ISSUE
Some 2007-2010 Edge, MKX, 2008-2009 Taurus-X, Sable 2008-2010 Taurus, 2009-2010 Flex and MKS and 2010 MKT vehicles may experience a
fluid leak at the power transfer unit (PTU) right hand (RH) intermediate shaft seal. The online Workshop Manual (WSM), Section 308-07B has been
updated with new tools and service procedures to assist with resolving leaks in this area. In addition, two (2) new seal kits were developed and depending
on the location of the leak must be used to prevent repeat repairs.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
This service information is intended to improve diagnosis and repair of PTU leaks. It is still necessary to use the updated version of the online WSM,
Section 308-07B to perform the actual repair.
FLUID COLOR AND DIAGNOSIS:
Automatic Transmission Fluid
Red automatic transmission fluid (ATF) is not used in the PTU itself. The RH intermediate shaft passes from the transaxle through the input hub of the
PTU, where the intermediate shaft seal is located. A red ATF leak indicates fluid from the transaxle is leaking past this intermediate shaft seal contained
in the PTU. Use the seal kit, which contains four pieces: the intermediate shaft seal, alignment washer, deflector, and seal protector tool. The
intermediate shaft seal, alignment washer, and deflector need to be installed individually and before the seal protector tool is used.
Brown/Black Fluid Indicates a True PTU Seal Leak
Use the seal kit, which contains five pieces: the PTU cover seal, intermediate shaft seal, alignment washer, deflector and seal protector tool. The
intermediate shaft seal, alignment washer, cover seal, and deflector need to be installed individually and before the seal protector tool is used. Use seal
kit, which contains the PTU cover seal, intermediate shaft seal, alignment washer, and deflector. All four parts need to be installed individually.
