This article supersedes TSB 07-3-11 to update the transaxle built date coverage and Part List.

ISSUE
Some 2007-2008 Edge and MKX, 2008 Taurus Taurus X, and Sable vehicles equipped with a 6F50 transaxle with a build date prior to 10/21/2007, with any Output Shaft Speed (OSS) sensor or Turbine Shaft Speed (TSS) sensor diagnostic trouble code(s) (DTCs) P0715, P0717, P0718, P0720, P0721, P0722 and/or harsh engagements, no upshift, fifth gear only, could have an intermittent short in the OSS or TSS sensor.

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

1. If any DTCs related to OSS or TSS are present, check the transaxle build date following Workshop Manual (WSM), Section 307-01.

a. If the build date is before 10/21/2007 go to Step 2.

b. If vehicle transaxle is built on or after 10/21/2007 do not continue with this TSB and follow normal WSM, Section 307-01 Automatic Transaxle/Transmission-6F50 Diagnosis and Testing.











2. To repair an OSS or TSS DTC refer to WSM, Section 307-01, follow pin point test (PPT) C. The TSS sensor is located in the end cover assembly (Figure 1). The OSS sensor is located inside the transaxle under the main Control (Figure 2). Both sensor connectors are plugged into the solenoid body. Both sensor connectors look the same but are wired differently (Figure 3).

3. If you work through PPT C and get to Step C9 before finding the cause of the concern, replace the sensor (DO NOT REPLACE THE POWERTRAIN CONTROL MODULE (PCM) AT THIS TIME). Reassemble as needed and verify the concern is fixed.
