2006 Chevrolet Trailblazer LT 4.2L Wot Hesitation
acts like plugged exhaust. cruising trans feels like it skips from 1st to 4th shifts at 3500 -4000 rpm. but the customer concern is at wot the trans down shifts to 2nd and accelerates till it hits the rev limiter and will not shift till u let off the throttle....
