Use a scan tool (OE factory tool recommended) to reset the ECM. Post-Adapt Road Test After resetting the ECM, a road test is required. Start the engine and warm it to normal operating temperature. Perform a thorough road test with multiple accelerations from a stop until proper shifting is obtained. Solenoids Solenoids should be cleaned to remove debris that results in sticking and malfunction.
