Hi I have a 1986 Landcruiser, which has got me from the UK down to the central sahara and back without missing a beat, but on long runs has a tendancy to somehow draw gear oil from the transfer box into the gearbox. This results in the gearbox being overfilled, the first indication of which is the clutch starting to judder. (i assume an overfilled gearbox starts dumping oil into the clutch casing somehow).
There is a need to drain the gearbox every 5000 miles or so, plus of course top up the transfer box with a couple of litres.
Any ideas on how to stop this problem????
Cheers... Chris
