A court ordered General Motors to provide full transmission replacements for vehicles with defective eight-speed automatic gearboxes. This ruling ends the previous practice of offering temporary fluid flushes to affected owners.
The decision addresses a long-standing class-action lawsuit regarding the Chevy Shake. This defect causes violent shuddering and hesitation in various GM trucks and SUVs.
The court mandate holds GM financially responsible for the flawed 8L90 and 8L45 gearboxes. Eligible owners of the Chevrolet Silverado, GMC Sierra, Chevrolet Colorado, and Chevrolet Corvette may receive new transmissions at no cost.
