  • The life of a continuously variable transmission depends entirely on the frequency of oil changes;
  • Old and dirty grease clogs the bearings, causing noise and rapid wear;
  • CVT is afraid of overheating due to slipping or long driving in traffic jams;
  • Rarely, leaks from drive seals do occur, which is very dangerous for the gearbox.
