Default 4L60E shift ????

How many of you guys with the 4L60E will your Trans shift into 4th gear at WOT. I got mine built about a week ago and I did a WOT blast the other day and at 128 mph at 6500rpms it will shift into 4th gear.

It never would do it until I got it built. It would always hit the rev limiter. I could let off the throttle a little and it would shift, but not WOT.
