A stupid mechanic somewhere in Onne did a bad job and damaged my car gear box. He was supposed to discharge and gearbox oil and replace it with a new one, which he did without following the normal procedure. After a few kilometres away from his workshop the car refused to select from gear one to two. Now d gear box has bn damaged and someone told me it can hardly be fixed. Pls who has an idea on how much the toks will cost me?
