Wife got in her '06 LR3 tonight (72,600 miles). Won't shift until she hits 6-7000 rpms, for every shift, and than VERY rough shift. Same thing in sport mode, but manually shifting works fine. No problems leading up to this. Getting a "No DSC fault available" immediately after starting. Any suggestions??? Hoping the tranny isn't going ka-put ...

Drove it to work this morning - roughly 30 miles one way. Cruise Control wasn't working and about half way I got a "transmission failure" and a "HDC not available" message. Ironically, drove it home and everything worked normally. No messages, shifted like nothing ever happened, and cruise control worked perfectly. I'm confused?!?
You know I'm certainly no expert at electronic gremlins, but a weak battery can throw dsc and hdc faults. I suppose it could be possible that if your battery is original, that could be part of the problem. And it doesnt necessarily have to 'feel' weak to be a little below whats needed. Although I've not heard of weak batteries causing shifting problems....
Brake light bulbs, brake switch etc
Check your brake light bulbs and tail light bulbs - have you changed any recently and put in non Land Rover brand bulbs? Brake light circuit problems can show up as tranny not good, plus HDC and Cruise not available etc.
When everything is wrong, the problem is generally minor - just the computer system making a big thing out a small problem.
Replace your brake light switch - about $25 and if that not resolves the current problem, then it will stave off another one that will show in time.

get it diagnosed properly. pull the codes and go from there. dont beat around the bush
Craziness! Took to Dealer. They said battery was the culprit. Replaced it and said LR3 was as good as new. Drove home and everything was fine. Left a little while later and initial problem reoccurred. Took back to Dealer following day. Kept it a few days. They called me and said they did some reprogramming and that everything was fixed. Wife picked it up that night. got a little over a mile down the road and initial problem re-occurred again. Right back to the Dealer! Called me yesterday and said they finally have it fixed. Apparently they replaced the driver side Brake Lamp and now everything is running as it should. Does this sound absurd to anyone? Ridiculous!!!
Not absurd, just annoying.
I guess that is why I posted about brake light filaments and make a big deal about it.
The link below is to a number of files I have in my gallery on disco3 re the brake light circuit, bulb filaments, and the brake light switch.
There is a brake circuit pdf also and if you really examine it with a microscope, you will see how merely stepping on the brake pedal, (or not), sends signals, (good or bad), to the ABS module, the Transmission Control Module, Hill Descent brains or lack of, and who knows what else as the CAN Bus is informed as well.
The reason this sort of thing does not happen on most normal vehicles is that normal vehicles do not have any sort of Hill Decent Inhibitor. Believe it or not, when the hill descent is retarding the vehicle, the brake lights go on even though you have not touched the brake pedal.
When brake light filaments are not as they should be, the computers pick this up as any number of problems. Dealers have installed brand new automatic transmissions due to owners installing non Land Rover supplied bulbs and hence the problem remains. When the dealer discovers the non OEM bulb, you are paying for the new tranny or you do not get your 3 back.
Also you may as well get a new brake light switch installed as if it not already going bad, it will. I also have a suspicion that a defective backup light can result in similar problems.
