    The transmission will need to be removed, disassembled, and repaired to correct the problem. When it comes to automatic transmissions, there are no serviceable parts or systems that can be fixed outside of the case.
    In either case, the previos owner either didn't install the correct tranny, installed a malfunctioning tranny, or didn't install one at all to begin with and cooked up a good story.

    I had the same issue on my Impala and it turned out to be one of the shifting sensoer located behind the access panel on the left side of the engine. They cost about 30-70 dollars each and their is three sensors in total. Only one needed to be replaced but I suggest you replace them all.
