Additional Notes

  • The Cadillac Catera (USA / CAN) 3.0 V6 carries an automatic transmission fluid capacity of 6.6 liters across the full 1997-2001 model range.
  • The 6.6-liter figure applies uniformly to both normal and severe use conditions, meaning the fill volume itself does not change based on operating environment.
  • A fluid change interval of 83,000 km is specified exclusively under the severe use condition for the 3.0 V6, with no separate interval listed under the normal use condition.
  • The 83,000 km severe-use interval reflects a relatively extended drain period for a demanding service classification, where factors such as frequent towing, stop-and-go traffic, or extreme temperatures are typically involved.
  • The capacity of 6.6 liters is consistent across all model years in the 1997-2001 span, indicating no mid-cycle revision to the transmission fluid specification for the 3.0 V6 application.
