Chevy Silverado Z71 with 10-Speed Transmission replaced a short 33,000 miles into ownership, with five other owners awaiting their repaired trucks, as stated by the dealer.

In the world of automotive news, two popular models – the Chevrolet Silverado and the Toyota Tundra – have been making headlines due to transmission issues.

Denis Flierl, a senior reporter for TorqueNews, has delved into these issues, sharing his insights and experiences from his 30-year tenure in the automotive industry. In a recent article, he discussed his own experience with a 2025 Chevrolet Silverado LT Trail Boss, highlighting the numerous problems he encountered in a short period.

One such issue is affecting Chevrolet Silverado and GMC Sierra owners, particularly those with 2020 to 2022 models, as well as 2021 Escalade and Yukon models. The problem revolves around the 6.2-liter engine, with owners like Aaron Sullivan, who owns a Z71 10-speed transmission Silverado, experiencing issues at around 33,000 miles. The primary concern is the potential for the rear wheels to lock up due to a malfunctioning transmission control valve.

General Motors (GM) has issued a recall (N242454440) to address this issue. The recall involves software updates that monitor valve performance and limit the transmission to fifth gear if excessive wear is detected.

Meanwhile, Toyota Tundra owners are also grappling with transmission issues. Many are hesitant to purchase the newer models due to a recent recall affecting over 100,000 engines. The 2022 and 2023 models have been affected, adding to the concerns of potential buyers.

A Toyota employee advises a prospective buyer, who is considering a 2016 Tundra with 96,000 miles or a 2022 Tundra with 45,000 miles, to stick with the older truck. The employee suggests that the newer models may have had the engine replaced under the recall.

The 2021-2024 Toyota Tundra TRD models equipped with the turbo diesel engine have been criticized for reliability issues, although specific detailed problems were not identified in the available search results.

As for the California Lemon Law, Knight Law Group states that if multiple repair attempts have been made and a vehicle's transmission problems aren't resolved, the vehicle may be considered 'defective'. This could potentially apply to Aaron Sullivan, who believes his Silverado may be a lemon and may be eligible for the Lemon Law.

In the face of these challenges, it's essential for consumers to stay informed and make informed decisions. Denis Flierl, who can be followed on Twitter @DenisFlierl, @WorldsCoolestRides, Facebook, and Instagram, continues to provide expert analysis and insights into the latest automotive news.
