2002 gp gt. 88,000 when it gets up to temp. you can feel the kick of the shift, i wouldnt say the shift is too hard. But i just had the trans flushed and still does it. i checked it with a snap on scanner but no code. it did how ever have a history of the p1811 code but currently doesnt . if i turn off the car and turn it back on it may or may not go away. any ideas?
