Some Hyundai Sonata owners report experiencing issues with fluid pressure buildup in their 5-speed manual transmission, often linked to common problems such as transmission fluid leaks, which may stem from faulty transmission hoses. Many drivers have noted that low or contaminated transmission fluid can lead to significant performance issues, including difficulties in shifting gears. Additionally, some owners of the 2014 Sonata report transmission troubles, such as delayed or harsh shifting and transmission slipping, which can further exacerbate pressure buildup. It is crucial for owners to ensure that the correct amount of transmission fluid is used during replacement to avoid pressure irregularities and to check for any underlying issues that may contribute to these problems. Addressing these factors promptly can help in effectively resolving the pressure buildup issue.
