Hi and welcome to the forum 
A transmission service or flush would be a good place to start. A 99 should have a torque converter drain plug so you can actually change all the fluid instead of having it flushed but either way is good.
Does the OD light ever flash?

Yeah that's more money than i want to spend right now.
I'm looking for a quick fix if there is one.
Does anybody thank that the tranny will just go out on me
or can i just drive it and not worry about it?

One of my friends just called me last night and told me that his trans in his 99 F250LD with 85K miles on it just went out.

Welcome to the forum JC
The OD light works on the transmission similarly to the check engine light for the engine. If the light has been flashing there will be a trouble code stored in the truck's PCM (Powertrain Control Module). You should get it scanned to see what caused the problem. The most common cause of a flashing OD light is a bad Vehicle Speed Sensor.

Took my truck to get the codes read this weekend...they couldn't find any error codes....now it is driving like normal again...what is going on??? Could it have gotten too hot in stop and start Atlanta traffic last week and made the light blink? should I be driving in Drive in this kind of traffic? Thanks in advance.

Have you installed a chip or tuneing..I would disconnect the batts for several hrs..then run the truck for 45min without cutting it off, I just installed a series 57 K&N filter it has the heat sheild, and that what K&N tech reccomended and now I noticed my trans holding back more when I decel..Ive gotten the superchip micro tuner II set at stock mode for now...its a 2001 4x4 lariat 5.4L..its one sweeet truck..The stop and go traffic should,nt matter unless your trans cooler is stoped up...

well driving to work this morning...Overdrive light started flashing again...the only time it is downshifting hard is when I am just about to come to a stop...so I guess when it is shifting back into 1st gear. The truck is 100% stock.
