The 1st thing to do is have a test run on the transmission control module to see if any trouble codes are present, next have you ever serviced the transmission, fluid and filter change, should be done at 60,000 miles, on occasion this can cure problems like yours.

you're more than likely looking around $80.00 to $150.00, depending on where you go. If you do it yourself, parts should be around $35.00 or so.

if AAMCO charged you for this faulty diagnosis (sounds like they guessed), because the PCM rarely is the problem on any GM product, less than 3% is the factory stat, and yes they track these things, anyway if they charged u make them refund the money because they screwed up, u say a pin is an open circuit? that is where to concentrate your focus.i
