GU IV Clunky drive train????

Get someone to get underneath with the vehicle in gear and not running, try to turn the tailshaft and see if anything like uni's etc are not misbehaving otherwise it's the gearbox with some slack.
Maybe get a mechanic to have a look for you and advise.

G'day Babs,
Not sure whether this is your first big Nissan mate, but all the ones I've had have had a clunky feel to the box. They are, after all, out of a truck. To me it's kinda reassuring changing gears in the GU.....it's something that should not (cannot) be rushed. I tend to move the gear lever slowly and deliberately, pausing in the middle gate before moving onto the next cog.
Don't suppose this answers your question, but it might give you something to think about (;-))

Have a look underneath your vehicle and note the physical size of the gearbox. Compare this to a landcruiser, prado etc and you will see the gearbox in your patrol is substantially larger. My Gu has a gearchange that is slower and clunkier than a troopy, to use a example of another 4wd I regularly drive, largely due to the size and mass differences in the components involved. Once you get used to the patrol and as roachie says slow down your changes or double clutch then you don't really notice it anymore. This is what I have found, as I was also struck by the clunky gearbox, having driven mainly cruisers in the past.
Cheers
