When GMH fitted the six cylinder engine to the LC Torana, it was logical to also allow the all Aussie Trimatic auto transmission to follow suit. As for the manual transmission, the GM engineers knew the clutch from the four-cylinder Torana would be ill-equipped to handle the torque of the sixes, so they instead fitted a larger diameter 8.62 inch version (instead of the regular 6.25 inch version), with a heavier plate Belleville design diaphragm spring unit.

The suspension system used on all LC Torana's was basically the same as on previous models, although spring and damper rates were revised for the six cylinder versions, and the mounting points were naturally different. In addition to higher rated springs and shocks the six cylinder Torana's were equipped with plenty of rubber bushings to enhance ride quality and isolate road noise.

The rear suspension on all models remained a coil sprung design utilising four links, the two outer links being mounted directly on the coils and the inners were diagonal. Only the GTR scored a rear sway bar, and was the only model blessed with front disc brakes - although they could be optioned on all the other models. Because the fours ad tiny 12 inch wheels they simply couldn't take the 10 inch discs available on the sixes, and instead they got 8.4 inch units.

The wheel and tyre combinations were far from great, particularly by today's standards. The 13 inch wheels on the sixes were very narrow at 4.5 inches, as only the GTR got 5.5 inchers. The four cylinder Torana's had a misely 4 inch wide wheel to deal with. Worse still were the standard fare tyres, even the GTR not benefitting from radials, instead getting B70H x 13 red band crossplies.

Apart from the engine size and extra length, there were only a few other minor points that differentiated the fours from the sixes. The fuel tank was increased in size from eight to ten gallons, and the six cylinder engines were also fitted with a new type of pre-engagement starter motor.

Today the LC Torana is a highly sought after model, the "W-Style" frontal treatment looking as good today as it did back in 1969.
