But it's just alittle needless, as we've recognized, to pull into fifth at 40. The engine maybe doesn't have enough torque to pull smoothly in top gear at that speed and the computer is getting frusterated, and in the attempt to maintain good fuel economy, if you're not stomping the gas pedal, it'll remain in that gear. Some transmissions from other car makers are just they opposite-downshift-crazy, to create the illusion of speed that comes with the shift-shock. haha just tryin to put my two cents in...not sure if it brings much to the party, but hey, it's worth a try =]

It just sounds to me like the computer needs alittle reprogramming to move around the shift points alittle and add some logic to its thinking. btw hope I'm not really repeating stuff....I did the lazy thing and didn't read all the posts

Mine doesn't shift into 5th gear until 49-50 mph.

If I slow down to 40, with a little gas it will start to lug.

Just a touch for pedal and the torque converter will unlock or shift into 4th without any problem and accelerate.

Hard to believe they have screwed up the programming in the later builds.
