I have had some issues with my car shifting under WOT...well mainly it doesn't. I went to the tuner for some final tuning and to adjust my shift points but he could not get it to shift under WOT even when he lowered the shift points really low. Also, when he had it on the dyno usually you get it into 3rd then nail the throttle and it stays in 3rd throughout the run. When he was doing this it kept wanting to downshift...it would not stay in 3rd.

He ran codes and it came back that the PRNDL switch could be the problem. I took it to a tranny place today and they are replacing it tommorrow. However, when he drove it (he about freaked out by the way, he was scared to death of the car ) he did not think that was the problem.

Do you think this will solve the issues I am having? Any other thoughts? Any help is greatly appreciated
