Ive noticed that when Im going downhill and about to make a left turn on to the next street, my RPM meter goes from 2 than under 1 really quck and goes back to about 1.5. Is that normal or there might be a problem? By the way, Im driving auto and not SS. Thanks guys.

 

Sounds like the uphill/downhill detector kicking in and downshifting?

Fee fi fo fum!
I smell good FAQ material, yum yum!

 

That was brought up before and its normal. Something to do with the Logic Grade Control.
