trans line fittings.

Does anyone know what I need for tranny fittings on my 4l80e to go to -6an?.....

97 & up 4L80E http://www.sweetperformance.com/prod...&productId=496 The fitting with the extention on the end goes in the rear port. All LS 4l80Es are this style.

91-96 4L80E http://www.sweetperformance.com/prod...&productId=480

Whatever you do, DO NOT use NPT taper pipe fittings, The are straight pipe thread called NPSM, Some companies try to pass 1/4" NPT off as the correct fitting, You need 1/4" NPSM.

Summit has these also...cheaper, too.

ok....so what are they called, or what am I asking for when I go to the parts counter?

Cline: the longer one goes in the rear port to drop returning cooled fluid further into the transmission, correct?

They dont seem to have the 97 & later 4L80E fittings, The summit brand -6 to 1/4 NPSM for all other GM transmissions is really well priced.

The later 4L80E fittings from Sweetperformance are priced for a pair at $18.00 I doubt you will find these "special" fittings for less.
