   Hi There, Diagnostic Trouble Code (DTC) P0741 or P1744 may be stored in memory. This may be caused by the Powertrain Control Module (PCM) unsuccessfully attempting to engage the torque converter clutch 5 consecutive times. The torque converter clutch may not engage if one or more of the following conditions exist: Stuck converter regulator valve Stuck solenoid regulator valve Stuck bypass clutch control valve Worn pump shaft or damaged seals Incorrect Torque Converter Clutch (TCC) solenoid Incorrect or damaged internal wiring harness Incorrect gear ratio ACTION: Refer to the following Diagnostic Procedure for details. DIAGNOSTIC PROCEDURE 1) For DTC P0741 and P1744, perform Pinpoint Test "C" and refer to Diagnostic Routines 240 and 340 in Section 07-01 of the appropriate Taurus/Sable or Continental Service Manual. 2) Remove the transaxle lower pan and check for excessive debris in the pan. 3) Remove the main control cover and main control. 4) Check for pump shaft wear or damaged seals. 5) Inspect the main control for a stuck converter regulator valve and solenoid regulator valve located in bore "A." Refer to Figure 1. 6) Inspect the bypass clutch control valve located in bore "D." Refer to Figure 1. 7) Clean the main control and make sure all valves move freely. Do not sand, stone, or file valves or bores in the main control. 8) Inspect for the correct TCC solenoid. Refer to TSB 97-13-12 for TCC resistance. 9) TCC resistance should be 0.98-1.6 ohms for 1996-97 Taurus/Sable and 1996 Continental; 13-24 ohms for 1998 Taurus/Sable and 1997-98 Continental. 10) If the transaxle has been exchanged, refer to TSB 97-23-7 .
