Subaru automatic transmission markings are usually located in three places:
1. On the automatic transmission housing: A metal plate with markings must be stamped on the side or top side of the automatic transmission housing. It may be coated with grease or dirt, so it must be cleaned to read the markings.
2. At the diagnostic connector: Some Subaru models have a diagnostic connector, which is usually located under the hood. The automatic transmission marking may be indicated on this connector.
3. In the owner’s manual: Information about automatic transmission markings can also be found in the owner’s manual for a specific Subaru model.
