Hello and welcome to JustAnswer!
Can you describe the problem a little more? Does it not shift into second at all? Does it slip into second or third?
Your Jeep has a hydraulic fan clutch that will make some extra fan noise in the morning for about the same time frame you're talking about. Are you familiar with this fan noise, and this is something different?
Have you checked the fluid level and condition?

it does not shift into second until it has run a little while on the road. the rpms go up and it sounds like it is hunting for the gear. it will eventually about one fourth mile, go into the second gear. i haven't noticed any extra fan noise when this is occurring. the fluid level is fine. as to the condition of the fluid, i haven't had it changed in 40,000 miles, the vehicle has 188,000 on it now.

Ok great. You've got a couple possibilities. You may have a governor pressure problem, but that would normally happen at all shifts, and it shouldn't matter if it is cold or hot.
You may have a kickdown band that is far out of adjustment. This is the band in the front, and it is only used for second gear. It needs to be adjusted every 30,000 miles, at every fluid change. If it has never been adusted this is the place to start now.
If adjusting the band doesn't take care of it, the most likely cause is leaking rear clutch seals. When they are cold they allow fluid to leak past the seals when it tries to apply the clutch piston, but after a few minutes the fluid starts to warm and it warms the seals up. This makes them swell a bit, and it also makes the rubber more pliable so it seals better. Heat and age make the seals hard over time. This was common in the older Torqueflite transmissions, and if yours has lasted 188,000 miles without being rebuilt, that's great! It wasn't uncommon to have seal leakage on these starting at 50,000 miles.
