Hello when changing the tires on stage discovered that the Twingo 2 Facelift is leaking from my wife at the transmission. There oil runs out and that is below where the Simmerring is. First a friend told me it would be quickly repairable and then my father-in-law told me it was not so easy. What’s right now? I read that there is a repair kit but that I had seen for the first Twingo. Can one help me further. It’s the 1.2 engine greeting Torsten
