How often can I add Trans Tune to a 2003 Buick Park Avenue transmission? [SOLVED]

Can I put a second can of Trans Tune in my transmission? The first can cleared up the slipping when I added 5 months ago, but it slipped once yesterday. Car is a 2003 Buick Park Avenue.

Thanks for the question JoAnn. Even though our recommendation for adding Trans Tune is one can (16 ounces) per transmission fluid interval, you should have plenty of room in your transmission to add another pint if the fluid level isn’t too high (see ATF dipstick).
