2004 Cts w/ 89160 miles complete and sudden loss of trans fluid. Had towed to gm dealer and was advised that the trans lines to the radiator were "stripped " and both needed replacing. We bought the car new and this area has never been serviced or touched. Dealer that worked on problem is st.
Have a noise in rear-end when accelerating up to speeds. When letting up on accerlator noise quits, but as soon as I give it gas it hums( like) very loud. Have had two Cadillac dealers check it and told not to worry about it nothing is wrong and that , that' is the characteristic of the 2004 Cts. This is hard for me to believe since I have had 8 Cadillac over the years and have never had a problem of this nature.
