The GMC Acadia is a popular SUV that offers a comfortable ride and versatile performance. However, you may encounter some transmission problems with certain models, affecting the overall driving experience.
These issues might range from shuddering to overheating, and it’s essential to be aware of the potential problems before they turn into significant concerns. Knowledge of common transmission troubles with the GMC Acadia can help you in preventing or addressing them effectively, ensuring a smoother ride for you and your family.
Common Transmission Issues and Symptoms
Overheating and Solenoid Issues
One common issue with the GMC Acadia transmissions, particularly the 6-speed 6T75, is overheating. This can happen when the moving parts inside the transmission generate more heat than the fluid can dissipate. To prevent this issue, make sure your transmission fluid is clean and at the proper level. Besides overheating, solenoid problems can also affect your Acadia’s transmission performance. Faulty solenoids may lead to delayed or erratic gear shifts.
Leaks and Slipping
Another prevalent problem with GMC Acadia transmissions is fluid leaks. These can cause slipping or slow shifting. If you notice that your vehicle’s fluid levels are low, address the issue promptly by locating and repairing any leaks. Additionally, check the transmission gasket for damage, as it can also cause fluid leakage. In case the fluid is contaminated due to aging, consider changing it or performing a complete transmission flush to maintain proper function.
Torque Converter and Clutch Problems
The torque converter in your GMC Acadia might experience issues such as shudder, which occurs when the vehicle shakes or trembles convulsively. This can happen while driving uphill with the overdrive gear engaged or when shifting to overdrive. To avoid torque converter problems, make sure the transmission fluid is in good condition and at the right level, as it plays a vital role in the converter’s operation.
Lastly, clutch problems may also affect the transmission’s function, causing it to fail in shifting gears properly. Regular maintenance of the clutch and other transmission components will help ensure smooth and reliable performance from your Acadia.
Year-Specific Transmission Problems
2014 to 2018 Models
During the first-generation of GMC Acadia, specifically from 2014 to 2018, transmission problems were quite common. The 6T70 and 6T75 transmissions were used in these models and were known for their shifting difficulties. Drivers reported various issues such as transmission failures, which often led to transmission rebuilds under warranty. Issues with the first-generation Acadia transmission can affect its towing capacity and overall power output.
Improper gear changes, rough shifts, and weak acceleration were some of the main concerns reported by owners of 2014 to 2018 models, especially the 2016 GMC Acadia. Problems like these compromised the overall driving experience of these crossover SUVs.
2019 to 2022 Models
The second-generation GMC Acadia, which began in 2019, saw the introduction of new 9-speed 9T50 and 9T65 transmissions from General Motors. These 9-speed transmissions aimed to improve the performance and fuel economy of the mid-size SUV. Although the 2019 to 2022 models were supposed to resolve the transmission issues found in the previous generation, it is still essential to be aware of any potential problems.
For the 2022 GMC Acadia, some common transmission problems may still surface due to its complex design and the occasional need for updates. In this regard, it is crucial to monitor your vehicle for any aforementioned concerns and to address them immediately with a professional if you experience improper gear changes, rough shifts, or unusual noises during operation.
Overall, when considering the GMC Acadia, it’s important to be aware of the year-specific transmission problems to make an informed decision.
