| POWER TRAIN - AUTOMATIC TRANSMISSION | |||
| 01/01/2001 | |||
| The vehicle hesitates and then clunks into gear when accelerating from a full stop. i brought the vehicle to the dealership for repair but they were unable to fix the problem. they informed me that cadillac was aware of this problem as it seems to be inherent, but as of yet they do not have a solution and i should call them back in about one month for a progress update. i hope this is true. *ak | |||
