asked by on

The sound comes and goes I hear it with the driver side window down coming from under center, I hate to think it may have anything to do with the transmission, because that is working fine no troubles at all. I only hear this rattle when I give it gas and then sometimes it makes no sound. It also way as soon as I let off the gas pedal, could it be a cable or a gear of some sort into the transmission although the speedometer is working fine also so I am not sure. All I know is that it is directly related to the gas pedal.

My car has 144000 miles.
My car has an automatic transmission.

Hi there. Sometimes the rattling sound during acceleration is caused by a loose bracket on the exhaust system or another mechanical component. The issue could also be a small exhaust manifold leak or something entirely different. The problem with diagnosing sounds is that it can only be done onsite; while a professional mechanic completes a road test. It might be a good idea for you to contact one of our professional local mechanics to complete an engine is making a noise inspection; so they can trace the issue and recommend the right repairs.
