ISSUE
Some 2006-2007 Explorer and Mountaineer, 2007 Sport Trac, and 2007 Expedition vehicles may exhibit the following diagnostic trouble codes in the transmission control module (1CM) memory with or without the wrench light on. The codes include the following; P0658, P0657, P0972, P0973, P0974, P0975, P0976, P0977, P0978, P0979, P0980, P0981, P0982, P0083, P0961, P0962, P0963, P2763, P2764, P0985, P0986, P0711, P0712. The cause is contamination at the mechatronic assembly.
ACTION
Follow the Service Procedure steps to correct the condition.
NOTE
IF THE MECHATRONIC ASSEMBLY WAS BUILT WITH A FOAM BARRIER STRIP, REMOVE AND DISCARD, REMOVE ANY SOURCES OF CONTAMINATION, AND INSTALL A NEW FOAM BARRIER STRIP.
SERVICE PROCEDURE
Remove the source of contamination from the transmission control unit (TCU)/solenoid connections and/or at the transmission fluid temperature (TFT) window. Install the foam barrier strip to prevent recurrence.
1. Remove mechatronic assembly using the Workshop Manual (WSM), Section 307-01.
2. Remove the six (6) long fasteners from the TCM unit. (Figure 1)
3. Carefully separate the TCM from the mechatronic assembly. Do not separate the two halves of the main control during this procedure.
NOTE
IF THE WRENCH LIGHT IS NOT ILLUMINATED THE CONTAMINATION MAY BE DISLODGED FROM THE TCU/SOLENOID CONNECTORS AND FLOATING WITHIN THE HYDRAULICS SYSTEM.
4. Inspect the TCM at the following locations for metal chips or other metallic contamination.
a. Closely inspect both sides of the TCU blades for machining chips or metallic contamination. (Figure 2)
b. Closely inspect all solenoid terminals for machining chips and or metallic contamination. (Figure 3 and 4)
c. Closely inspect the TFT window for any machining chips and or metallic contamination. (Figure 5)
5. Prior to installation of the protective strip, remove all machining chips and or other metallic contamination from these areas with a clean, lint free cloth.
6. Install the new foam barrier strip over the blades of the TCU, no special barrier strip is required for the TFT. (Figure 2 shows before foam barrier strip is installed, Figure 6 shows after the foam barrier strip is installed).
7. Reinstall the TCU on to the main control. Install the six (6) long bolts into the TCM unit. Tighten to 53 lb-in (6 N.m). (Figure 7) Reinstall/verify the cooler bypass valve (spring end into the case first, "point" down), reinstall pump seal adaptor, and four (4) center support seals following WSM, Section 307-01.
8. Reinstall the mechatronic assembly following the WSM, Section 307-01.
9. Install a new fluid filter, and reusable gasket following WSM, Section 307-01.
10. Set the transmission fluid level following the WSM, Section 307-01.
11. Clear all DTC(s) from the TCM.
