I have a 2000 LS V8 with 90,000 miles. Very good car. replaced all coils about a year ago. I had shifting probems about 1 1/2 years. Rough engagements when shifting from park to reverse and sometimes forward too. And sometimes around 25 to 35 mph the transmissinon stays in a lower gear too long. I just heard about a TSB to reflash my pcm for a possible correction to this problem. Is this reflash usually free or cost? Or should I even worry about it.
