The "Primary" ratio is the Intermediate Shaft driving the Center Diff on an AWD or the Output Shaft on a FWD.
The "Secondary" ratio is the Output Shaft driving the Ring Gear on the Front Diff - the actual ratio of the axle shaft rotations compared to the tranny internals.
Primary x Secondary = final - this affects the rpm of the engine vs the rpm of the front axles.
Secondary/Transfer = Rear diff
The two must equal each other for an AWD car to roll without burning up the center diff (which is why you shouldn't run tires with different diameters F/R on an AWD).
