Hi, 
 
	David Evans off the Facebook Group.
 
	If the pic was from the back of the car I am sure that broken rubber concertina part is the handbrake cable gaitor!
 
	When was the autobox last calibrated? A long time since my two selespeeds but I imagine they re not that different but it made a big difference.
 
	No sure on the knock, could be anything suspension or steering related.
 
	Low oil pressure could also be from using the wrong oil or from a faulty sensor.
 
	There is AutoLusso in Bournemouth or Rusper Alfa near Haywards Heath who are Alfa specialists and will know the autobox as it is the same a Giulietta. Also Sussex Alfa in BN6. which may be nearer.
