Murnane2000

We have 2004 Holiday Rambler Atlantis with a V10. Whenever we use cruise it does downshift to third lockup converter disengaged, then after a few seconds the converter engages. AND YES the ENGINE SCREAMS like a Formula one race engine. The wife says im gona blow it up, But its reving at around 3500 to 4000 rpm on a pull. It has 47000 miles and I dont think it will ever blow.
