is cvt good or bad?

CVTs are not without mechanical problems, and as with conventional automatics, it can be expensive to repair or replace a CVT. Search the website www.carcomplaints.com and you'll find a number of common issues with CVTs. These include overheating, slipping, jerking, shuddering and a sudden loss of acceleration.

Ways a CVT is Better Than Automatic Transmission In terms of practical advantages, the CVT transmission offers better fuel efficiency, less engine jerk (due to a lack of up- and downshifting), and, that's right—reliability.

Turbochargers are a Engine component and the CVT a transmission component, there is no reason for a CVT not to work with a Turbo if tuned correctly. CVTs require fine tuning to the engine curves, so if you are planning to Turbo a normally aspirated engine with a CVT to a turbo you have to be careful.

CVTs aren't as popular because a lot of people are used to driving normal torque converter automatic & manual transmissions. So they probably couldn't get used to how CVTs work.

Unlike AT, that has fixed number of gear ratios, generally 5-7, CVT has infinite number of gear ratios between minimum and maximum value to deliver the required amount of power for driving. ... AT have fixed number of gearbox while, CVT does not have a gearbox with set number of gears.

This is the actual drive mechanism of the CVT. ... This is not a transmission robust enough to handle high HP/high torque engines. It is best suited for small, low HP engines where it's almost infinite gear ratios can wring the best power and torque from a smaller engine.

A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps.

Since neither the pulleys or the belt are fixed, they can provide an infinite number of gear ratios, unlike the automatic, which has a set number of gears. Not all CVTs are created the same.

Which CVT Transmission Brand Is The Most Reliable? The Honda models with the CVT are the most reliable among all the lineups and CVT transmission life expectancy is the longest. However, the automakers have been working relentlessly to improve the technology.

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.

A CVT is a substitute for a gearbox as you see in motorcycles where you need to shift the gears all the time. A CVT manages to adjust the gearing automatically according to your speed and power(torque, precisely). ... There is a belt and two pulleys, in the grooves of which, the belt moves.

The Honda models with the CVT are the most reliable among all the lineups and CVT transmission life expectancy is the longest. However, the automakers have been working relentlessly to improve the technology. Almost all the newer models of the brands are better than their predecessors.

I'd say the Nissan CVT is certainly reliable. Not only that but it is very responsive compared to your average econobox auto, and mated to a V6, a lot of fun. Nissan seems to believe in their CVT as they have them in the vast majority of their vehicles. Statistically they are reliable.

Nissan CVT Problems. ... These problems call the Nissan CVT transmission reliability into question and can result in serious harm to unsuspecting drivers. Nissan extended the warranty on some of these vehicles equipped with the CVT transmission from 5 years or 60,000 miles to 10 years or 120,000 miles.

Question: “Are CVT transmissions really that bad?” No. they are really quite good at very efficiently transferring power while smoothly varying the gear ratio to efficiently use the engine's torque. ... You see, a conventional manual or automatic transmission changes its gear ratios in discrete steps…

Unlike conventional automatic transmissions, continuously variable transmissions don't have any gears. A CVT uses two cone-shaped pulleys. One pulley is connected to the engine and the other is connected to the rest of the transmissions.

CVTs have limitations, but they're not bad. Because they are belt driven and not gear driven, they can slip under high torque conditions. But within parameters, a CVT is superior to a geared transmission. The CVT allows an engine to operate at peak power or peak efficiency regardless of output speed.
