CVT Disadvantages

lol, the disadvantages that wikipedia has listed are quite humorous as they pretty much are advantages in reality. That and it describes the Typical American thought process when it comes to the way things should work.

Advantages

  • CVTs operate smoothly since there are no gear changes which cause sudden jerks.
  • Very few problems have been reported with the CVT transmission, lowering the cost of ownership.[citation needed]
  • The fluids do not have to be changed as often as in an automatic transmission.[citation needed]




    Heres the oddity that makes it seem like they couldn't find a good
    enough reason to down the CVT, so they scrapped together this
    Info. This explains why the regular american driver looks down at
    his foot and goes "What the F***!!!" when they use the CVT
    for the first time.

Disadvantages

  • CVTs operate smoothly and efficiently, without spending energy to jerk the car during a shift. This can give a perception of low power, because many drivers expect a jerk when they begin to move the vehicle. However, the expected jerk of a non-CVT can be emulated by CVT control software, thus eliminating this marketing problem.[citation needed]
  • Since the CVT keeps the engine turning at constant RPM over a wide range of vehicle speeds, pressing on the accelerator pedal will make the car move faster but doesn't change the sound coming from the engine as much as a conventional automatic transmission gear-shift. This confuses some drivers and, again, leads to an impression of a lack of power. This can be considered a disadvantage if the driver desires to hear the engine change tone.
  • CVT torque-handling capability is limited by the strength of their transmission medium (usually a belt or chain), and by their ability to withstand friction wear between torque source and transmission medium (in friction-driven CVTs). CVTs in production prior to 2005 are predominantly belt- or chain-driven and therefore typically limited to low-powered cars and other light-duty applications. Units using advanced lubricants, however, have been proven to support any amount of torque in production vehicles, including that used for buses, heavy trucks, and earth-moving equipment.
