Attachment III - Technical Information
OVERVIEWIn some of the affected vehicles, the transmission fluid cooler may develop a crack in the tube below the right hand (RH) mounting bracket from thermal and vibration fatigue. This may lead to a small transmission fluid leak and possible rough / harsh shifts
Dealers are to inspect the transmission fluid cooler for a grommet and possible fluid leak below the RH mounting bracket Based on the results of the inspection, dealers will perform one of the following service actions:
INSPECTION
1. Using a suitable light, look through the radiator grille and inspect the transmission fluid cooler mounting bracket for a grommet behind the mounting bolt. See Figure 1 and Figure 2.
2. If the grommet IS present NO further action is required and this procedure is complete See Figure 2.
ESCAPE
3. If the grommet is NOT present remove the radiator grille. See Figure 3.
^ Remove the two upper grille bolts
^ Slightly tip the grille outward and remove the two lower inside grille bolts
^ Slightly tip the grille outward and remove the two lower grille speed nuts that attach the grille to the front bumper cover
^ Release the three lower grille retainers from the front bumper cover
^ Remove the radiator grille
MARINER
4. If the grommet is NOT present remove the front bumper cover For additional information, refer to the Workshop Manual (WSM) Section 501-19.
ESCAPE AND MARINER
5. Using a clean white paper towel wipe the transmission fluid cooler tube below the RH mounting bracket and check for a fluid leak. See Figure 4.
^ If there is NO fluid leak proceed to SERVICE PROCEDURE 1.
^ If a fluid leak IS present proceed to SERVICE PROCEDURE 2.
SERVICE PROCEDURE 1 - GROMMET NOT PRESENT AND TRANSMISSION FLUID COOLER NOT LEAKING
ESCAPE AND MARINER
If during the inspection there was NO fluid leak detected remove the existing RH transmission fluid cooler mounting bracket and install a new bracket
1. NOTE: It is NOT necessary to evacuate the A/C system or to drain any of the transmission fluid in the following Service Procedure steps
Remove the RH and LH transmission fluid cooler mounting bracket bolts
2. NOTE: When using a wood spacer use NO larger than a 1 X 3, piece of wood for radiator protection Using a larger piece of wood may damage the radiator and/or the cooler.
Place a wood spacer no larger than 1 X 3 between the cooler RH mounting bracket and the radiator at the bracket location.
3. NOTE: It is recommended to use a die grinder equipped with a small cutting wheel. Do not use a body reciprocating saw or a Sawzall(R) to remove the bracket. Using this type of cutting tool may cause damage to the radiator and/or the cooler.
NOTE:
Place a protective cover overthe front bumper cover to prevent any damage when removing the RH mounting bracket.
Using a suitable tool, cut the existing RH mounting bracket off of the transmission fluid cooler tube and smooth any sharp edges using a Scotch-Brite(TM) pad or equivalent. See Figure 5.
4. Install the new mounting bracket. See Figure 6.
^ Install the new mounting bracket onto the A/C line upper block with the longer piece of the bracket flush with the radiator support.
^ Tighten the clamping bolt to 25 Nm (18 lb-ft).
^ Using the same RH mounting location install and tighten the iso-mount bolt to 6 Nm (53 lb-in).
^ Reinstall and tighten the LH transmission fluid cooler mounting bracket bolt to 7 Nm (62 lb-in).
ESCAPE
5. Install the radiator grille. See Figure 3.
^ Attach the three lower grille retainers to the front bumper cover by pushing the grille into the bumper cover. Make sure that all three grille retainers make an audible click when attaching to the bumper cover.
^ Hand-Tighten the two lower grille speed nuts until the speed nuts are snug.
^ Hand-tighten the two lower inside grille bolts until the bolts are snug.
^ Tighten the two upper grille bolts to 8 Nm (71 lb-in).
MARINER
6. Install the front bumper cover. For additional information refer to the WSM Section 501-19.
SERVICE PROCEDURE 2 - GROMMET NOT PRESENT AND TRANSMISSION
FLUID COOLER LEAKING
ESCAPE AND MARINER
1. NOTE: On Escape it will be necessary to remove the remaining front bumper cover for the transmission fluid cooler replacement.
If during the inspection there WAS a fluid leak replace the transmission fluid cooler. For additional information refer to the WSM Section 307-02A
ESCAPE
2. Install the radiator grille onto the bumper cover. See Figure 3.
^ Attach the three lower grille retainers to the front bumper cover by pushing the grille into the bumper cover Make sure that all three grille retainers make an audible click when attaching to the bumper cover
^ Hand-tighten the two lower grille speed nuts until the speed nuts are snug
^ Hand-tighten the two lower inside grille bolts until the bolts are snug
3. Install the front bumper cover. For additional information refer to the WSM Section 501-19.
^ Tighten the two upper grille bolts to 8 Nm (71 lb-in).
MARINER
4. Install the front bumper cover. For additional information, refer to the WSM, Section 501-19.
