My Paseo's overdrive does not start working until a mile down the road. It was worse during the winter and we changed the filter and fluid. But the problem is still there. It has something to do with...
Hello. My name is Toyota Ed. Please allow me to assist you.
The truth is, your Paseo is working properly.
To lessen emissions, Toyota does not allow the overdrive to engage until the engine temperature reaches 177 degrees F.
The "OD allowed" temperature is determined by the coolant temperature sensor on the engine. This sensor prevents the computer from allowing the OD to engage until the 177 degree threshold is met.The warmer the coolant is, like in the summer, the faster the 177 degree plateau is reached. In colder temps, like in winter, it takes much longer for the coolant to warm up to the desired temperature, thusly taking longer to shift into OD.
If the overdrive engaged before 177, cold-engine emissions are more abundant.
There is nothing that can be done to change the point at when the OD is permitted to shift.
So, your car is in excellent working condition. Nothing to worry about, now that you understand the basic design.
