Vehicles equipped with an automatic transmission may exhibit an increase of engine RPM (of up to 500 RPM) when braking. Our technicians tell us upgraded powertrain control module (PCM) software is available which should correct this concern.
Vehicles with a 7 speed automatic transmission may experience a harsh downshift from 4th to 3rd gear on deceleration. Our technicians tell us revised control module software is available to correct this concern. On higher mileage vehicles other faults may cause transmission shifting issues. Whenever a transmission repair is performed, the control module should be checked for the latest software and updated if necessary.
A "tapping sound" may develop from the drivers side of the engine. The noise may be associated with the variable valve event and lift actuator. Our technicians tell us a software update for the powertrain control module (PCM) is available to correct this issue.
