Its a mystery....

["Paul Audemars" <Footwearfindings@domain.elided>]

The (auto) gearbox of my (71) stag leaks fluid.

It's been checked twice by the (very competent) people who regularly look
after the car and twice in the last 12 months by the (extremely competent)
gearbox specialists who installed it for the previous owner.

The gasket has been replaced... a LOT.
The sump nuts are checked and tightened specially every service and have
non slip washers on them.  

The banjo bolt/washers on the dipstick assembly have been replaced -
allegedly unnecessarily.  
All seams and joins have been checked.

The thing is, it only does it when the car has been standing for a week or
more.  
If the car is in regular daily use or on a run or a holiday, there is
absolutely no problem.

Any ideas?
