Will a drain and refill help? (2005 Honda Accord)?

I have a 2005 Honda Accord LX. I've had it since January. My dad had it shipped to me when he got a new car. (About 166k on it now) Anyways fast forward to now the car has been stuttering some when I let off accelerating. I checked the transmission last Friday and it was very low. It was reddish pinkish I guess. Didn't look or smell like anything was wrong with it. Just low. I added some Honda fluid to it and drove it around some. Didn't notice much of a change. I didn't drive it Saturday or Sunday since I was out of town. I drove it to work today and noticed it rode better didn't notice too much stuttering and if I did it wasn't as rough as last week. The car even got up faster better. Should I still get a drain and refill to be on the safe side? I know my dad takes care of his stuff so he was pretty regular with the maintenance. I've only got oil changes and tire rotated since I've had it. There's no check engine light on or any other lights. Would it be worth getting the drain and refill? It's about 82 dollars at the Honda dealer where I'm at. Thanks in advance.
