5 Common Buick Enclave Transmission Problems

The Buick Enclave is a popular vehicle known for its comfortable ride and luxurious features. However, like any other car, it can have its share of issues. One common problem experienced by many Buick Enclave owners is related to the transmission.

Transmission problems in your Enclave can manifest in different forms, such as trouble shifting gears or jerking while increasing speed. These issues may be more evident with specific model years, like the 2009 Enclave and the 2018 Enclave. By being aware of these potential issues, you can take proactive measures to keep your vehicle running smoothly and ensure a smoother driving experience.

Common Transmission Problems in Buick Enclave

Transmission Shudder

One prevalent issue with the Buick Enclave is the transmission shudder. The 2018 Buick Enclave experienced hesitation and shuddering, which could be felt during acceleration. This problem is often caused by issues with the torque converter or transmission fluid. Make sure to have your vehicle checked by a professional if you experience this issue.

Leaking Transmission Fluid

Leaking transmission fluid is another concern for Buick Enclave owners. It’s essential to regularly check your transmission fluid levels and look for any signs of leaks under your car. Low transmission fluid levels can lead to other problems, such as slipping and overheating.

Transmission Slipping

The Buick Enclave has also been reported to have transmission slipping issues, especially in the 2009 model. This problem manifests as the vehicle refusing to shift into certain gears or slipping between gears. If your Enclave struggles with shifting gears, it’s crucial to address the problem as soon as possible, as it might require a complete transmission replacement.

Check Engine Light

A check engine light may illuminate on your dashboard if your Buick Enclave is experiencing transmission problems. Though this light could signify various issues, it’s essential to have your car checked by a professional mechanic when it comes on. They can help you determine if the problem is with your transmission or another component and provide the necessary repairs.

Issues with Torque Converter

Finally, some Buick Enclave models may experience issues with their torque converter. If you notice vibrations, strange noises, or your vehicle struggles to accelerate, it could be due to a problem with the torque converter. A faulty torque converter can negatively affect your transmission and could even cause complete transmission failure.

In summary, if you own a Buick Enclave, it’s crucial to be aware of these common transmission problems and maintain your vehicle regularly to prevent potential issues. Addressing any concerns early on can save you time and money in the long run.

Repair and Maintenance

Ensuring your Buick Enclave’s transmission remains in top shape requires regular maintenance and prompt attention to any issues that may arise. If you experience transmission problems, it’s best to take your vehicle to a Buick dealer for diagnosis and repairs.

It’s important to follow the recommended maintenance schedule provided in your owner’s manual. This typically includes regular fluid changes and inspection of your vehicle’s transmission. A fluid flush can help address minor issues, such as irregular shifting or torque converter hesitations, and prevent further deterioration.

If you encounter more serious problems, like your Enclave not shifting into reverse or torque converter failure, a visit to the Buick dealer is crucial. They have the experience and technical knowledge to properly diagnose and fix the issue. In many cases, a transmission-related problem may be covered under your vehicle’s warranty, saving you significant repair costs.

In some instances, using an additive might help address minor transmission issues. Additives can improve overall performance and extend the lifespan of your Enclave’s transmission. However, it’s essential to consult with a professional before using any additives, as certain products may not be compatible with your vehicle’s transmission.

In conclusion, regular maintenance, prompt attention to transmission issues, and seeking assistance from a certified Buick dealer are key factors in ensuring your Buick Enclave’s transmission remains reliable and functional throughout its lifespan.


It’s essential for you, as a potential Buick Enclave owner, to be aware of the most common issues related to transmission problems. Understanding these issues can help prevent costly repairs or replacements and make for a more enjoyable driving experience.

General Motors, the parent company of Buick, has taken strides to ensure their vehicles’ reliability. However, it’s crucial for you to thoroughly test drive the Buick Enclave and keep in mind the reported transmission problems before making your purchase.

In conclusion, although the Buick Enclave is a dependable vehicle, it’s important for you to be well-informed about potential transmission issues. This knowledge will help you make an educated decision and enjoy your Buick Enclave for years to come.
