I Plan on draining and filling the trans, draining and filling brake lines, and possibly replacing my P/S fluid in my 2006 kia optima lx (automatic) pretty soon. What kind of fluid do you guys recommend? I drive 80% hwy right now and 20% city, im looking for fluids that will help make easy shifting,solid braking, etc but that's also good for when i want to get on it and pass people, etc. not really worried about price as long as it will last me quite a while. I don't know if those fluid has ever been changed in this car or not, but it has over 116k miles. Suggestions, Tips, etc? Thank You in Advance.
