Took the car out for a run yesterday, have not been driving it much this winter, less than 300 kilometers since october. Found the trans slipping a bit in higher gears, clutch feels a bit different, engages real late when releasing pedal. Car only has 63000 miles on it, not noises or sounds, running well other wise. Any thoughts on what problem is, could it be a fluid problem or actual clutch problem. Going to try to bleed system today, no drips anywhere. My other 528e had 300,000 km and wtill original clutch. Current car is a 1986 528e, also, anyone out there have any suggestions for upgrades if I do end up needing a clutch.
