2010 Jeep Wrangler intermittent Auto Transmission slip.

What is your question?

The transmission seems to work fine when cold, but slips completely when it heats up. Could this be a solenoid or something? It doesn't seem to me that it would work at all if the problem required a total tranny replacement. Is there a way for me to test for this at home to verify if the tranny can be repaired or needs replaced?

What makes this problem better or worse?

Seems to work fine for a little bit until it warms up
