Anybody know what this message could be...? its went on and then I re started the car about 2 hours later and with over half an hour of drivin it didnt come on... then in the morning the Transmission fault message came on again........ Any ideas.....?[b][/b]

Transmission fault = Go to dealer My Gladiators:

RRS S/C HST - respect of the highest order
Freeloader 2 SE with all the toys - my baby RR
Merc SL55 AMG - Tarmac ripper!

Disco3 - Gone
Defender 90 TD - Gone
FFRR Vogue - Gone
BMW X5 4.4 - Gone
LR Defender 300Tdi - Gone
LR Defender 2.5 PETROL - Gone

It may also be a low battery condition, especially if the error messages - you may get more of them if that's the case, such as HDC fault, suspensions inactive, etc. - appear only at startup and then clear themselves. 

Battery.......
- Get a new one.

Especially if it happens on a cold morning. The you start it, charge the battery, and all is well, until the next cold day. It's not cold in Ireland though....

Or, there could be a transmission fault....  Range Rover Sport SC - Java / Tasmods / Skirts

i have exactly the same problem with my tdv8. i have called out lr hinderasnce and was told nothing wrong with battery.
car went back to dealer, explained fault to chap who collected it, but the blank expression said it all, needless to say, car came back with the stealer saying nothing wrong with it. i did explain it need to be kept over night as the problem occured in the morning, again, blank exspression!
any suggestions how i can get the stealer to re-think and resolve? other than calling land rover and complaining, again.

Daily calls to LRA should get a response eventually

Take it to another dealer? If it's easily reproducible then someone just needs to pay attention to what you say  

I had all my sensors changed out, then I suggested the battery,
- Worked a treat.

I suppose you could solve it with a battery conditioner. If you use one overnight, you shouldn't get the fault in the morning. Try Accumate.

Or go to the dealer, run the battery down by switching lights radio etc all on for a while. Then start her up and you should get the same fault.  Range Rover Sport SC - Java / Tasmods / Skirts

A dodgy battery can cause all sorts of apparently unrelated issues... MDPs car was a good example of that  

thanks for nthe comments and advice, i will try another dealer and see if i get any joy there.
