We purchased this car (as is) for our grandson. On our way home from the dealer, as soon as the transmission warmed up (4-5 miles), the shifting was hard and jerking with a whine coming from the transmission. Took the car to a garage which found the computer code of P1811 and were told a complete rebuild would be necessary. Went online and discovered many others had complaints of the same nature. Would hope GM would come forward with reimbursement since its transmission in this model was incorrectly designed. The rebuilding garage owner even had to go to a special school to learn how to correct this problem in the Buick Century. After paying $1,757.25 to queens transmission, Inc., in bradenton, fl (941-746-7480), the shifting is now normal.

Had transmission replaced at authorized GMC dealership May 2006.this came with a warranty. Several times over several summers since then have taken vehicle into dealership with concerns that happened after vehicle would be driven in high humidity high temperature days after traveling a minimum of 60 miles mostly on state highways that are quite rough and curvy, I.e. it would take about 90 minutes or more togo this distance. Then when in bumper to bumper traffic and trying to move forward or stopping the car's automatic transmission would cause the vehicle to shake like jumping into the wrong gear and in more than one time the car's engine would die. It always happened at low speeds so luckily we didn't loose control of the vehicle. But, the only way to stop this from continuing was to stop and park to let the engine and or cool down. We even put on the heater while driving to help reduce the temperature gauge to go below the halfway mark. This car was purchased in shelton, wa not in ky, so we never experienced this prior to transmission replacement. The service department has never been able to duplicate problem, now the cruise control has stopped working. We have dashboard warnings continually stating low oil, service engine soon (when just completed), etc.

The transmission had to be totally rebuilt due to a failure of the tarrington bearing which in turn caused the whole inside of the transmission to get chewed up and all the internal parts had to be replaced.
