Transmission problem in secondhand Cruze

You're on difficult ground having bought the car secondhand. If you'd bought it new you would be well entitled to expect it to be repaired by Holden free of charge. Unfortunately, being secondhand, the normal warranties don't apply and you're effectively on your own. Still, I would persist with getting Holden to come to the party with at least part of the cost of repairs. After all, it is a known problem that has affected lots of Cruzes.
