Transmission Slips

Transmission Slips
I have a 2010 Escape 4-cylinder with automatic transmission and less than 3,000 miles.
Sometimes the transmission slips but only when the drivetrain is cold. After a few miles there is no slipping. Even if the ambient temperature is warm, the transmission will slip for the first few miles, but not every time.
The dealer could find nothing wrong the first time I brought it in.
Any suggestions as to what the problem may be or what I should have the dealer check?
Thanks.

I don't want to hear any problems with the trans!
I have the 2010 shop manual, there are 500 pages on the 6F35 trans. And that does not include other trans data that it refers to as being in the Powertrain Diagnosis/Emissions manual, which I don't have. Almost everything starts with checking for trans codes.
Does it slip all the time when it does, or only at a particular gear(s) shift? Doing a light-throttle acceleration from a standing stop, you can count the gear changes, the first change of course will be the 1 - 2 shift. On our 4 cylinder, gentle acceleration from a stop will yield 4 shifts to get to about 40 MPH (1-2, 2-3, 3-4, 4-5).
With radio and any other noise sources OFF, it should be easy to hear the shifts, as the PCM drops the engine RPM for an instant via the electronic throttle control (like having a little guy onboard who is an expert shifter with a manual trans ).
Any trans with more than 4 speeds is going to be pretty complex, that's the way they are all going, and we gain from the improved acceleration and better gas mileage. As long as we never have to fix them...
One simple source it lists for soft/slipping shifts is a damaged or out of adjustment shift selector lever.
