Thanks guys! Both responses are excellent.
I had my trans serviced last June. The filter was replaced and I'm guessing that some fluid was lost during that process. 2.5 quarts of 80-90 gear oil was replaced and 1 quart of limited slip additive.
The last couple of months I have felt the trans jerk lightly while rolling, foot off the gas down a slight grade. I have a steep uphill incline that produces a barely audible high pitched whine while accelerating. A couple of days ago a made a fast but wide arcing 90 degree turn and lost forward momentum for a few seconds.
My first thought was CLUTCH! Later I got to thinking, low trans fluid. So I will tackle the fluid level as soon as I can and not drive the car until I do. If the above description rings a bell with anyone, please let me know.

Thanks again!!!
