| Command Shift to manually select a gear when off road |
|
If you put the gearbox in D and then use the paddles to select a specific gear, it stays in that gear for about 10 seconds before reverting to full auto. This is handy for a quick over take, but not so good when off road.
At my LRE day last week, when in Mud Ruts, low range and with HDC on, and the gearbox in D, the D4 seemed to stay in the manually-selected gear. I wasn't sure which of the settings, or combinations thereof, caused this behaviour. Is it Mud Ruts, low range or both that causes this?
When I get time, I'll try the different combinations, but does anyone have any info on when the gearbox stays in manual?
Cheers

S mode on the 'box.

That changes the gearbox so it doesn't upshift so soon - not always what you want e.g. on slippery surfaces. So, you drive along in D, then want manual, so switch to S, use the paddles, then want auto again so need to switch back to D. Not a disaster, but given the car can do fully-manual in D, just trying to work out what settings cause that to happen. MY16 D4 Graphite in Loire Blue

It seems so long ago since I drove the Disco off road but I 'think' when you are in a terrain response mode, eg grass/gravel, mud ruts etc and you use the paddles the car will stay in manual mode unless of course the car detects that you are screaming along in 1st gear it will then change up. Is that what you mean or have I read your post wrong? Cheers Ian

Yeah, that's what I mean 
I didn't know if it was the combination of a TR programme, low range and HDC that did it, will try just a TR programme. MY16 D4 Graphite in Loire Blue

I don't think it matters.... I think it changes up if you rev too hard for too long. Likewise it changes down if it thinks you'll stall. Sill protection - LED internal lights - LED reverse lights - boot liner - Dog Guard - Rock sliders

They must have taught me wrongly at LRE then. But the question was - how to get manual control. The answer is, put the 'box in S and use the paddles (on or off road). The box isn't going to upshift later, because you're controlling it manually. If you want auto, leave it in D.

I wonder if the gearbox functions have changed and therefore the guidance from LRE is different? We spent the day at LRE last week in D and I was able to manually select gears. As per previous posts, this happened when in Mud Ruts, low range and HDC.
It is all academic really as I'm not taking my car off road much yet. I just like to know how this stuff works. I can feel a spreadsheet coming on... MY16 D4 Graphite in Loire Blue

It sounds like it should be the case that manual control kicks in when mud & ruts / low range is selected - I'll give it a try.
And do take your Disco off road - it's what it's for! You should be able to find some "mild" green lanes nearby (though wait for the drier weather).

I know - but it is still shiny outside and has that new car smell inside. By Spring next year that'll have worn off, so will start using it. I was blown away by what we did at Eastnor, and that was the beginners stuff.
Is it worth joining a local or national green laning club? MY16 D4 Graphite in Loire Blue

On joining a green lane club...
I'm in two minds. On the one hand, it's advisable to go with other people in case you get stuck (ask me how I know). Plus a local club will have good knowledge of suitable green lanes, TROs (closures) and the current state of the lanes. You don't want to end up in a quagmire or cause damage to the lane or your Disco.
On the other hand, a lot of green laners seem to be of the checkerplated Defender with giant tyres persuasion. Perhaps ask here to find others where you live and sound them out.
