Overdrive Malfunction

I have a 2000 Kia Sephia. Yesterday the O/D Off light came on as well as the check engine light. I don't know if it is the O/D System button that is stuck or if I messed up the Overdrive. Now my car has slight trouble when I accelerate. Can anyone give me advice, or a price for having it repaired?Thanks. :banghead:

Yo, what you do is disconnect the negative battery terminal and let the carsit like that for at least 20 minutes. What your experincing is a bug that was installed by Kia so this should work.

I had an engine light on a 1996 Sephia. The mechanic changed me $100 to change a temperature sensor.
