The first step in troubleshooting a noisy transmission should be a road test. This allows the technician to verify the complaint under normal operating conditions and potentially identify the conditions under which the noise occurs. It's a non-invasive and cost-effective initial diagnostic step before proceeding to more intrusive and potentially expensive diagnostics.
