Wish I had got the manual, but my wife refuses to learn how to drive one.

(May have to switch down to 7 and back to 8 twice.....I haven't done it since the flush...I'll try again today....but i was successful in keeping it on 8 cylinders for a 40 minute freeway cruise with CC on...and it will automatically downshift for you at a certain point while slowing down.)
I'm in the same boat....momma don't drive manuals....lol

Klayman is right. The downshift then upshift is what keeps AFM from reengaging. But I can tell you both once the issue becomes bad enough, the shudder will appear in V4 and V8 modes, as well as shuddering while shifting on light accel. Then it started the shudder at interstate cruise speeds if there was any incline (V8 or V4). That's when it went in for service. My car went from occasionally shuddering to the above in about 2K miles.
