Auto gearbox not engaging

Any ideas or experiences please? About 6 times this afternoon, sitting at traffic lights, box in neutral, change into drive and no go - engine just reved. Back to park then drive to get it to go. Also at two junctions braking from 30 in drive to turn right the car changed down but then left me in neutral, requiring a change into park then back to drive.
Dealer will get a visit on Monday, but I'd like some thoughts.

I'm only making a comparison - it may be relevant or it might not (but here it is anyway)...I'm sure one of the technical genii will enlighten us...

Disco II's had a "get you home mode" that when engaged (for a whole bunch of reasons - mine was defective in tank fuel pump) it had the same effect - no drive, even though car in "drive" engine running etc. The engine runs at tick over speed & the accelerator pedal depression has no effect.
The impression I got was the the accelerator pedal felt somehow "empty" & if pressed didnt raise the engine revs. On the Disco II no warning light for this

As with you fault the fault came & went - very embarrassing at traffic lights as there is begger all you can do...
I actually got used to it on motorways - which was a bit of an accomplishment - my Disco II (the first one I had about 2001 vintage) was on a journey from Bath (the place - not the bathroom fitting) to Halifax.

The Halifax dealer had trouble getting it from the car park into the workshop !!

I will watch the thread....in my case the get you home mode was over 300 miles
It would be good to know if the get you home mode/s actually have a warning message flag up on the display

Hope you get it sorted
Good Luck !

Donald, my auto has just started to behave similar. IIRC I saw a thread about this a while back and there is I believe a TSB for it - just can not find the post. When mine does it if I move the auto lever slightly it engages properly. I'll have the dealer have a look at it when it goes in for its next service (got a 30 day countdown message today).

I have not had it change into neutral whilst driving yet Surprised does that and it will have to go into the dealers a bit sooner Rolling Eyes

I think its a simple cable adjustment.

Selector cable needs adjustment. There is a TSB that covers this, but blowed if I can remember the details. Your dealer will know and LRA are able to make a fix the selector at the roadside if you get stuck.
 I know it's not considered "kind" to say no these days, but no. Just no, ok? And if it's not ok, still no.

Sounds like a possible selector cable adjustment problem to me, but unusual if it has only just started to occur today, I would think it would have shown gradual evidence over a longer period. Have you had any brake light filament problems recently? because faults with these can make the auto box do some wierd things. I haven't tried this recently so forgive me if I'm wrong, but if you drive the car normally in drive and dab your other foot (lightly) on the brake while accelerating, you will probably find it won't change up and you'll get a fault message up, having dodgy(not necessarily blown) brake light bulbs, or inferior quality bulbs, can cause odd things to happen without any input from you, other than driving it as you would.

I've had quite a few break light bulbs blow lately Evil or Very Mad The passenger side twice (last time about 6 months ago) and then the drivers side about 5 times all within days of the new replacement bulb being fitted. Last time it went, the car was due in at the dealer anyway so told them what was happening, they told me that there is a known problem with the brake light switch causing the bulbs to overheat and then blow. Their instructions from Land Rover were to replace both break light bulbs (with genuine LR replacment bulbs), depending on how long they last and if they look like they had overheated they could then replace the switch (think thats what I was told)

OK I take the possibility of the selector cable being out of kilter as being the most likely one - but agree it would have other effects & a question is the setting so critical that a smidgeon out will cause loss of drive ?

The mention of brake light globe filaments having an effect.....I have to ask why this would get to the control of the box & make it lose power transmission...when you think how an auto is driven i.e. you swap from the accelerator to the brake pedal at will as part of normal driving.
If a dodgy brake light globe is there when you actually brake it means the light will either not come on at all or intermittently come on much the same as pressing the brake pedal on & off quickly.
If the globe filaments are so critical - what is the effect of fitting LED bulbs? which I would like to do but am cautious if this may have knock on effects.
As the Disco doesn't have bulb failure warnings (or does it) I wouldn't have thought this relevant at all..

The test of pressing the brake pedal whilst accelerating may invoke other systems...it should "load" the vehicle & cause the box to change down (or at least it does on a not so electronic auto from some years ago). I will try this on my OK Disco 3 & will report back as to what actually happens

I'm really interested in this the outcome of this thread / fault as in the past I have had to adjust the auto selector linkage on my first Disco II (& other vehicles mainly Volvos with Borg Warner & Aisin Warner boxes)

Hi Bruce, (still don't know if that's your real name Smile )

If I remember correctly, faulty or blown brake lights (amongst a million or so other things) can cause havoc with the D3's electronics, causing the car to put itself into limp home mode, often dropping the car onto its bump stops and messing about with the auto box too. (I think this is flagged to the driver via the message centre in the instrument cluster)

This is probably what DND was talking about, although my money is on the selector cable being out of adjustment too - the actual movement/difference between each 'gear' is very small when selected from the bottom part of the gearlever, so yes....a small error and you would probably give these symptoms easily....

Oh and BL Farrar, if you're out testing your car,I meant LIGHTLY on the brake pedal, not enough to load the gearbox...........The chap was asking for ideas, as I said, the most likely thing is selector cable out of adjustment, but I thought I'd mention the other things too, as I believe they may be relevant, but I agree that it should not cause the box to drop into neutral of it's own accord.

Left foot braking on an 07 MY manual brings up the message " Engine fault " or similar. Bit of a bummer when I regularly do this, especially after a bit of Fording !

How does a brake light blown or dodgy filament cause issue with the gearbox ??

The wiring so poor that electrical interference from a dodgy bulb can cause a completely different system to fail or misbehave ?

Not saying it isn't the cause, but just very intrigued as to how this could happen.

I'm no expert Si, but I suppose the g/box ecu receives / sends signals from / to umpteen other components,and if it sees a fault or improper input from the brake syst, it may well cause the g/box to misbehave, it's a D3, it does as it likes. Laughing.......I've no doubt TFC will give a much more knowledgeable explanation.
