Bring in the title, the Ohio registration, get a smog and bring the car to the aaa office. They will help you transfer it to California, get you current registration and ca plates. You have to be a AAA member though and bring cash or check for any fees.
Vehicle registration can be done at the AAA club office. It's a lot simpler and time saver than going to DMV to register your car. Be sure to check online for the documents that need to be produced for the registration
