My first post on the forum,I,ve been an avid reader of others problems and thought ha I have none. Untill now,my 2004 4.2 v8 auto has come up with display showing gear box fault.This happened about a month ago,my heart sank.Pulled over and stopped turned it off then restarted it selecting the sport option.Problem went away and has gone until TODAY.Same message only has stayed and previous trick did,nt work.It feels like a manual box with slipping clutch.Plenty of revs and it picks up speed,but drinks fuel.Any one any ideas PLEASE.
