Automatic Transmission problems of the 2005 Buick Lesabre

The contact owns a 2005 Buick Lesabre. While driving between 45-50 mph, the vehicle shook excessively. There were no warning indicators illuminated on the instrument panel. The vehicle was taken to an independent transmission shop and the technician stated that the failure was contributed to the inner wear in the transmission. The vehicle was repaired. The failure mileage was 84,892 and current mileage was 86,000. Updated 8/28/09 updated 09/09/jb.

At approximately 24,000 miles I started feeling a harder than normal shift between second and third gears. By the time the odometer reached 26,000 miles the shift was somewhat severe with a pause between second and third. I took the car to the local dealer who supposedly installed some type of "kit" which did not eliminate but greatly reduced the problem. I now have 37,000 miles on the car and the problem is getting progressively worse once again as well as hard shifting between first and second and sometimes when I shift from drive to reverse while the car is not moving. I have not returned to the dealer because I am now 1000 miles over the warranty and the first time I took it in the dealer told me the repair would take one day and kept it nine days. I emailed Buick with a complaint but got no reply.

Consumer stopped on an incline waiting on a traffic light and discovered when removing foot off the brakes vehicle rolled back. Consumer put vehicle in first and second gears and it still rolled back. This only occurred on inclines. Had not been to dealer, no repairs were done. . Called dealer service department, and they said there was nothing they could do. Consumer used onstar and the diagnostic module and they found that nothing was wrong with the engine, and instructed consumer to call dealership. Had not contacted manufacturer.
