Transmission slow to engage at first start up.

What is your question?

Transmission works perfect, no noises, slipping etc. however that's only after I let it warm up at it's first start up. Seems the torque convertor leaks out if not run for a day or so. Is there a valve or other mechanism that should be preventing this? (@80 miles now with flush done at 50K miles. Fluid looks good)

How long has your 2012 Ram 1500 had this problem?

Approx last 20K miles.
