Hi all
I will be changing the gearbox fluid if i remove the drain plug will this empty all the fluid and from the oil
cooler

[Phil Nottingham]

Not not unless one of the unions is undone as it will be held by vaccum. It may release if its left standing for several days as like the fluid in the torque converter also, it takes this time to drop below the centre line. Its impossible to fully drain the converter without removing it!

Having a problem
Engine rebuilt and gearbox had new pan gasket and front and rear oil seals repalced
Left grill and rad off as i am doing other work on it at the moment
Not a drop of oil in the 8 weeks it sat there untill last week
There seems to be gearbox oil on the floor from the oil cooler pipes
Cant see how as it aint been started or moved in 8 weeks?
But i remembered a post a while back about this happening to some one but cant find it

You migth be referring to an entry I made way down in a posting under "gearbox leaking" . I had a leak that meant that the car could stand for quite some time and the suddenly spill a fair amount of oil. And then it could stand again for a while and the spill again..
-
I took off the pan and replaced the gasket and I also replaced the small seal at the selector-arm. This little seal was very difficult to reinstall with the box in situ, so take care.
In the P6 workshop manual there is a notice that leaks at that little seal is common, and it will appear as though the pan-gasket is leaking because the fluid will sipple down to the pan.

Mine seems to have stopped leaking after these corrections...
