Just ordered all new fluids for my QX4, motor, tranny, transfer case, front-rear diffs, brakes and an oil filter...all Amsoil. Not entirely sure if I should change my transmssion filter(89K on vehicle))? Do the diff covers have to be removed...seals? Anyone done this kind of a lube swap?

i also just recently changed all my fluids to amsoil. as for your tranny there is no filter just a screen so you do not need to drop the pan and change it. nissan says to leave it. i pulled mine just because and flushed it out with new tranny fluid but it was not even dirty at 69k. for your diffs there are fill and drain pugs no need to remove the cover. just make sure to remove the fill plug first as it tends to stick much harder. when you do your tranny, pull the plug and after it is done draining start the q and move the tranny between gears for about 10-30 seconds to get the fluid out of the tranny cooler. amny fluid you leave in there will degrade the life of your amsoil as per there website. overall very good oil from amsoil my gas mileage went up about 1-2mpg and everything is much smother running.
