For the last months I found some small drops of oil under te car. I suspected the rubber gasket behind the engine oil cooler. Today started to work on it. After removing the engine under shields it was obvious that the lower connection of the transmission cooler was leaking. First thought was that the hose was a bit loose but after a bit of fiddling with it the tube broke of completely.
To be clear: this is not the radiator/transmission cross contamination issue. I've bypassed the radiator.
mmh, found a spare at a salvage yard. For once parts of the diesel cars are interchangeable!

The car has now 168k km. Is this normal? I haven't heard of this issue before. I've been lucky it didn't rupture while driving, that would have been fatal to the transmission.
