Service Intervals: Transaxle
WARNING: This page is about a different car, the 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
It is not necessary to check transmission fluid. A transmission fluid leak is the only reason to check transmission fluid level. Transmission fluid should not be changed under normal operating conditions. Under continuous extreme operating conditions (trailer towing, heavy city traffic with ambient temperature more than 90°F (32°C) or delivery service), replace fluid and filter every 50,000 miles.
