To find out for certain:
1. Check your owner's manual: This is the most reliable source. It will specify the exact type of transmission fluid recommended by the manufacturer.
2. Check the transmission dipstick: Sometimes the recommended fluid type is printed on the dipstick itself.
3. Look up your VIN: Use your vehicle identification number (VIN) on the Chevrolet website or a trusted online parts lookup tool to determine the transmission type and recommended fluid.
Do not rely solely on general advice. Using the wrong transmission fluid can severely damage your transmission. Always use the fluid specified by the manufacturer.
