Holden began assembling the compact HA series Vauxhall Viva in 1964. This was superseded by the Holden Torana in 1967, a development of the Viva ending Vauxhall production in Australia. Holden offered the LC, a Torana with new styling, in 1969 with the availability of Holden's six-cylinder engine. In the development days, the six-cylinder Torana was reserved for motor racing, but research had shown a business case existed for such a model. The LC Torana was the first application of Holden's new three-speed Tri-Matic automatic transmission. This was the result of Holden's A$16.5 million transformation of the Woodville, South Australia, factory for its production.
