Read it somewhere that it has less wear and tear then a4t
If its belt (or chain) keeps in good condition it will last long then normal a4t transmission.
One more thing to note that modern day automatic transmissions in bigger cars are different bec they have 6 or more gears
And the CVT in modern cars in bigger category have more then 10 gear ratios.
Anyway all i searched and found out is that newer technology is CVT now and more and more cars are converting to that only bec of better economy.
