Hello. Just a quick piece of advice or your recommendations?. I recently bought a 04 Td6 Range Rover with 110 thousand miles on the clock. I am wondering as to whether I should take a preventative measure and change the oil in the transmission??. Thus preventing any future problems with the transmission unit. If so which oil should be used?. The transmission is fine at the moment and Land Rover tell me that there is no need to change the oil as it is a life time seal?. What is your advice?. I have a friend who specializes in transmissions and he advises me to change the oil?. Thanks in advance!
