Hey mate
New here, but first thing I would be looking at is the oil level - service has been mentioned, but without oil pressure in the valve body, the gears will "flare" in between changes which sounds just like you describe, and being sequential in changes, without pressure to the valve body (to do it's "thing") you would be possibly suffering lack of ability to change up to higher/taller gears.

Hope you haven't cooked it, as that won't be resolved by simply topping up/changing the oil - rule of thumb with auto boxes is "keep them cool, keep them for life" ... if the oil has been low for some time, you may have cooked it and that is far from a "pension friendly" issue sorry to say ...

Nissan Patrol gearboxes (like everything on them in general) are high maintenance, attention seeking whores - but just like whores, keep throwing the $$$ into them in the "right" spaces (doesn't mean break the bank) and they'll keep performing just like you've paid for!

All the best ...

Oil levels are fine

Was it a mechanic that checked the levels or yourself, if you did it yourself did you heat up the gearbox oil and run through your gears or was it checked cold???
