Buick Lucerne complete transmission failure requiring replacement, just over warranty on Buick Lucerne

Some Buick Lucerne owners report experiencing complete transmission failure shortly after their warranty period, which often necessitates costly repairs such as transmission replacement to restore vehicle functionality. The average cost for transmission assembly replacement can be around $801, but this varies by model year and location, making it crucial for owners to obtain detailed estimates. Additionally, some owners consider installing a used transmission from salvage yards, which may come with a limited warranty of 30-90 days, as a more affordable alternative. Common transmission problems have been noted in Buick Lucerne models, particularly around 114,000 miles, highlighting the importance of diagnosing issues early. Owners are also advised to explore extended warranty options to mitigate unexpected repair costs after the original warranty expires. Furthermore, issues with transmission fluid, including leaks or low levels, are frequently cited as common causes of transmission problems, underscoring the need for regular maintenance to prevent major failures.
