This is my first Mazda 6, and so I am not sure if this is normal. Just driving around town it seems to always shift up as soon as it can to fifth gear. It will down shift just fine as you stop at lights or stop signs, but i think it is kind of odd that it runs around in the highest gear most of the time. It seems to have plenty of power and I don't think it is a problem. The manual shift works fine also, but I sometimes forget to shift up. What do you think is this normal?
