Where P0740 shows up
Source: NHTSA manufacturer communications and complaintsShowing the 60 model years where P0740 appears most; it is on file for 142 in total.
A model year appears here because the code is named in its record, not because every one of these vehicles sets it. Counts are mentions in the federal files, not failure rates — nobody publishes the denominator.

What owners said

Diagnostic trouble codes retrieved: P0740 (Torque Converter Clutch Actuator Stuck On), P0745 (Pressure Control Solenoid A Stuck Off), and P2713 (Pressure Control Solenoid D Stuck Off)
The vehicle was taken to a local dealer where it was diagnosed with codes HAF, DTC, P0740, TCC clutch performance, and metal debris found in the transmission fluid

What P0740 means
Source: SAE J2012 / OBD-IIA fault in the torque converter clutch circuit.
A stored code names the test that failed, never the part that caused it. It is the starting point of a diagnosis, not its conclusion — the same code has several possible causes and the cheap one is not always right.
Common questions about P0740
Source: NHTSA files and the OBD-II standardCan I keep driving with P0740 stored?
Nobody can answer that from the code alone, and a site that does is guessing. A steady light generally means the fault was logged and the vehicle is in a reduced-risk mode; a flashing light means stop soon, because a misfiring engine can destroy a catalytic converter in minutes. The safe read of this page is the mileage and the components, not permission.
Does a code mean the car is recalled?
No. Recalls are filed by campaign and matched by VIN, and none of them are triggered by a scan tool. If you want to know whether an open recall applies to one specific vehicle, check the VIN at nhtsa.gov/recalls — that is the only source that settles it.
Why do the counts here differ from other sites?
Because these are not estimates. Every number on this page is a count of documents in NHTSA's own files: manufacturer communications that name the code in their filed summary, and owner complaints that name it in the narrative. We do not model, weight or extrapolate them.
Will clearing the code fix it?
Clearing turns the light off and erases the freeze-frame data a technician would have used to work out what happened. If the condition is still there the code returns, usually within a few drive cycles, and the diagnosis now starts from less information than before.
