... sign that you need a transmission repair. Well I have a 2004 Honda accord 3.0 v6 that did just that. My dealership offered to help me with payment plans to get a Transmission rebuilt. 2 weeks later I get my car and it drives like it did before or maybe even better. Yet everytime when I turn on my car I get a buzzing sound. Once I rev the engine the sound subsides for good. No other problems with other gears . I just don't apriciate a sound so awful coming out of my car. Could a certified mechanic answer my question? Thank you guys!
