The manual will specify the correct type of fluid (Dexron, Mercon, etc.) and may even give a specific GM part number. Using the wrong fluid can severely damage your transmission.
If you don't have the owner's manual, you can try:
* Checking the transmission dipstick: Sometimes the recommended fluid type is printed on the dipstick itself.
* Looking up your VIN: Using your vehicle's VIN number on the Chevrolet website or a parts website might allow you to identify the transmission and, therefore, the correct fluid.
Do not rely on general advice; always verify the correct fluid type for your specific Suburban's transmission.
