This article supersedes TSB 13-4-2 to update Service Procedure

ISSUE:

Some 2009-2011 Edge, Taurus, Flex, MKS, MKX and 2010-2011 MKT vehicles equipped with a 6F50 or 6F55 transmissions and built on 3/13/2009 and through 6/30/2010 may intermittently exhibit one or more of the following concerns; transmission slipping or neutral-out, 5th gear start from stop, backup camera on in Drive, or speed control dropping out or inoperative. This may be due to high resistance in the digital transmission range (TR) sensor.

ACTION:

Follow the Service Procedure steps to correct the concern.

SERVICE PROCEDURE

Check the TR sensor circuit resistance.

With brakes applied, engine off, key on, move the shifter to low gear (L or M) position.
Turn key off.
Disconnect connector C168 from the transmission.
Measure the resistance between the transmission connector pins:
- 8 and 4
- 8 and 5
- 8 and 6
- 8 and 7
1. The top row of the transmission’s pins are numbered 1-10 from left to right. (Figure 1)
  Figure 1 – Article 13-5-27
2. If any of the four measurements are above 5 Ohms, proceed to Step 5.
3. If all measurements are within specification, this article does not apply. Refer to the appropriate Workshop Manual (WSM) Section for diagnosis and repair.
Replace the TR sensor. Refer to the WSM, Section 307-01.
1. Use only essential special service tool (ESST) 307-696 to remove the retaining pin that holds the TR sensor in the transmission case.
2. Attach ESST 307-696 to the transmission case with two (2) pan bolts.
3. Slide the cylinder over the head of the retaining pin and tighten the nut on the threaded shaft to pull the cylinder up and retaining pin out of the transmission case. (Figure 2)
  Figure 2 – Article 13-5-27
4. Do not allow the park pawl actuator rod to become disengaged from the park pawl and the abutment. Keep the end of the park pawl actuator rod behind the machined valve body mating surface of the transaxle case. If the park pawl actuator rod becomes disengaged from the park pawl and the abutment, transaxle removal and disassembly is required to install the actuator rod. (Figure 3)
