Sounds to me the coolant temp sending unit has failed. Replace it with a new one.
Have the coolant temperature sensor checked, or replace it. (under the intake manifold)....The overdrive will not engage, unless the computer reads that the coolant temp. is at a certain level.

The engine coolant temperature sensor is usually on the front of the engine. The coolant temperature sensor will be in the vicinity of the thermostat housing.
Have you checked the cars thermostat?
Be careful there is a temperature coolant switch mounted next to the thermostat housing. I thought this was the sensor and replaced it by mistake. There is another sensor.
To monitor the temperature of the engine coolant.
In most vehicles there are different temperature readings, especially in newer vehicles. The TEMP light usually means the Coolant temperature in the radiator. If a warning light comes on it usually means your vehicle is overheating and should be checked out by a mechanic asap.
Coolant temperature sensor is located on the front of the engine. The coolant temperature sensor is a few inches above the thermostat housing.
you prob need to have your coolant checked out because when you work your engine the coolant is what keeps it at a good level so you should have the mixture of coolant to water checked out it should be 50/50
