go traffic||Easy in stop-and-go traffic|
|Number of Gears||Single||Five to six|
Honda: The Civic Type R, Honda Fit (With the manual option), Honda Clarity, Honda Passport, Pilot, Ridgeline and the Odyssey are not equipped with CVTs. Hyundai: The Sonata, Ioniq, Veloster, Kona, Nexo, Palisade, Santa Fe and Tucson are not equipped with CVTs. Infiniti: The QX30 and QX80 are not equipped with CVTs.
CVTs are always adjusting, so they keep engine RPMs low and consistent, avoiding the high engine speeds that suck down gasoline. CVTs also have lower production costs because they have fewer moving parts than traditional automatics. This is another appealing factor to car manufacturers, and thus to car buyers as well.
Better fuel efficiency — Overall, manual transmission engines are less complex, weigh less, and have more gears than automatics. The end result is that you’ll end up getting more kilometres out of the petrol you pump in than you would with an automatic.
Most hybrids use small, efficient four-cylinder gas engines. … Hybrids typically come with some sort of continuously variable transmission (CVT). Some hybrids, usually European models, use conventional automatic transmissions or dual-clutch automated manual types.
Since there are no gears to upshift or downshift through, a CVT transmission will feel smoother in all driving situations, even when driving up steep hills. In essence, it’s like having a single gear that goes up and down the RPM, range instead of having gear for the engine to “step down” to with every gear shift.
In many ways a CVT gearbox is similar to a regular auto. For starters, there is no clutch pedal in a CVT-equipped car, so you can drive it on an automatic-only UK driving licence.
The L mode in CVT stands for “low gear” mode. In this mode, the transmission does not upshift by itself. Instead, it keeps running at a lower speed ratio to provide more power and torque when driving uphill. … This balance makes CVT ideal for driving in the hills.
The Amaze is the company’s best-selling car in the market that comes with CVT in both petrol and diesel. It is the first and only diesel-CVT subcompact sedan available in the country. The sedan can be had with CVT in three trim options – S, V and VX.
Though there are no gears in a CVT, some simulate a more traditional changing of gears. In these transmissions, the belt-and-pulley system is designed to move to preset points by using a traditional shift lever or paddle shifters on the steering wheel.
The Chrysler TorqueFlite A-727 (better known as just the ‘727’) is to this day one of the strongest automatic transmissions ever built.
Like any transmission, CVTs are susceptible to leaks at the seals and gaskets due to lack of use, overuse, overheating and even normal wear and tear.
The short answer is, no you cannot. The transmission control module and the entire powertrain wiring harness are designed for the car to have the exact CVT transmission. Despite the terrible reliability of these CVT transmissions, it is your only practical option for replacement.
Replacement can cost from $4,000 to $7,000, however if the fluid is changed every 40,000 to 50,000 miles the life of the CVT can be greatly extended.
The typical CVT lasts over 100,000 miles. Like any other transmission though, making sure that it’s taken care of will help ensure that you get as much life out of your transmission as you can.
Time and mileage vary between car drivers and how they use or abuse their transmissions. Still, typical automatic transmissions last around 150,00 to 200,000 miles or approximately 7 years. Cases exist in both extremes; extreme longevity and early failure.
Are CVT Transmissions Good for Towing? CVTs work well in small and medium cars and SUVs and are better suited for fuel-efficient city driving and moderate load. If you plan on using your vehicle for towing a trailer, a conventional automatic transmission with a fixed number of gears is a better choice.
Disadvantages of automatic transmissions system :
Maintainance is costly. … Fuel consumption is also higher than a manual transmission. Automatic transmission consumes 10% more than a manual transmission. Take a longer time to change gear between high and low.
Lexus and Toyota — which rely on older transmissions in many of their models — were the best-performing brands in the survey. Lexus or Toyota has topped the survey since 2011. Audi, Mazda and Subaru rounded out the top five. The worst performers were Infiniti, Cadillac, Ram, Jeep and Fiat among 28 brands.
