CD4E - ENGINE STALLING ON ENGAGEMENT/STOPPING

FORD:
2005-2008 Escape

MERCURY:
2005-2008 Mariner

ISSUE
Some 2005-2008 Escape and Mariner vehicles equipped with a CD4E automatic transaxle and built from 8/1/2004 through 2/15/2007 may exhibit an engine stall when coming to a stop or when engaging the transmission into drive or reverse. This condition may be intermittent and often occurs after extended drives. There may be no diagnostic trouble codes (DTCs) stored. This may be caused by internal wear in the torque converter which prevents it from unlocking.

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE
1. Inspect and repair all non transaxle codes per Workshop Manual (WSM) and Powertrain Controls/Emissions Diagnosis (PC/ED) manuals.

2. Use the Integrated Diagnostic System equipment to monitor the PIDs (Parameter Identification) for TC_SLIPACT as the stall is occurring.
a. If the slip is greater than 20 RPM, the stalling is not transaxle related. Repair following PC/ED procedures for engine stalling condition.
b. If TC_SLIPACT is less than 20 RPM with the transmission in park or neutral, torque converter internal failure is the most likely cause, proceed to Step 3.

3. Remove the transaxle assembly and check the rotation of the torque converter in the bell housing. A failed converter will be difficult to rotate.

4. Remove the torque converter, drain the automatic transmission fluid (ATF) and refill the CD4E transmission assembly using MERCON(R) V ATF.

5. Install a new torque converter and reinstall the transaxle assembly.

6. Back flush the transmission cooler system as described in the WSM, Section 307-01A.

2005-2006 AND 2008 TRIBUTE - ENGINE STALLS ON ENGAGEMENT / STOPPING

APPLICABLE MODEL(S)/VINS
2005-2006 and 2008 Tribute vehicles equipped with Automatic Transaxle (ATX) built from Aug. 1, 2004 to Feb. 15, 2007

DESCRIPTION
Some vehicles may exhibit an engine stall when coming to a stop or when engaging the ATX into drive or reverse. This condition may be intermittent, and often occurs after extended drives. There may be no diagnostic trouble codes (DTCs) stored. This concern may be caused by internal wear of the torque converter, which prevents it from unlocking. A modified torque converter is available.

Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE
1. Verify customer concern.

2. Check automatic transmission fluid (ATF) level and add if necessary.

3. Inspect and repair all non-transaxle codes according to Workshop Manual.

4. Use M-MDS to monitor PIDs (Parameter Identification) for TCSLIPACT as stall occurs.
^ If slip is greater than 20 RPM, stalling is not transaxle related. Repair according to Workshop Manual procedure for engine stalling.
^ If there is less than a 20 RPM difference between the two, torque converter clutch (TCC) internal failure is the most likely cause. Proceed to Step 5.

5. Raise vehicle safely on hoist.

6. Drain automatic transmission fluid (ATF) from transaxle assembly.

7. Remove automatic transaxle assembly according to Workshop Manual (section 05-13 TRANSAXLE - 3.0L (4V) or TRANSAXLE - 2.3L).
NOTE:
Check the rotation of the torque converter in the bell housing. A failed torque converter will be difficult to rotate.

8. Remove torque converter from bell housing.

9. Install new torque converter and reinstall automatic transaxle assembly according to Workshop Manual (section 05-13 TRANSAXLE - 3.0L (4V) or TRANSAXLE - 2.3L).

10. Refill automatic transaxle assembly with MERCON(R)V ATF.

11. Back-flush transaxle cooler system according to Workshop Manual (section 05-13 TRANSAXLE FLUID COOLER - BACKFLUSHING AND CLEANING).

12. Inspect for proper ATF level.

13. Verify repair.
