I've noticed that if I baby the car and keep the revs down, it doesn't leak...or if it does, it's a single drop or so. If I really get on her, shifting hard and maxing rpms in the first three gears, it will leak like crazy...straight away when I put her in the garage as a matter of fact.

The dealer is replacing every part bit by bit until it stops leaking...fine by me but it'd be nice if they would actually diagnose the problem instead of just attending to the symptoms every time.

Anyone have any ideas what this might be? I've been told that it's possibly a clogged pressure relief valve which would explain the rear seal burping under higher pressure and not the low revs. Then again, this may be completely false.

I really don't want to be going through this for another month...it's hard enough as it is not being able to really drive her as intended.
