DTC
Description
Possible Cause
Action
P074100 Torque Converter
Clutch Solenoid
Circuit
Performance/Stuck Off
High contact resistance in the
connector terminals
Open circuit of SLU circuit of
lock up control solenoid
Failure of SLU lock up solenoid
SLU lock up solenoid stuck in
closed position
Internal failure in TCM
Check for high contact resistance in the connector terminals between
the TCM and transmission. Suspect the TCM, check and install a new
TCM as required, refer to the new module/component installation note
at the top of the DTC Index. Suspect the transmission, check and
install a new transmission as required, refer to the new
module/component installation note at the top of the DTC Index.
Refer to service routines at the top of the DTC Index and carry out
service routines as required using the manufacturer approved
diagnostic system
