The XTRONIC CVT is the first to feature a sub-planetary gear, which reduces overall size and weight and increases efficiency. 'In 1993, the CVT was banned from the world's most prestigious racing series. It was considered an unfair advantage.' Current Nissan Models with XTRONIC CVT. XTRONIC CVT, we enhanced real-world fuel economy based upon simulations of typical driving conditions. Powerful and satisfying acceleration feel CVT performance is characterized by stepless shifting and seamless acceleration. To reﬁ ne these advantages, we signiﬁ cantly improved gear shifting response in the XTRONIC CVT to provide tighter.Besides, what is CVT with Xtronic transmission?
CVT (Continuously Variable Transmission) is a system with seamless, “stepless” gear transmission. XTRONIC CVT is suitable for 2.0-3.5-liter displacement engines, achieving an improvement in fuel economy of up to 10% compared to standard CVT, and delivering the feel of a more direct drive.
One may also ask, what is the difference between CVT and Xtronic CVT? In a sense the XTRONIC CVT is an automatic transmission, but it differs in that the CVT does not have fixed gears like an automatic transmission does. The XTRONIC CVT uses two pulleys with a steel belt running between them. Additionally, the XTRONIC CVT has less moving parts than a traditional automatic transmission.
Keeping this in consideration, is CVT better than automatic transmission?
A CVT draws top engine power from a small engine, which gives drivers quicker acceleration than standard automatic transmissions. Because of their greater ability to control the engine speed range, CVTs produce fewer emissions. CVTs are also lighter weight than traditional automatic transmissions.

Nissan CVT problems
Nissan introduced its first constantly variable transmission (CVT) in 2002 and it immediately began showing problems with difficulty accelerating, shaking / stuttering, running hot, and suddenly shutting down. Nissan addressed the root cause of those problems and upgraded the transmission. Luckily, Nissan would go on to address most of those concerns. But that didn’t end the problems with Nissan’s CVT transmissions. Even the most recent Nissan CVT transmissions are failing early and often.

Nissan sales fall due to CVT problems
Due to their frustratingly poor reputation, buyers are shying away from both new and used Nissan products and that’s reflected in recent sales slowdowns. The problem is so serious that Nissan was forced to slash its profit outlook on April 29, 2019 to reflect falling sales and rising CVT transmission warrant costs. Nissan has had to dedicate an extra $590.5 million to cover the cost for these extended warranties.
Nissan has also been forced to extend CVT transmission warranties again, this time to seven years from the previous five years. The warranty extension covers over 3,000,000 vehicles sold from 2012 to 2017 and covers models Sentra, Versa and Altima sedans.
Nissan CVT symptoms
Nissan CVT transmissions are known to run hot and cause premature failure. Some speculate that the cause of the overheating is undersized cooling systems. When the Nissan CVT overheats, driver’s complain of shaking, shuddering and vibration while accelerating and an overall lack of acceleration. As the Nissan CVT self destructs, the computer puts it into a fail-safe mode which limits engine RPMs to prevent even worse damage.
When Nissan CVT transmissions fail
Reports from owners show that Nissan CVT transmission fail, on average, at about 64,000 miles. Worse yet, a replacement Nissan CVT doesn’t last any longer than that. So drivers can expect to replace their CVT transmissions several times during the car’s lifetime.
Any way to prevent Nissan CVT transmission failure?
Not really. Since Nissan’s CVT transmissions are very susceptible to overheating, changing the transmission fluid often is critical to reducing early failure. But that won’t prevent it entirely. The root cause of the early transmission failures are in its design and cooling and there’s nothing owners can do to eliminate that early transmission failure.
