if it is only doing it overdrive it could be the servos for that gear going out. if its not catching all the way or slipping it will cause the engine to rev higher to try and maintain the speed you are going. i would have the transmission looked at

with the 700r4 and any eltronically controlled transmission there are things called servos. the job of the servo is to shift the transmission into the gear you have selected. if a servo is not working properly it will not shift the gear either all the way which would cause you high rpms or not shift at all.
