Apparently, I have just broken the primary pump in the transmission of my E 500...
It happened as I was driving at about 50 mph without pushing the car. The transmission suddenly started doing a whining noise when accelerating but only until something like 2500 rpm ; it has lost some oil but the oil left is of the right color.
Trans is only 12000 miles old, OEM and fitted by MB. The car is at the MB dealer shop.
Any idea, suggestion, bad news ?
