I just got my first Subaru. It is a 2008 outback. Shortly after buying it (used) I noticed a subtle hesitation or stutter when I am accelerating slowly. Typically at 20 and again at 40 mph (roughly). There is only one noise that is sometimes present. It may have a low grown...like you hear when you are in too low of a gear. It seams to improve as the car warms up...but does not go away. When the car is cold, it may also shift slowly from R to D.
There are no warning lights present, and the dealership apparently has not found any warning codes. I have had the fluid inspected and replace. It was clean. I have had the TCU flashed with no improvement.
Can anyone help me with this?
