A three speed automatic transmission made for various Holden vehicles from 1970 through to 1988 such as the Torana, Kingswood and Camira. It was replaced by various GM units. Often endeared "Trimagic" for its fluid, smooth shifts, or "Traumatic" for its dire reliability record, the copious amount of power it robbed from the engine, and the overwhelming amount of oil it left on your driveway. Operation is by a column shift or floor shift.
