I have been reading about transmission failures. Although I have not had any thing to make me think I have a problem. I do have 120k on a 2003. I car has had an easy life. California desert car never worked hard. I have taken good care of it and done a lot of general maintenance, but no trans fluid change. Been a great car but now I am thinking of getting rid of it before the big bill comes.

Who here has had a tranny problem on these 3.0 with the GM tranny, and at what mileage?
