this might be stating the obvious, but it has to be in Neutral on the main box for you to change on the transfer box. Put main box in neutral, then try moving the transfer box leaver forward. It sometimes helps if your moving very slowly, or if your on a slight hill, let the car roll slightly as you move the leaver.
Other than that, it might just be stiff if it hasn't been used for a while. try the common faults area, think there is a link somewhere to freeing stiff boxes.

As Rob says the autobox lever must be in N, then give the smaller lever a firm shove forward. Then when you select D, you'll feel it in !!!!
You're familiar with the difflock operation I take it??

Ok, in that case you need to be aware that there are two, separate but related functions that are controlled by the smaller of the gear levers.
One function is the high and low ratio of the gearbox - in normal road driving you need to be in high. In low ratio this gives you much greater control at slower speeds and when off-road. Low ratio with the autobox is best selected at standstill. I find low very useful when reversing trailers in confined spaces for example.
Difflock is the other function. This works on the basis of "locking" the centre diff - hence the name. You would use this if you are on surfaces of low traction eg mud, snow etc and can be used in both high and low ratio. It can be selected by sliding the small lever to the left and a light will come on the dashboard to show it's working. DO NOT EVER SELECT THIS IF ANY OF THE WHEELS ARE SLIPPING !!!
As soon as the vehicle is on firm ground again, de-select difflock and the light will go out. If it doesn't, reverse back a little and it will. NEVER drive on non-slippy tarmac with difflock engaged - you will damage the 'box !!!
Good luck
Dave
cheers dave very usefull didnt know about diff loc at all when i get the bloody leaver to move i only select diff loc when stationery i take it,with the low ratio do i just firmly push the leaver forward im 16 stone big build guy dont want to rip the thing out the floor,or should it glide into place

nah most of them have never been used (Twots buying them and only using them on road) so it will need a good ram home

you can select the diff when you are moving, just as long as the wheels arn't spinning, EG one has grip, the other slipping. Its best to select it when you anticipate your going to loose traction, rather than when you actually have, because it means you will have to stop.

The advice in the owners manual is the best I think... it amounts to engage it when you think you're going to need it and disengage it as soon as you're sure you don't need it. Only experience will make sure you get it right.
You'll get properly stuck less if you have the difflock already engaged when you're going to need it, than if you get stuck without it engaged and try to rectify the situation by engaging it.
If you just leave it on all the time, the chances of breaking summat increase quite a bit

How to use the
TRANSFER GEARBOX. Copied from the Disco 1 user manual.
The second gearbox (known as the transfer
box) is used to select either the high or low
range of gears and, in addition, also controls
the central differential (known as the DIFF
LOCK).

High range (H)
The high range of gears should be used for all
normal road driving and also for off-road
driving across dry, level terrain.

Low range (L)
Use low range gears in any situation where
low speed manoeuvring is necessary, such as
reversing a trailer or negotiating a boulder
strewn river bed; also for more extreme
off-road conditions where progress in high
range cannot be maintained.

gearbox lever; the normal method -
recommended for inexperienced drivers - and
the advanced method for experienced
drivers.

Normal method
Manual models:
With the vehicle stationary and the engine
running, depress the clutch and then move
the lever fully forward (or backwards) in TWO
distinct but positive moves - high to
neutral.... neutral to low (or vice versa).
If there is resistance to the gear engaging, do
not force the lever. Instead, with the main
lever in gear, release the clutch momentarily
and then try again.

Automatic models:

and then move the automatic gearbox selector
to the N (neutral) position before moving the

Changing from high to low on the move:
With the vehicle slowing to a stop and
travelling NO FASTER THAN 5 km/h (3 mph),
depress the clutch and push the transfer lever
into neutral. Just before the road wheels stop
turning (and with the clutch still depressed)
push the lever fully forward into L (low).

THE DIFFERENTIAL LOCK
Unlike many four wheel drive vehicles, all
Land Rover products have permanent four
wheel drive. This is achieved by the inclusion
of a lockable differential between the front and
rear drive shafts. With the differential locked,
the drive shafts to front and rear axles are (in
effect) joined together, causing both to rotate
at the same speed. This is a normal feature
with all four wheel drive vehicles and
enhances traction on difficult off-road
surfaces. However, with the differential
unlocked the different running requirements
of the two axles can be accommodated,
thereby enabling Land Rover vehicles to
operate permanently in four wheel drive for
both road AND off-road use.

Selecting diff lock
The diff lock can be engaged or disengaged
either with the vehicle stationary, or when
driving at any road speed. However, with the
vehicle in motion it is ESSENTIAL to be
travelling on firm ground, in a straight line,
and without wheel slip.

WARNING
DO NOT engage the diff lock if one or more
wheels are slipping - this could damage the
transmission. If wheels are slipping, ease
off the accelerator before engaging the diff
lock.

When to use the diff lock

be locked in order to drive off-road on loose
and slippery surfaces. ALWAYS unlock the
differential for normal road driving or as soon
as a hard grippy surface is reached whether
high or low gears are selected.

WARNING
If the vehicle is driven on normal road
surfaces with the differential locked, the
steering will feel stiff, excessive tyre wear
will occur and the transmission will be
wound up putting excessive strain on the
transmission.

Diff lock warning light
The amber warning light on the instrument
panel illuminates when the diff lock is actually
engaged - rather than when it has been
selected. Similarly it will only extinguish when
the diff lock is actually disengaged. This
accounts for a slight delay between diff lock
deselection and the warning light
extinguishing, which is quite normal.

IMPORTANT INFORMATION
Transmission wind up
Transmission wind up
If the warning light is obviously reluctant
to extinguish after the diff lock has been
deselected, some transmission wind up
may be present.
Reversing the vehicle for a short distance
and then going forward will usually
unwind the transmission and extinguish
the light and the vehicle can then be
driven as normal. However, if after two or
three attempts to unwind the
transmission the light remains on,
consult your dealer AS SOON AS
POSSIBLE.

Hi newbie, As u don't have an owner's handbook, go the the link below. Click Discovery - Owner's handbooks - Continiue and then take your pick of four for the disco1.. If 'pop-up' is blocked on your computer then you will need 'pop-up' to be enabled to open the handbook PDF file and then save.

High box is best in most circumstances when traction is sparse...
