Heat is the killer of a transmission and overdrive not working means you are either low on transmission fluid from a leak, and or you transmission needs a rebuilt. Have a shop perform a diagnosis on it.
Hi it's not leaking. And it shifts perfect when cold it goes into overdrive but once it gets a little warm kicks out. Could it be bad circulation? Like transmission oil cooler clogged?
My guess is the overdrive band is worn or burnt. To replace you have to open the transmission to replace, and when the shop is doing that, they will rebuild the whole transmission to warranty the work. for a 98 truck, my guess is you have over 100 to 150K miles, which is typical at this age to be rebuilding the transmission. So the question is, do you want to spend $2K fixing a 21 year old truck?
