No, I'm smart and bought the proper transmission (manual) for my driving style. I'm not the one starting with one thing and trying to turn it into another.

You asked a question, and you got an answer. It's nobody else's problem but your own if you're not satisfied with it. For what it's worth, I'm not in 5th until 40+ MPH anyway. I don't see why you're pissing and moaning about an automatic doing what it's suppose to do at low speeds and low temp/op conditions. The quicker the engine reaches optimal temp, the quicker it gets to max efficiency. Modifying the programming to get into 4th as quick as possible under cold conditions will result in it taking LONGER to reach optimal temp, and thus burning more fuel anyway, defeating the entire purpose. You got 28 MPG for a variety of other reasons. Not because you can't get into 4th for one mile of your seven mile commute.
