Hi all - I am rebuilding the 3.5L V6 motor & trans in my 2002 Intrepid R/T I remember reading somewhere on an Intrepid forum that there is a source for a higher oil pressure spring for the 1999-2004 3.2/3.5L engine readily available. Would like to increase the pressure by 10 psi or so. Does anyone know anything about this source?

I am also rebuilding the 42LE transaxle & need a stiffer pressure regulator valve spring for this unit - would like to increase the line pressure by 10%. I have contacted Sonnax & they do not supply this part for this trans - high performance parts for the 3.5L V6 & 42LE trans are basically non-existent.

If anyone has any suggestions, please comment.
