Warmed engine to operating temp (150 degrees indicated) last night. Checked fluid level - just above the "add 1 Pint" line so measured and added that amount of fluid.
This morning... zero responsiveness from the tranny when started Park lever is slack, push buttons have no "feel" to them just in and out effortlessly
65 degrees outside - overcast
Have to wait for engine to reach operating temp and then play around with the Park Lever and Push buttons... Usually end up getting Reverse back first...very slow to engage at that. Then Drive comes back but slowly as well.
After the long drive this morning the push buttons were crisp and responsive as normal. Allowed the engine to cool (180 degrees when I parked) and same issue, zero responsiveness or feedback from either Park lever or push buttons until the system warmed and then sluggish and inconsistent response.

Hot engine fluid check reads at the "full" mark,
Changed Park cable approximately one month ago. Did not experience any changes in performance (old cable was leaking heavily)
Changed transmission cooler rubber lines under the hood and since then it's been totally out there with this condition.
