ok lets take a following example:
-mass of the car: 1500kg
-parked on a 30 degree slope
-0.3m tire radius
-3.07 axle ratio
cars weight on earth: 1500kg x 9.81 = 14715 Newtons
force pulling on the car on a 30 deg slope: 14715/2 = 7358 Newtons
torque on the braking wheels from this force: 7358 x 0.3 = 2207 Newton-Meters (Nm)
torque on the driveshaft (tranny output yoke) = 2207 / 3.07 = 719 Nm
So as you see torquing the nut to only 120 Nm is not a problem because the parking pawl is designed for a lot more torque.
719 Nm is just to hold the car in place. When you put the car in park while slightly rolling the peak forces are way higher than that
