ISSUE
A flashing Overdrive (O/D) light with Diagnostic Trouble Codes (DTCs) P0741 and/or P1740 may be evident. Torque Converter Clutch (TCC) solenoid
lot numbers 769 and 771 may have damaged crimping points on the pintle. This allows the disc to move, causing the TCC solenoid to malfunction.
ACTION
Perform normal diagnostics and inspect the TCC solenoid for lot number 769 or 771, broken crimping points, movement of the pintle and/or a broken
TCC solenoid bracket. If any of these concerns are present, replace the TCC solenoid. New parts outside of lot number 769 or 771 do not have the
crimping point damage concern. Refer to the following Service Procedure for details.
SERVICE PROCEDURE

1.
Perform normal diagnostics.
2.
If the O/D light is flashing and DTC P0741 and/or P1740 is present, remove and inspect the TCC solenoid.
