QuestionI own a Disco II 2000. I use it mainly to do expedition in North and remote places (Yukon, Alaska, Labrador). Good car with the traditonal Rover flaws. Since 2 years transmission is a pain in the.... Various rebuilt and the last one at the Yukon border. Then back to the Québec in 3 days without troubles. Previously, transmission temperature gauge was flashing, typically in mountainous situations, with load. Many others cars don't seems so picky, but I can understand.
I haven't use the Disco a lot this winter and it's time to prepare a new travel (North of James Bay is this summer target). And you know what? Transmission temperature gauge is warning, after 30 mns of driving, witout any provocation (steady pace, midly summer, no load). After a 15ms rest, all is correct but overheating warning light up in 5 mns again!
So I had checked: level and quality of transmission fluid: all is OK. I had checked the handbrake: it's not jammed. I had checked too the transmission fluid radiator: it's not clogged.
Land Rover dealer tell me the only way to fix this is to replace all the transmission. Big deal! My one is freshly rebuilt (4000kms) and this pesky overheating warning seems to be the only trouble.
Can you give me any advice ?

AnswerHearing your story, I would recommend using an infrared thermometer to determine the actual temperature of the gearbox and oil. If it's not hot, you have a switch problem. But if it is hot, I recommend a genuine LR exchange gearbox. Field rebuilds don't work out a lot of the time.
