@ Dave2811 : I did understand that you ment the gearbox oil. I've been working in a workshop where the Pantera is the only old car. The rest are modern cars like Porsches, Astons, Vipers etc. The oil they use for these modern engines is as thin as water so I changed it after ons session. Maybe the oil they used for the gearbox is just as thin and that might be the problem. Only, I can't find out right now because the owner of the shop is on a holiday for 11 days so I don't have acces to the car.
I'll keep you posted.
