Who knows the susceptible A604 transmission closer? My converter bridge opens up somehow too late, when switching up without kickdown – so easy acceleration he then often blows in with force the next gear and when braking at the traffic light he pushes even further, so that you have to brake more. Had even almost strangled the engine, but then he caught up again and opened the lockup. Unfortunately I don’t know exactly where to look…. ydraulik/Ventile? Gear oil and filters are already new, oil level also fits, old oil was a bit darker but ok.
