I had a similar issue with the same symptoms as you described and no codes. I did a transmission flush and filter. This did not help but it needed changing anyway. I added Lubegard 60902 Automatic Transmission Fluid Protectant and seemed to help some. Long story short it ended up being the Throttle Position Sensor. May or may not be your scenario...

Thanks I will look into that.
