It has 75,000 miles on it and the transmission fluid's never been changed. Just normal driving but mostly interstate so haven't been rough on it. Lately I've noticed a slight hunting, jerking, stuttering, whatever you want to call it at low speeds (under 40mph) but only when the transmission isn't up to temperature. Once it warms up it's fine. It's going into the local garage next week for a drain and fill so hopefully that will help.
Watched some videos on YT and a few of them added Instant Shudder Fix. Not planning to add it unless someone here has had some experience with it.
