    Holden Transmission Class Action

    Maurice Blackburn, with support from litigation funder, Balance Legal Capital, is conducting a class action against General Motors Australia and New Zealand Pty Ltd in the Federal Court of Australia in relation to faulty transmission systems in certain Holden Vehicles. 

    What is the Holden Transmission Class Action about?

    The Holden Transmission Class Action has been brought on behalf of people who acquired certain models of Holden vehicles between 1 January 2011 and 24 December 2024, equipped with a:

    • GM 6L 45 transmission;
    • GM 6L 50 transmission; or
    • GM 6L 80 transmission. 

    The action alleges that the transmission systems in the affected Holden vehicles are defective due to a design fault in the Torque Converter and Torque Converter Clutch. As a result of the alleged defect, the affected vehicles have a propensity to experience various problems including intermittent transmission shudders, excessive vibrations, harsh gear shifts, leakage of Automatic Transmission fluid, accelerated degradation of the components of the transmission system and greater servicing requirements.

    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 class action seeks to recover compensation for loss and damage on behalf of consumers who acquired the affected vehicles. It does not seek to claim compensation for loss or damage which is not related to the transmission system.

    Frequently Asked Questions about the Holden Transmission Class Action

    A class action is a legal proceeding where seven or more people have claims against the same individual or corporation in respect of, or arising out of similar circumstances, such that their claims give rise to a substantial common issue of law or fact. Where these criteria are met, class action proceedings can be commenced by one or more of those people on behalf of some or all of them.

    The class action process is intended to save time and expense and avoids the need for the court to determine common issues of fact or law more than once. It enables disputes and claims involving large numbers of people to be resolved through a single case.

    You do not need to register or sign up to be a group member in the class action. However, we would encourage you to register so that we have the details of your claim and can keep you periodically updated about the progress of the case.

    Signing up to this class action will not expose you to any upfront costs.

    All costs in the proceeding will be borne by Maurice Blackburn and the litigation funder, unless and until there is a successful outcome in the class action. If there is a successful outcome, any costs payable by or to Maurice Blackburn or to the litigation funder will be deducted from, and will not exceed, any compensation you are entitled to receive. 

    All such costs are required to be considered and approved by the Court.

    As a member of the class (and not the Representative Plaintiff, in whose name the case has been brought), an adverse costs order cannot be made directly against you in respect of the determination of the common issues in the class action. 

    The litigation funder has agreed to be responsible for paying any adverse costs ordered in the class action.
