The coolant temperature sensor, which is located behind the engine block near the firewall, senses when the coolant temperature reaches a predetermined temperature so that the transmission can shift into overdrive. This sensor and the hose preceding it can get gunked up with cystallization from the coolant (red Toyota coolant is notorious for doing this) and can prevent proper flow to the sensor i.e. your transmission may take longer to shift into overdrive or may not shift at all depending on how constricted the hose is.
