Software updates to the Powertrain Control Module (PCM) are available that can improve shift quality for rough up and/or down shifts. On higher mileage vehicles, other problems may cause shifting issues. Diagnoses may be required to isolate the cause. Anytime major transmission repairs are made the PCM software should be checked and updated as necessary.
"False" trouble codes may cause erroneous illumination of the Check Engine Light. Updating the PCM software can often correct this concern.
If the engine does not crank (or cranks but won't start), the wireless control module (WCM) may have locked up. This is due to static discharge through the ignition key. A revised model should be installed, but simply disconnecting the negative terminal of the battery for thirty seconds will temporarily reset the module so you can start the car.
Intermittent static from the satellite radio may mean the satellite radio receiver needs to be replaced.
