The next morning I decided to call the RAA to see if I could get my car to a garage to have its gearbox filled up with fluid. My car was transported to the nearest RAA approved garage which was in Copley. As it was Sunday, the RAA kindly put my up in the Copley Caravan park. This is a fantastic place. If you have the chance to stay there I would certainly recommend it.
Early the next morning, the mechanic turned up at the garage and he changed the fluid in my gearbox. I returned to Adelaide the same day, slightly sad that the adventure that had been been planned for well over a year was at an end. It was a great trip with fantastic company.
I would love to cross the desert again. Maybe next time by one of the more remote and lesser used tracks.
