My 6.9 is largely "oil drip free" on the garage floor with the exception of a 5 cent piece sized drip of red Automatic trans fluid which appears during it's 5 to 7 day lay-over between drives.
The automatic was serviced last year by "The Star Shop" in Perth with a filter and fluid change.
Recently it spent 2 weeks sitting on my hoist while I was waiting for some suspension parts to arrive and while it was sitting there it dripped about 10mls of automatic fluid onto the floor.
On the hoist the car was sitting in a "Bum-down" attitude as opposed to the more normal "Bum sightly up in the air" position it normally runs and settles into after a few days.
Since returning the car to it's wheels the floor has remained totally clean with no drips whatsoever.
On careful inspection the oil seemed to be coming from the right rear of the auto and the vacuum modulator had some oil dripping from it (?Around it). It did not appear to be leaking from the pan gasket area and the torque (7nm) on the pan bolts was correct. Rear seal is dry as is the torque converter.
I have not done a hot fluid level check to make sure it is not overfilled and automatics are the one part of a car that are largely left well alone by me but I have heard somewhere that a vacuum modulator can fail and cause a fluid leak or worse - allow oil to be sucked into the engine unnoticed.
I would imagine if they fail to this extent that it would cause the shift quality to become rough - which is definitely not the case.
Opinions would be gratefully accepted.
