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%.
