I don't want that, I AM a passive driver. Just saying that the shifting pattern of the car feels weird and wrong. Every car I've ever had, holds in gear longer when the car needs it (like when climbing a hill) and then upshifts quickly (when the car is accelerating downhill for example). This car does the opposite, how is this possible?

The transmission holds gears going downhill to help maintain speed for you that way you're not riding the brakes.
Under normal driving, it constantly shifts to the highest gear possible to keep the rpms low and in turn helps you save fuel.
If the shift points aren't right for you then you'll have to drive the car harder. Like others have said, the harder you drive it, the later it'll shift especially once it learns your style.

Thanks for that information
But sometimes when I driving at 60 mph them let it go the gas and them push the gas a little rpm goes to 2000 rpm to 2800 rpms no sense to me, I dont know if the aftermarket AEM cold air intake cones with sensor, this sensor might be bad???

No need to disconnect the battery to reset the memory, just pull the ECT fuse out from under the hood (fuse box on driver side behind headlamp, under plastic cover) for about 2 minutes and voila! Just drive it after to relearn values.

i just brought this model yesterday, felt this when i was this driving but the other gears felt fine. prior cars i had didnt have this type of shifting. tried the battery trick but didnt disconnect it for 20 mins or so. going to try the fuse box method. also.. i parked my car on an steep incline today and when i went to the car to drive i was rolling back... soooo its giving me a feeling its the trans... hopefully not.
thanks guys.
