The oil change interval for a Chevrolet Cruze automatic transmission depends on the type of transmission and vehicle mileage.
For vehicles with 6-speed automatic transmission (6T30/6T40):
* Under normal operating conditions: every 75,000-80,000 km or 4 years (whichever comes first).
* Under severe operating conditions (frequent short distance trips, trailer towing, extreme driving): every 45,000-50,000 km or 3 years (whichever comes first).
For vehicles with CVT (CVT6):
* Under normal operating conditions: every 80,000-90,000 km or 6 years (whichever comes first).
* Under severe operating conditions: every 60,000-70,000 km or 4 years (whichever comes first).
Note: Severe operating conditions include:
* Regular trips in traffic jams or with frequent stops and starts
*Trailer towing
* Driving off-road or in mountainous areas
* Extreme driving (sharp acceleration and braking)
It is recommended to check the level and condition of the automatic transmission oil every 45,000-50,000 km or every two years and, if necessary, top up or replace it.
