If your Over drive light is flashing and check engine light came on in a 2002 sentra what is the problem?
Alot of the time, the over drive light will flash if the transmission overheats. It protects itself by automatically shifting out of overdrive. In some cases, people put too much transmission fluid in, which is a big no no. In other cases, you have bigger problems. With your check engine light, bring your vehicle into any shop that offers diagnostics and they can tell you...for a price. Or, depending on where you are, go into Autozone and they will do it free. A lot of other parts stores will rent out for free too (Oreilly's).
