Disadvantages of the Mercedes 722.8 gearbox

  • The main problems are caused by a control unit that often burns out due to overheating.
  • Friction wear products stick to the ECU sensors, which damages the board.
  • Intense driving on an unheated gearbox contributes to its rapid wear.
  • Dirt from the oil gets into the bearings, causing them to hum and subsequent destruction.
  • This CVT is very afraid of low lubrication levels, carefully monitor its level.
