no its only when braking i dont feel it through the steering or brake pedal but more through the whole car i was wondering if it could be a engine or gearbox mounting as the gear lever moves in time with the judder?

i have this problem with my 940 1993 iv changed the brake discs and its still the same its not a violent judder more like a surge and ive noticed that the gear lever (auto) is moving back and forth in time to the judder any clues what it might be?
