The SST transmission is a first generation DCT from Getrag. Unfortunately, that means it comes with some common issues effecting reliability, which include:

  • P184b Code (loss of even gears)
  • Shift Fork Magnet Failure
  • Not Repairable at the Dealership
  • Oil Pump Lubrication Failure (ironic…)
  • Torque Damper Spring Failure
