* Automatic Transmission: Most likely, it used Dexron-II or Mercon ATF. Check your owner's manual to be absolutely certain. Dexron-III and Mercon V are often compatible as well, but always double-check your owner's manual for the manufacturer's recommendation.
* Manual Transmission: Manual transmissions typically use gear oil, often specified by weight (like 75W-90, 80W-90). Again, your owner's manual is crucial for identifying the correct type and weight.
You absolutely MUST consult your owner's manual to determine the correct transmission fluid. Using the wrong fluid can severely damage your transmission. The information above is general and might not apply to your specific vehicle.
