Product Description
Replacement front pump o-ring, carried for 4F27E, FN4AEL and FS5A-EL automatic transmissions built for model years 1999 through 2009.
It carries OEM part number FN01-19-242 and is supplied by Precision International. Used in Ford applications of the 4F27E, FN4AEL and FS5A-EL. Every one of the 4F27E, FN4AEL and FS5A-EL automatic transmissions listed here takes this same front pump o-ring, so the part number does not change across that group of transmission codes.
