transmission shifts while on the highway on 2000 Nissan Maxima

I have 65k miles on my car. Whenever i drive on the highway and the engine is still cold, it takes about 4-5 miles or 20 min of driving for the car to shift into overdrive. When the car was new the car shift into overdrive right away, but it the last 2 yrs, it takes longer to shift into OD. I read online that it could be some type of solenoid. Is this a transmission problem or just replace the solenoid? thanks

dont think it is the soloniod. it may be a sticking valve in the valve body. when was the last time you had the fluid serviced? thats a good start with a valve body modifier added as well. Roy
