Our 2002 VX Commodore wagon has done 128,000 km, but doesn't do any towing. What is the recommended time frame for having the automatic gearbox serviced and to what extend should the service be?
There is no Holden recommendation, as far as the company is concerned the transmission has been filled for life in the factory and needs no further servicing. The trade has a different view, however, and generally recommends an oil change service every year, and a major service, which would flush the transmission every two years. There’s no hard and fast rule, it comes down to common sense. In your case, at least get the oil and filter changed.
