So good news, i had this fixed, sadly i could not do it myself as i am now away working and also do not have a hydraulic lift to get the car to a suitable height... I was charged around 500 quid in total by the jag specialist to have a new pan fitted and all that transmission fluid that is required, its like driving a cloud again and no leak to mess up the drive great service from the garage too, they only had it for a few days and even sent me video updates, picked it up and dropped it off, they pointed out couple of other issues i have but didn't try to force me to have them done which is a refreshing change, i will fix them when i get back
