2017 Holden Commodore Pricing and Specs

An automatic gearbox relies on fluid pressure as well as volume to make everything work as it should. So, if the level of fluid is correct, you then need to move on to the pump and accumulators involved to ensure that the correct hydraulic pressure is being applied to the bands and clutches that actually apply drive to the gears and physically move the car.

Your problem could be something as simple as a worn pump, but it could also indicate internal wear and tear that requires a complete transmission rebuild. A transmission specialist is your best bet. The good news is that this is a common and well understood transmission, so finding an expert shouldn’t be difficult.

Let’s start with what made a 2017 Holden Commodore an SV6. Over and above the standard Commodore specification, ordering an SV6 also got you the higher-spec V6 engine with 210kW, 18-inch alloy wheels, FE2 (firmer) suspension, LED daytime running lights, a leather-wrapped steering wheel and a body kit.

The Black Edition package, meanwhile, was a visual enhancement package that could be specified with either a Commodore SV6 or SS (the V8 model) and, in the case of the SV6, added specific black alloy wheels (still 18 inches) a blacked-out grille, black rear lip spoiler, Black Edition badging, satellite navigation, an improved info-screen, red stitching on the seats and specific floor mats.

These late Commodores (the very last of the locally-made Commodores, actually) do, in fact, have a history of fuel injector problems. Holden has claimed that poor quality fuel is the cause, but some technicians disagree, arguing that it’s a problem inherent in the injector’s design. Some owners have been told that it’s better to run these cars on 95 or 98-octane fuel, even though the LS3 V8 is rated to run on 91-octane ULP. But it seems even cars that have been run on the pricier brew are still recording problems with the injectors.

The faulty injectors send the engine into a potential lean-mixture situation, at which point the on-board computer intervenes and sends the car into limp-home mode to avoid engine damage. That’s why you’re seeing all those warning lights on the dashboard, while the injectors themselves are what’s causing the rough running you’ve reported.

There’s been no recall on Holden’s part, but the word on the street is that a Holden dealer will replace the injectors free of charge if you present the car at the dealership with the symptoms in evidence. Holden’s announcement that it will cease to trade in Australia should not affect this situation.
