The transaxle, half case seal, and water pump of my lower than average mileage 02 DHS were replaced by a local Cadillac dealer. The trans was replaced with new GM. Since the repair work, I have experienced a significant loss in gas mileage, going from 17 city to approx. 11. The motor has also become extremely noisy. Prior to the service I could stand next to the running engine and seriously be unable to tell it was running. I have returned the vehicle several times and service has not offered a solution. They state that the trans needs to re-adapt to my driving habits over the course of 1000 miles, and have no explanation for the noisy motor. Right now the fuel used read out and trip od read : trip 69 miles, fuel used 7.2 gallons! I would highly appreciate any advice you can provide. Thank you for your time and consideration.
