just bought a 2000 disco off craigslist and bought it, crawled under it to see the front end drenched in oil or trans (i knew about this when i purchased it) and the guy told me he used to work at a land rover dealer and did all the needed work for it (have all paper work) and he tells me its leaking from a hose that goes from the trans to the radiator or something, and says when it gets cold a o-ring or something lets a bit of fluid out, im clueless at this point! can someone help me or give me trouble shooting or places to check? and whats this o-ring? someone help me thanks!!
