2007 Grand Prix, 1 out of 15, Hesitates taking off from a stop

Could it be the tranny if it is happening so randomly? You get ready to take off from a light and it feels as though the tires slipped on a wet surface, then it's back to normal and it won't happen again for days.

very first thing to check is your fluid level and condition. that is, if you have a dipstick for your transmission. If you don't have a tranny dipstick you will have to check it from underneath. Should have a shop do that for you.

because it's so intermittent it will be difficult to see what's happening. Scanning for trans codes. but it would be better if you could have a scanner hooked up to the trans and while you're graphing the trans have it act up and see what's happening. And save the graphs to pin point where the problem starts from.

does the traction control light come on when it feels like it's slipping?
does your vehicle have TPMS?
a worn tire or one with low air pressure could turn on traction control that would affect acceleration...
