Hello! The data from my car: Audi 100 C3 Limusine Built 01/1986 101KW/137PS 5-cylinder, 2226 cc Mutor letter: KU (no KAT, K-Jetronic) The automatic transmission worries me. Years ago, I actually heard the sound for the first time, and that’s when I switched up to the 2nd gear. I would say that one hears such a metallic “rubbing” as if something slipped. Not very loud, but it sounds bad, comparable to a broken bearing or something like that. it is also heard manchaml, when you are driving underboard in the second stage and then there is no kickdown gas. You never hear it at full throttle, so when it switches from the first to the second stage it is nothing. Or when you kick down from the 3rd to the 2nd (overtake) is nothing. My first suspicion was that the brake bands are emptied out and slip through. But what I don’t think speaks of it: 1. If you hear slipping brake bands, you would have to hear them during every switching process. n. 2. If they slip at low speeds, they would have to do it at full throttle, because the torque is higher. Oh yes, that’s a change gear and doesn’t even have 150,000 km on it. Does anyone have something like that already, or at least an idea what that could be? If it’s the brake belts, someone has a guide on how to change it? And where do you get it?
