    Had the same thing happen on an 01 suburban with 41k on it. Dealer replaced all the seals and orings in the tranny and it was like new. They said an oring somewhere had failed.
    You may want to try and have it reflashed before they tear into it, because at times you can lose the program(dead battery etc.).
