Four Wheel Drive Low Range

This mode operates the same as 4WD high (4H) but in addition the torque delivered to the transfer case from the transmission passes through a planetary gear set which multiplies the torque by the given ratio. (In the case of the Advanced 4x4 with 4A Mode transfer case the ratio is 3.06:1) While the torque is increased by 3.06 the output speed from the transmission is reduced by the same 3.06 ratio.
