Automatic Transmission

The DRIVE range can be selected when towing. However, if frequent shifting occurs, select the 3 range (for a four-speed automatic) or select a lower gear using the AutoStick shift control.

NOTE:
Using a lower gear while operating the vehicle under heavy operating conditions, will improve performance and extend transmission life by reducing excessive shifting and heat build-up. This action will also provide better engine braking.

If you REGULARLY TOW a trailer for more than 45 minutes of continuous operation, then change the automatic transmission fluid and filter according to the interval specified for “police, taxi, fleet, or frequent trailer towing.” Refer to the “Maintenance Schedule” for the proper maintenance intervals.

NOTE:
Check the four-speed automatic transmission fluid level before towing. Six-speed transmissions do not require a fluid level check before towing. If, however, you notice fluid leakage or transmission malfunction, see your authorized dealership service center for assistance.
