I have recently had a strange problem occur with my 04 3l td patrol manual, and hope someone can give me some advise as to the cause.

On merging into freeway traffic the vehicle maintained and even increased engine speed, but at the same time lost road speed. At first I thought that the clutch must be slipping, so once I got the vehicle safely off the road couldnt smell any indication of slippage. next step I carried out a stall test by putting the vehicle into 5th gear and trying to stall it, it stalled which is a fair indication that the clutch is ok. Also there arent and havent been any signs of clutch trouble during any stage of driving. And there shouldnt be as Ive only just completed the 30k service.

No signs of fluid loss (rear main leak wetting clutch face) or clutch fluid. The only thing that comes to mind is a small vacuum leak every now and then, but only prior to start up.

A gear box/ diff speciallist has mentioned that there is a possibility of a slip occuring within the transfer case, that causes partial drive to the rear prop shaft and majority drive to the front shaft, but unless your hubs are set to lock you will have a feeling of slippage.

I have had the vehicle towed(tilt tray) to nissan and as its under warranty hopefully they will remedy the problem, But I would really appreciate some unbias input as I DO NOT trust nissan sevice, thats another story.
