Early model Subaru Automatic transmission diagnostic code retrieval procedure. This procedure is specifically for 98 Subaru OB but stays the same for all similar models. I do not believe this will work for the 2.5 SOHC Subaru Outbacks. Locate the diagnostic connector under the dash then follow the procedure. TCM will flash codes through the “AT Oil Temp” lite. Please post any questions to comments below, thank you.
