Hi Guys

Yesterday I wrote the following post and today i managed to go to the shop.
Transmission fluid overfilled S500 2000

The guy at the shop put the car on the lift and ask me to wait at the lobby. 20 minutes later he came in and called me to the bay and showed that the oil is leaking from the oil seal ( which I can't see and was told that it is located between the engine and transmission). Also told me that if I want to repair it is require to pull the transmission out ($$$$$). Is it possible? the car have 70,000 miles on it. It was not leak any single drop before i asked them to change the transmission oil. It is dripping 2-4 drops a day. He told me that eventually it will stop dripping. Please help with your advises.
