Sounds like your tranny needs to be service but 1st you can try disconnectiing you neg terminal for 60 secs and reconnect and take her for a drve to see what happens after this resets the computer,sometimes you have to do this with these cars ever so often

Don't believe GM's 100k mile tune-up interval, as it just doesn't hold up under real world conditions. At 75k miles, you're due for a tune-up. If the miss/jerking happens when the engine is under load or when it's right at the upshift/downshift threshold, then a tune-up will normally fix the issue.
