Error Code P0741: What It Means & What To Do?
OBD Code P0741 - Torque Converter Clutch Circuit Performance or Stuck Off
If
your vehicle has the error code P0741 stored, don’t panic. We will provide you
with all the information needed to understand, diagnose and solve this OBD-II
code. This code is defined as a Torque Converter Clutch Circuit Performance or
Stuck Off. It is set by the Powertrain Control Module of the vehicle or PCM.
When
the PCM noticed a difference between rotational speed of the Torque convertor
and Transmission Input shaft which is greater than 200 RPM, it will proceed to
set this code. Typically, when the Torque Converter Lockup Clutch engages there
has to be a 1:1 ratio between the converter RPM and the Input Shaft RPM.
Discrepancies found in this will lead to this error code.

As
mentioned above the PCM sets this P0741 diagnostic trouble code when it
observes a faulty difference between the rotational speed of the torque
converter and the transmission input shaft which is greater than 200
revolutions per minute (RPM).
The
speed should normally be equal between the torque converter and the
transmission shaft, when the torque converter lockup engine engages. In the
situation where they’re not equal and the desired 1:1 ratio is not present, the
PCM will proceed to set error code P0741. This will be set as an indication
that the torque converter clutch circuit has malfunctioned or has gotten stuck.
