P0741 Torque Converter Clutch Circuit Performance or Stuck Off

P0741 indicates torque converter clutch performance or stuck-off behavior. The controller commanded converter lockup but did not see the expected slip reduction.

Code details

Generic OBD-II · P0

System: Transmission
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not authorize converter replacement before checking solenoid control and hydraulic apply conditions; stuck-off behavior can be electrical or hydraulic.

Symptoms of P0741

Harsh, delayed, or slipping shifts, or being stuck in one gear.
Check-engine light, sometimes with limp-home mode.
Flaring RPM or a shudder under load.

Common causes of P0741

Low or degraded transmission fluid.
A failing speed sensor, shift solenoid, or pressure-control circuit.
Wiring, connector, or internal hydraulic/mechanical faults.

Useful checks before replacing parts

Compare commanded TCC state with actual slip RPM during steady cruise and light throttle.
Check fluid level, fluid condition, TCC solenoid operation, pressure-control data, wiring, and converter clutch apply conditions.
Review whether the fault is temperature-dependent or appears with other ratio, pressure, or solenoid codes.
