I'm still having problems checking the auto transmission fluid in my 2002 2.5L Outback. According the owner's manual it should be checked warm with the engine idling. But if I check the dipstick with the engine idling I don't get a level--there is a thin line of fluid along one side of the dipstick. If I turn the engine off I do get a level. Any explanation for this? The mechanic at the dealer says he checks the fluid with the engine turned off.
