Your statement on the t/case fill is partially correct for some vehicles, and incorrect of other vehicles.

For vehicles built prior and including 5GTDN136968105387, you just don't remove the sensor and fill to the sensor. You fill to the fill hole, as you described, and then remove the speed sensor and ADD ADDITIONAL 8.45 oz of fluid through the sensor hole.
If the vehicle was manufactured after the above VIN number, the additional fluid is not required.

In addition, the front diff also requires SAE 75W-90 Synthetic Axle Lubricant.

As to changing it prior to recommended specs, it's your money.
