FORD: LINCOLN: MERCURY: 2005-2010 Crown Victoria 2005-2006 Expedition 2005-2010 E-150, E-250, E-350, F-150 2005-2010 Town Car 2006-2008 Mark LT 2005-2010 Grand Marquis Some 2005-2010 vehicles equipped with a 4R70/75E-W transmission may experience an un-commanded torque converter clutch (TCC) apply or TCC partial apply immediately after the 1-2 shift. This may result in the perception that the vehicle lacks power or that the transmission is up-shifting too early. Additional symptoms of uncommanded TCC apply when coming to a stop (before the 2-1 downshift is commanded), are engine stalling or lugging when engaging manual 2nd while at a stop and code P1742 may be present in continuous memory. However, the vehicle should operate normally in park, reverse, neutral and manual 1st gear. ACTION: Follow the Service Procedure for verification and repair. SERVICE PROCEDURE 1. Monitor (TCC %) solenoid command state – duty cycle and (TC SLIP ACT) torque converter clutch slippage – RPM, while in 2nd, 3rd or 4th gear with a TCC % reading 0. a. If TCC % = 0 and TC SLIP ACT = less than 20 RPM then inspect the number 7 check ball in the main control valve body for damage. Replace as required following the appropriate Workshop Manual (WSM) under Disassembly and Assembly of Subassemblies – Main Control Valve Body. (Figure 1) NOTE: THIS PROCEDURE IS PERFORMED IN 2ND GEAR AUTO (NOT MANUAL 2). MONITOR (TC SLIP ACT) AFTER THE POWERTRAIN CONTROL MODULE (PCM) COMMANDS 2ND GEAR AND BEFORE THE VEHICLE SPEED SENSOR (VSS) READS 35 MPH (56 KM/H). b. If you receive any other reading, this procedure does not apply; follow normal diagnostic procedures as outlined in the appropriate WSM. NOTE: IT IS NORMAL FOR THE PCM TO COMMAND 4TH GEAR AT SPEEDS AS LOW AS 19 MPH ( 30 KM/H) WITH LIGHT ACCELERATION WHEN THE THROTTLE POSITION IS LESS THEN 20%.

1. To check system operation, turn ignition on. Depress release button on side of gearshift lever. 2. With brake pedal released, gearshift lever should not move from Park. Depress brake pedal. With release button depressed, gearshift lever should now move from Park. 3. If shift lock system operation is not as specified, check brakelight switch and shift lock solenoid. See BRAKELIGHT SWITCH and SHIFT LOCK SOLENOID under COMPONENT TESTS. If necessary, check wiring and ground connections. See WIRING DIAGRAMS . KEY LOCK SYSTEM 1. With gearshift lever in any gear except Park, ensure ignition key cannot be turned to LOCK position. Place gearshift lever in Park. Ensure ignition key can now be turned to LOCK position. 2. If key lock system operation is not as specified, check key lock solenoid. See KEY LOCK SOLENOID under COMPONENT TESTS. If necessary, check wiring and ground connections. See WIRING DIAGRAMS .

Typically, the throttle plate angle parameter is 12-20% at time of condition with vehicle speed of approximately 24-40 km/h (15-25 mph). The customer may describe the condition as slip or delayed shift into second. Correction Replace the complete second clutch assembly with service kit, P/N 24240561. Refer to the GM Unit Repair Service Manual for the year and model of the vehicle being serviced for the 2nd Clutch service procedure. This service kit contains: Second Clutch Housing Fluid Seal Rings (613), a Second Clutch Assembly (617), a Case Cover (Channel Plate) Upper Gasket (430), and a Case Cover (Channel Plate) Lower Gasket (429).

Automatic Transaxle 2-3 Shift Flare During First Minutes of Driving After Cold Soak (Perform Bulletin Procedure) Models: 2002 Saturn S-Series Vehicles with Automatic Transaxle (RPOs MP6, MP7) Attention: General Manager, Fixed Operations Manager, Parts Manager, Technician Condition: Some customers of 2002 S-series vehicles with MP6 or MP7 automatic transaxles may comment on a 2-3 shift flare during the first few minutes of driving after vehicle cold soak. Cause: This condition may be caused by improper pressure, a leak in the 2nd clutch circuit, improper clutch plate finish on 2nd and 3rd clutches, a restriction in the 3rd clutch oil delivery path in the end cover, or improper surface finish in the piston bores of the 2-3 clutch housing. Correction: To correct this condition, duplicate by cold soaking the vehicle the amount of time at temperature described by the owner. Refer to procedure in this bulletin. Service Procedure Verify proper transaxle pressures by installing gauge and performing stepped pressure test after cold soak. Refer to “Stepped Pressure Test” procedure in the 2002 Saturn S-Series Automatic Transaxle Service Manual. ^ If pressures are low, follow the diagnostic chart for DTC P0745 for possible causes of low pressure. Refer to “P0745 – PC Solenoid Pressure Low” diagnostic in the 2002 Saturn S-Series Automatic Transaxle Service Manual. ^ If pressures are within normal ranges, proceed to Step 2. Remove the transaxle end cover. Refer to “End Cover Replacement” in the 2002 Saturn S-Series Automatic Transaxle Service Manual. Check torque on input shaft nut and end cover 3rd clutch oil passage for restrictions. ^ Input shaft nut torque should be 150 N.m (111 ft-lb). If nut is found to be loose, remove nut, clean threads and install new nut using Service Manual procedures and proceed to check 3rd oil passage. ^ Check 3rd oil passage in the end cover by pouring transaxle fluid through it and another passage. If the passage is restricted, you will notice significantly less fluid flow through it. If 3rd clutch passage is found to be restricted, install new end cover per Service Manual procedures and retest for concern. ^ If nut and 3rd clutch passage are okay, proceed to Step 4. Remove transaxle from vehicle. Refer to “Transaxle Removal” in the 2002 Saturn S-Series Automatic Transaxle Service Manual. Disassemble transaxle and install new 2-3 clutch housing, clutch pistons and clutch plates. Refer to “Transaxle Disassemble” in the 2002 Saturn S-Series Automatic Transaxle Service Manual.
