Australian law firm Maurice Blackburn has filed a class action lawsuit against GM for faulty transmission systems in certain Holden models. It applies to the 6L45, 6L50, and 6L80 transmissions in vehicles purchased between January 1st, 2011, and December 24th, 2024.
“The class action alleges that General Motors failed to comply with the guarantee of acceptable quality under the Australian Consumer Law and engaged in misleading and deceptive conduct,” the law firm said.

The alleged problem with the affected transmissions is a defective design in the torque converter and torque converter clutch. Problematic transmissions cause intermittent shudders, excessive vibrations, hard shifts, fluid leaks, accelerated degradation, and greater servicing requirements.
“The class action seeks to recover compensation for loss and damage on behalf of consumers who acquired the affected vehicles,” according to the law firm.

Holden was a mid-19th-century saddle-making business that moved into automobiles in 1898. About three decades later, it was acquired by GM in 1931. A small domestic automotive market and competitive pressure from cheaper imported cars eventually eroded Holden’s viability, leading to it ending production of its last model in 2017 and The General retiring the brand in 2020 to 2021.

The 6L80 in my 09 G8 GT was great over the 15 years that I had it. I wasn’t always easy on it either. At least in my example, I think that these transmissions were built stateside and exported to Australia. If that was still the case in these later units, the same risks would be present in US/Canadian applications, wouldn’t they?
It is a known issue in the US as well. Last I knew, a combo of flash update and change of transmission fluid type to a new Mobil product was able to “Fix” the majority of the issues with the 6 speeds.
No recall or bullitin issued?
Or “bulletin”
Just like the 8spd here but gm must have paid off the governing body for any recourse here. I hope they win down under. It’s the only way gm will acknowledge to a defective product. I am a lifelong gm buyer but will definitely looking at the competition for my next new suv/car.
GM does not stand behind there products. Last time I will buy a GM car. 2014-2019 eight speed transmissions have major problems.
we have 2017 Holden Trailblazer. we have had faulty transmission as well. have ordered part . hope here soon .
