    Default TSB list for 04 Colorado

    I recently purchased an 04 Colorado and was looking for a detailed list of TSBs that pertain to that year. I want to know if there is anything major that needs to be addressed. But all I have been able to find is a list of 200 titles and summary, but no detailed descriptions.
    This is a list a few of sites I found, but with limited information

    Any help on which TSBs are important to make sure have been fixed?
