2WD 2.8 is 5HP19 correct?
So not the same problem areas as 5HP24A necessarily.

My basic premise when it comes to gearbox servicing is that "filled for life" is total BS. "Filled for warranty" is more accurate.
ATF contains friction modifiers, corrosion inhibitors, and other sacrificial elements. All of it is consumable.
Heat and stress cycles will break down the oil viscosity over time, particularly once the consumables are all used up.

I am convinced that regular oil changes will prolong the life of any transmission - provided you get to it early enough.
My interval is 40-50,000km - so 25-30,000 miles.
