NOTE: This bulletin applies to vehicles equipped with the a 45RFE or a 545RFE
automatic transmission (sales code DG4 or DGQ respectively) having a
specific transmission build date code (see the below DIAGNOSIS section for
This bulletin involves verifying the build date of the transmission, and if necessary, the
replacement of both the cooler return and sump filters in the transmission.
The customer may experience an initial delayed shift engagement following an extended
off (not running) period of time, generally after being parked overnight. The initial shift
engagement may feel like a delay or slip when a transmission gear (reverse or drive) is
first selected after engine start.
The customer may also experience a MIL illumination. Investigation may determine
the MIL is due to one or more of the following Diagnostic Trouble Codes (DTC's):
P0868 - Line Pressure Low. This DTC will be the most frequently occurring DTC
the delayed shift condition.
The delayed engagement and MIL condition (DTC's) may be caused by a suspect
transmission cooler return filter with a part number of 04799662AB. A suspect
04799662AB cooler return filter may cause the transmission sump filter to split at its
plastic-to-metal crimp. If the transmission sump filter becomes split at the crimp, then one
or more of the above DTC's may also occur.
|1.||Turn the ignition to the “OFF” position.|
|2.||Raise the vehicle on a suitable lift.|
|3.||Inspect for the transmission build date (Julian date) (Fig. 1). The transmission
date can be determined by inspection of the 20 digit transmission identification number
(DDDYxxxxxPpartnumber). The transmission identification number is stamped on the
left side (driver side) of the transmission oil pan flange. The first four (4) digits of the
transmission identification number are the transmission build date, in Julian date
format. An example of a transmission identification number would be :
101510492P52119684AA. The first three digits ( 101 ) of the identification number
equal the day of the year, in this case 101 equals April 11. The fourth digit ( 5 ) of the
identification number equals the calendar year, in this case 5 equals 2005. So 1015
equals April 11, 2005.
|4.||Determine if the vehicle's transmission was built on or between one of
the two sets of
Julian date build ranges listed below:
a. Julian date 0425 (February 11, 2005) to Julian date 0455 (February 15, 2005). 0425 to 0455.
b. Julian date 1015 (April 11, 2005) to Julian date 2345 (August 22, 2005). 1015 to 2345.
|5.||If the vehicle has the above condition, and if the transmission Julian
build date is on or
between the range of dates listed above, perform the Repair Procedure.
NOTE: Both the transmission cooler return filter and the transmission sump filter
MUST BE replaced at the same time.
NOTE: DO NOT use a replacement cooler return filter with a part number of
04799662AB. This filter is suspect of causing the above condition. The cooler
return filter part number is stenciled on the side of the filter's metal case.

|(AR) 1||05015267AC||Kit, Transmission Sump Filter - 4x2 (verify p/n
for specific vehicle)
|(AR) 1||05013470AC||Kit, Transmission Sump Filter - 4x4 (verify p/n
for specific vehicle)
|4||05013457AA||Fluid, Automatic Transmission, MS-9602
Special Tools/Equipment Required:
|8321||Oil Filter Wrench|
NOTE: All cooler return filters with the “AB” suffix (04799662AB)
are suspect. The
above condition may be corrected by replacing a suspect “AB” filter with a
new cooler return filter whose part number is 04799662 (with no suffix or with
a suffix that is other than the “AB” level), and a new sump filter.
NOTE: BOTH the sump oil filter and the cooler return filter MUST BE replaced
transmission at the same time. Do not replace one filter without also
replacing the other filter.
NOTE: A replacement 04799662 cooler return filter may come packaged with a
separate threaded adapter stud. The threaded adapter stud is used to attach
the cooler return filter to the transmission. Inspect the stud and note end
without threads. Install the stud end without the threads into the cooler
return filter and tighten the stud-to-filter connection to 18.6 Nm (165 in. lbs.).
Once the threaded adapter stud has been installed to the cooler return filter,
install the assembled cooler return filter to the transmission and tighten the
filter to 14.1 Nm (125 in. lbs.)
FIGURE 2 - Transmission Filters - 4X4 Shown
Use the procedures outlined in TechCONNECT® ( Service Information Tab /
Transmission Transaxle / Automatic - 45RFE 545RFE / Fluid / Standard Procedure / Fluid
and Filter Replacement) to replace BOTH the transmission cooler return filter and the
transmission sump oil filter.
NOTE: Always install the sump filter seal to the bottom of the transmission
first, then install the sump filter to the oil pump and previously installed seal.
DO NOT install the sump filter seal to the sump filter and then attempt to
install both to the oil pump.
Policy: Reimbursable within the provisions of the warranty.
