change the radiator for a new one, anything will do, the bottom 8 rows collapse and the auto oil cooler temp levels get very high, whatever you do don't buy a Land Rover radiator ( as the same thing will happen again in 10 years time )

then flush all the auto oil with Mobil Esso LT71141 ATF Automatic Transmission Fluid BMW Audi VW, it should cost about £6 a litre, not cheap, and you will need 8 or 9 litres to carefully flush out all the old, chances are someone has been topping up the ATF ( Auto Fluid ) with the wrong type (probably cheap DEXTRON) , this is not helpful in the least, as apparently the auto is very fussy on our cars 4.4 BMW Auto


and change the auto gearbox oil cooler for a new - they are £49

Don't waste money on another battery, buy an IID tool and start checking things out, go through the live values and see what you can find...

There are several reasons yours could be doing this, you have listed most of them...

Check voltage, xyz, temp and read and decipher all the fault codes that will come up...

It will cost you a fortune if you take it to a garage, they will just replace bits until they get lucky... seen it happen lots of times... Pete

Sorry for the long message! Any ideas welcome and also any RR independents that are around GL56 or a reasonable drive away would be happy to talk to you!

Hi all, am going to CMS on the 15th to have codes checked and transmission fluid replaced and sump off and check for any metal filings in the oil etc. Fingers crossed this will be the solution I need and not a gearbox!

If it all goes wrong (hopefully it won’t) you could do a lot worse than contacting these chaps

Hi there, sorry for the delay - after numerous calls and different advice and almost selling it I decided to start simple. Luckily I have a great local garage that look after me and my various cars and are usually willing to give most things a go that I throw at them! Started by doing the transmission fluid change and checking for any shavings - fortunately there was little debris stuck to the magnets and everything looked good - no more than you would expect on a regular change. The transmission fluid was lower than it should have been so a necessary job done. Started the car once that was complete and still getting the same problem. Mechanic agreed that it seemed to be electrical rather than mechanical / gearbox failing. He also had the gut feeling I had about the xyz switch and got quotes for recon units. I asked him if he would be happy to drill out the rivets on the existing one and have a look inside and clean it up if necessary and adjust the contacts if they looked like they needed it. He was happy to give it a go and there was a build up of muck inside and the contacts were worn and not making clean contact so he adjusted them. Had it dropped back today and excitedly jumped in and put the key in - straight away ping and transmission failsafe message.... thought great what a waste of time and money. I then took the key out, back in and boom 💥 it started! Took it for a drive, smooth gear change and pick up through all gears and had 0 troubles which is not something I have had for months. Thinking it was certainly not the gearbox that was shot as the local independent Land Rover garage said with a £3k quote to fix.... I think the failsafe message may just be a warning that the xyz has been fiddled with so may not be perfectly adjust but at least I can drive and have a smile back on my face!

Thanks to everyone for their input!!

very good news to hear, well done - and saved £390 quid if you had to get a new one

The XYZ (sensor) is in a spot renowned for letting in water/grime/dirt - so after a good clean I guess you are golden

I see mine was replaced 3 years ago - and I had since forgotten about it - they are crazy money to buy new

SKU UHB500020

An OEM replacement gear position sensor switch. Commonly known as the XYZ switch. This sensor/switch tells the ECU which gear the automatic gearbox is in. It is fitted to the side of the gearbox and often lets water in causing a malfunction.

By coincidence, my 2004 V8 is at Birch Motors with the same symptoms as Smather’s Range Rover. I’ll report back on this thread to let you know what Birch find.
All the best

Birch are a lot more focussed on L322's and BMW X5 gearboxes thats for sure

my local Indy in Hemel Hempstead is more than twice the price approaching £2500

so after getting a PM from Phil that he has no more reconditioned boxes in his garage, I'm off to Stephens Engineering in Ware for a gearbox service and see what happens ( they are on the A10 near Hanbury Golf Club ) , so I'm gonna play 18 holes with my brother and collect the car at 5pm
