Service Intervals
Check fluid at every engine oil change. Under normal conditions, replace fluid every 30,000 miles. Replace filter at 30,000 miles, and every 60,000 miles, thereafter.
NOTE:
Powertrain Control Module (PCM) maintains a "Percentage Of Oil Life Left" parameter, which can be read with a scan tool. Manufacturer recommends that this parameter be reset by a Saturn dealer whenever transaxle fluid is changed.
