LC LJ LH LX and UC Torana Repair Manual
The Holden UC Torana (1978–1980) was the final Torana ever produced and represented Holden’s transition toward emissions compliance, improved comfort, and the coming Commodore era. While it no longer offered a factory V8, the UC introduced refined six-cylinder drivetrains, improved braking, and modernised interiors, making it a very usable classic today.
Restoring a UC Torana correctly means understanding UC-only parts, ADR changes, and differences from earlier LH/LX models — especially around engines, brakes, and trim.
