Transmission oil leak

F10 550... It seem like im leaking transmission oil after a long drive and the car is turned off. Short drives there is no leaking but long drives with stop and traffic there is a leak. The oil is clear. Anyone else have this issue?

Sounds like you need to replace the trans pan (gasket and filter are all integrated to the pan). At that point you'd also be doing a drain and fill (not full flush). It will take a little under 4 bottles to fill back up to level per fill instructions.
