Look carefully at all the symbols on the car, the engine and in the accompanying documents. Automatic transmission is often denoted by the letters A or at. The CVT is always indicated by a combination of characters CVT.
Gather as much information about the car. Sources of information can be a variety of automotive publications, catalogs, Internet, technical and reference literature. This way you will know exactly the type of transmission, which could be installed on a particular brand of car.
Do a test drive on the car. The main difference of the variator from the machine is that a gear in the machine gives the characteristic perceptible tremors with a simultaneous change of the number of revolutions, which can be defined as the tach and by ear.
Note that modern variable-speed drives with fixed ranges with the measured drive fairly accurately replicate the operation of the machine. Therefore, the lack of aftershocks can be determined only by dynamic acceleration. Engine with a CVT with a sharp pressing the gas pedal "hangs" at a certain number of turns, and the car accelerates without bumps and when stationary the needle of the tachometer.
During the trip, find a stretch of road with driving uphill. Will slow down the car and release the brake pedal. The machine will not fall back, and start slow movement forward, the CVT on the contrary - slightly set back, and movement at idle will not. This method of determining suitable only for those CVTs that have no stop mode when rolling.
Ignore the recommendations, advice to distinguish between automatic and CVT for signs of modes of their work. It's too unreliable option, very different depending on the brand and model of the car. In addition, the designation of the modes on the machines and CVTs may be the same.
If you are still in doubt about the type of transmission installed, the final answer will receive the branded service stations. Experienced professionals will first look at the bottom of the car to say CVT or automatic.
Advice 2: Automatic or CVT: experts
All motorists know that in a manual transmission – five speed, automatic box – about eight and a CVT has an infinite number of gears. So what is better to choose an automatic or CVT, and what their functions should be guided by the choice?
The advantages of CVT
A variator is a device between the engine and the wheels, which allows for maximum smoothness to change the rotation speed of the master and slave drives. Traditionally, variable-speed drives are used in mopeds, scooters, snow and water scooters, however, it has recently been implemented in modern cars. Unlike automatic, the CVT moves much smoother accelerating as a powerful motor – in the set speed there are no failures and loud noises.
A vehicle with a CVT accelerates more rapidly the more powerful machines by saving time on the gear shift.
Compared to the automatic transmission, according to the set rpm the CVT is the clear leader. In addition, a car with a CVT does not stall at traffic lights and not roll back at uphill, and starting off is always very smooth, regardless of the skill of the driver. Some motorists don't like smooth and constant hum of the motor caused by the variator, and the absence of beloved by many men "sporty growl" under hard acceleration of the vehicle. This is because the variator in a timely manner optimizes the operation of the motor, not allowing it to reach critical values.
What to choose?
Some car owners prefer the CVT because it is more silent compared to the automatic transmission, fuel economy, rapidly accelerates the engine and other drive components are more optimized load. In addition, the CVT, unlike a machine, working in a sparing mode, which provides e-governance. The result is a car much less maintenance and almost never needs repair variator.
The CVT also has a positive effect on the environment the level of harmful substances in its exhaust gases is much lower than in gases machine.
Fans of the classic gearboxes can buy a variator with Tiptronic emulator switch speed settings. Lovers of speed and power will appreciate the CVT with a "kick-down", through which the sharp pressing the gas pedal to the max instantly changes the gear ratio and the car is accelerating at lightning speed, literally. Thus, the CVT has more advantages compared to automatic transmission.
