I contacted Dave @ Triple Edge and this is what he had to say
All 2000+ transmissions used quick connect fittings and cooler lines, so using a 98 trans in a 2000+ car either requires using 98-99 model year cooler lines OR you have to use to of the short return fittings that go into the transmission case due to thread size changes so you can't just swap fittings. This was intentional as mid year 99 to early 2004 had a checkball in the feed cooler fitting, but this won't fit your 98 case. A shorter return fitting will be the same thread but it will be about a little short so the line won't fit correctly in the bracket that holds the lines. So to answer your question- you need 2 of the 2000-2003 style return fittings in your 1998 transmission to work with your 2002 quick connect lines.
