I have noticed a few times, when the temperatures are cold (20's to 40's), and while the car has yet to reach operating temperature (i always remote start for no less than 2+ minutes) my transmission at times, 3rd to 4th gear, does a quick hesitation (with a slight rpm bump). almost sounds like a slip at shift. This is only a one time event while cold and does not repeat itself during the drive. Has anyone had a similar experience. No code has registered.
