Ford released a TSB specifying MERCON V as the current fluid for MERCON /DEXRON III applications.Should state so on atf dipstick.
Yes, but not everyone has a 98-99 tec.All 5 of my 98-99 tecs specify merconV on the dipsticks?
IIRC, The AX4N was the only transmission that started requiring MERCON V in 98. The AX4S still used MERCON.Excuse me. You were servicing a 99 tec. I believe ford first started requiring merconV during the 98 model year and several years later stated it should replace mercon in all applications. P.S.: I am quite aware not everyone has 98-99 tecs.
