POWER TRANSMISSION - R POSITION

  • Reverse clutch 
  • Low and reverse brake 
 Front planetary carrier is stationary because of the operation of low and reverse brake.
Input power is transmitted to front sun gear through reverse clutch, which drives front internal gear in the opposite direction.
Engine brake As there is no one-way clutch in the power transmission line, engine brake can be obtained when decelerating.
