Best to have a Transmission Expert look at it to see if any further damage has occurred.

Possible Solutions
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak
in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Their all Transaxles Codes
Being 11 years old,I think you just bought
a car, the previous owner got out of, because
you need a Transaxle Rebuild.
11 years is a long time for a transaxle
May be the second round for it.

These codes are for a cylinder misfire. Take it to a pro to find out which one(s). Could be an injector or an ignition coil
