Disadvantages of the XB-20LN gearbox
- 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.
