Hi Dfourfun,
there is your issue, if you leave the gearbox in "D" this will cause the vehicle to stall on climbs as there are 2 many choices for the ecu to choose from. The vehicle bogs down & in its choices to find the correct gear you stop!

When climbing use 2nd gear :)

Cheers

I also have experienced this in the long, steep sand dunes of Calcup. Whilst climbing, engine power was being cut then returned then cut back again. It is like the engine is 'surging' up and down through the rev range irrespective of moment of the accelerator pedal on my part. My settings at the time were Hi range, Sand mode, Drive and I also swear DSC was off at the time.

The 3.0L easily had enough power to climb those dunes in high range until 'whatever' decided to reduce the engine power and bring it to a halt. Another run at the same hill with the same setting saw it get to top in high range easily but for whatever reason the engine surging up and down did not re occur again.

Thanx Sneigy, I must say I didn't think of specifying a gear manually. :o I will give it a go this weekend. As a (former) Pajero man I have always worked on the basis that it was auto on the up slopes and manual selection on the down slopes... I obviously need to re-learn some driving techniques with this Disco beast. I have needlessly been cursing LR when I should have been looking in the mirror. Thanx for pointing out the error of my ways. Cheers!:)

I tried selecting second, but it would still kick to first, then to second, then to first. I tried to lock it in first, but the same thing happened for me, will still go up then down then up....was super annoying.
Hopefully it works for you.

Ebay stores and RoverLord switches say compatible 2005-2010 model D3 D4 & RRS. Does anyone know if it is the same part # for the 2011-2013. 3.0 SDV6

Having now bought & fitted one the answer to my question is Yes! Also it appears that the same part is also used in the Ford Territory so could be handy if a Ford dealer is closer than the Landy dealer.
