Only a fast question... May 22, 2005, 09:41:52 PM So much time i needed help about the auto trans (C5). The correct type of fluid for this tranny was DEXRON II - III or Mercon , right ? Yesterday i nearly bought Type F Fluid......And it´s 11 pints (5.2 L) ......oh yes Quote Selected
Re: Only a fast question... Reply #1 – May 22, 2005, 10:47:32 PM Yes, the correct fluid for a C5 is Dexron II/III. The dipstick says "Type "H", but Type H is just Dexron (or at least Dexron meets Type H specs). Don't put type F in it unless you want to chirp the tires with every gear change until the tranny fails. Some people will add a quart or two of Type F for a firmer shift feel, but don't do a whole fluid change with it. Quote Selected
Re: Only a fast question... Reply #2 – May 23, 2005, 07:19:37 AM I've had only F in my Bird's AOD since '99 and have been using it the wifes Grand Marquis since early '98, but not everyone should necessarly do same as me..The reason it's in the Bird is I race it and will firm up the shifts a little(but nothing drastic, the Trans Go shift kit made 10 times more difference). The Grand Marquis tranny started slipping on the 1-2 shift at 33K mi. With the F(still slipped) and a B&M electronic shift improver, it just crossed 100K mi last week and still works fine...
