Over Drive light was flashing. Could that be low transmission fluid?

Hello, when the overdrive light is flashing, it's an indicator that there is an electrical fault noted with the transmission system. Typically low fluid will not cause this. Doesn't sound promising! Recommend that you see a local shop near you to check it out. Here are some folks near you: http://repairpal.com/toyota-within-10-miles-of-charleston-west-virginia-25302
