The stuttering is a known issue. That is torque converter shutter. To verify, there is an additive at a parts store you can add to the fluid. Drive it for about 25 miles. If the stutter stops, it is the clutches in the torque converter that is the issue and the torque converter needs to be replaced.
The fluids and filter has never been changed. That's the plan for the weekend.
