Savannah Buzz, slipping into neutral all vibration disappears. How do I check for a slipping transmission?

ljdiscovery, the donut looks to be fine - no obvious cracks or other damage. As to whether it's a rumble or a vibration, it's both! Difficult to describe - sometimes it feels like poor road surface at other times you can hear and feel a low frequency droning harmonic that causes the complete vehicle to vibrate. I would guess the frequency to be about 2 per second. This can also be felt through the diff lock (I have a disco 1 CDL fitted, so I imagine the mechanical linkage transfers the vibration better than the cable operated D2 version).

I carried out the stall test described in RAVE, only reaching 1700rpm, which suggests my engine is low on power. Not sure if this would be contributory?

Given that the noise / vibration disappears when slipping into neutral, I'm tending towards transmission or transfer box. Does this seem reasonable? I'll try a fluids and filter change and see if there is any improvement...

Thanks for the replies, Gents.
