The CVT is an automatic transmission that uses two pulleys with a steel belt running between them. To continuously vary its gear ratios, the CVT simultaneously adjusts the diameter of the “drive pulley” that transmits torque from the engine and the “driven pulley” that transfers torque to the wheels.
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.
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.
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. These are a couple of things you can do to increase the lifespan of your vehicle’s CVT.
Many manufacturers such as Subaru, Honda, Nissan, and Toyota use continuously variable transmissions on their most popular models. If you are shopping for a new Prius, Civic, Accord, Corolla, Forester, or Outback, don’t let a CVT automatic concern you. CVTs have proven enjoyable and reliable for many vehicle owners.
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.
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.

CVT stands for continuously variable transmission and operates in a similar fashion to a traditional automatic.
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.
|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.
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.
Can you tow with a CVT? There’s no problem whatsoever when it comes to towing a trailer with a vehicle equipped with a CVT transmission as long as you don’t exceed the vehicle’s maximum towing capacity or maximum allowable weight when passengers and cargo are taken into account.
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.
In today’s marketplace, new cars with CVTs can be expected to provide reliable operation up to about 100,000 miles. For most cars, overall reliability will be poorer than that expected with a conventional automatic or manual transmission.
Generally, the issues have been reported between 2012/2013 and 2018. There were some problems in 2003 when Nissan first began using this transmission and in the 2007-2012 CVT generation. Specific models include the Murano, Sentra, Altima, Rogue, Versa, and Versa Note.
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.
You can probably tell by now, the most important maintenance for your CVT transmission is the upkeep on the fluids. The time interval that you can drive between fluid changes will depend on your vehicle. For example, Nissan will recommend that you change the fluid every 25,000 miles.
Keep in mind that the CVT is not serviceable. Meaning, you cannot replace the belt alone, you have to replace the whole unit if it fails. Once you open the CVT casing, it is no longer functional. Or at least this is what CVT manufacturers tell consumers.
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.
CVT transmissions offer a better torque ratio.
That’s why you can find yourself being passed by a small hatchback in a V8 when climbing a mountain pass. The smaller vehicle climbs better thanks to the ever-present ability to find the best gear ratio possible in every circumstance.
The belt between the pulleys results in what is commonly known as the ‘rubber-band’ effect. Essentially, this is when there is a lag between when you dab the throttle, resulting in rising revs and where the power is transmitted to the wheels.
