No, there are no oil leaks, the strong shake happens only in the first one, to get out without shaking the car, I have to keep the clutch at 1/3 of the total stroke until it develops a speed of + or - 30km / h and then release the clutch, the strange thing is that when they check it, they disassemble it and replace it without finding anything new, the clutch works well for 30 minutes and then starts with the shake.
