Drive Engaging Problem

Ok so I have spent a few hours trying to search this and havent found and exact issue like mine.

When I first start the truck after sitting for more then an hour or so, The truck will go into drive but not move. If i rev it up to about 1200-1500 sometimes it will engage other times nothing. If I let the truck idle for about 10-15 min there is no problem engaging. Also if I start the truck and hold the RPM's at 1000 for a min or two the tranny will engage fine. Does anyone have a straight answer for me?
The tranny shop I called said maybe the "drain back valve" or the pump. Im not super worried about, if it goes it goes, but Im about to make a 5000 mile round trip next month (not towing anything) and dont want it going half way through the trip.

Forgot to mention, its benn doing this for about a week. Changed the fluid and filter in the tranny. Fluid still looked good and no bad smell. Also this is just my daily driver truck. I do not tow anything with it besides a few cases of beer on the weekends.

Ck the fluid level before starting the eng in the am. Should be not more than 1 inch above the full mark. If it is more than that, the fluid is draining back out of the converter. If it has been rebuilt before, it may have a modification that creates full time lube. Not a bad thing but annoying. My truck has it and if it sets for 4 days, it won't even move when I first start it up. I just let it idle for 20 seconds and the tc fills up and it goes right into gear.
Other wise, trans is worn out.

Heres an update. Took it to the transmission shop today and all of my forward clutches are burnt up. $2300 for a rebuild and new torque converter. Comes with a 2yr/24000 mile warranty, not too bad I guess. Thanks for all the input

NOt a bad price, but if it ever needs it done again you could have had a BTS or John Woods... Then you would have had a real transmission!!
