Number P0741: Torque Converter Clutch Circuit Performance/Stuck Off
P0741 means the converter clutch does not lock although commanded – slip stays too high while the circuit is electrically fine. Thresholds: GM's T43 at least 130 rpm for 5 s twice, the 6T70 50 rpm for 5 s three times, Saab's Aisin AF40 over 100 rpm for 2 s, all after two trips; Ford over 100–200 rpm
Can you drive with P0741?
Severity: Fix promptly — drivability fault. Short trips at moderate speed only. If the car has entered limp mode (won't rev, stuck in one gear), have it towed rather than forcing it.
If you ignore it: Limp-mode faults tend to strand you, and several of them (misfires, throttle faults) damage other parts while you wait.
This is the #48 most common code in our top-150 library, in the transmission family (Powertrain system). Severity is Number Nest's editorial triage — if the light is flashing or the car feels unsafe, stop driving it whatever any page says.
What P0741 means
P0741 means the converter clutch does not lock although commanded – slip stays too high while the circuit is electrically fine. Thresholds: GM's T43 at least 130 rpm for 5 s twice, the 6T70 50 rpm for 5 s three times, Saab's Aisin AF40 over 100 rpm for 2 s, all after two trips; Ford over 100–200 rpm or a speed ratio below 0.93 over five lock-up events; Subaru engine speed more than 9/8 of target for 10.2 s. The module then locks out the clutch, sometimes the top gear, and uses a hot-mode shift pattern. Low or burnt fluid, a worn control valve in the valve body and a glazed converter clutch are the usual causes; Hyundai's 8-speed bulletin calls for a new converter.
Systems involved: torque converter clutch solenoid, torque converter, transmission valve body, transmission control module.
Causes, ranked by likelihood
| # | Cause | Likelihood |
|---|---|---|
| 1 | Fluid level too low, old or burnt fluid | most likely |
| 2 | Converter clutch control valve worn or sticking, bore worn | most likely |
| 3 | Lock-up clutch in the converter worn or glazed | possible |
| 4 | Solenoid mechanically sluggish (electrically fine) | possible |
| 5 | Leaking turbine shaft seals or pump | less common |
Check them in order — the list is ranked so the likely, cheaper causes come before the expensive part.
Symptoms you may notice
- Check engine light or transmission warning
- Higher engine speed when cruising, 'rubber band' feel
- Higher consumption, rising fluid temperature
- Possibly shudder when the clutch applies
Misdiagnosis traps
- Replacing the part named by the code title without testing. The code reports a failed self-test; the cause list above is ranked so the likely, cheap causes are checked before the expensive part is condemned.
- Clearing the code and declaring victory when the light stays off for a day — the monitor that sets this code runs only under specific driving conditions.
(General diagnostic guidance for this code family — no code-specific trap is published for this code.)
How a good shop confirms it
- Confirm the code and record any companion codes — companions narrow the system fast.
- Inspect the affected components and their wiring/connectors for damage, corrosion and looseness.
- Test the top-ranked cause with live data or a multimeter before replacing anything.

Frequently asked questions
How much does it cost to fix P0741?
The fix most associated with this code — transmission shift solenoid — runs $338 – $838 at an independent shop for a midsize car in our cost model (parts + labor, US average). The code names a system, not a part, so confirm the cause before spending: the ranked causes above are ordered by likelihood.
Can I drive with P0741?
See the can-you-drive verdict above — it is based on the system involved and the cascading-damage risk, and it is our editorial triage, not a manufacturer instruction. If the light is flashing or the car feels unsafe, stop driving it regardless of any code.
Will P0741 clear itself?
If the fault was a one-off (a loose cap, a cold-start glitch), the light can go out after several clean trips and the code ages into history. A fault that is still present re-sets the code as soon as the car runs that self-test again — monitors run under specific conditions, which is why "it hasn't come back in two days" is not proof of a fix.
Will my car fail inspection with P0741?
In states with OBD-based emissions inspection, yes — an illuminated check-engine light or an incomplete readiness monitor fails the test regardless of what the tailpipe would show. C-codes (ABS) fall under safety inspection instead in states that have one.
What should I check first for P0741?
The first item on the ranked-causes list above — it is ranked likelihood-first for exactly this reason — plus the free checks: recent work in the area (connectors left loose are a classic), fluid levels, and the battery and grounds on electrical codes.
Where this data comes from
Code facts, causes and symptoms come from OBDex — an open dataset of independently authored descriptions of the standardized generic OBD-II codes (CC0 1.0, public domain; github.com/foerbsnavi/OBDex). The SAE J2012 document itself is copyrighted and is not reproduced here. Cost ranges are Number Nest's own US planning model: national parts and labor ranges cross-checked against the CarMD Vehicle Health Index 2026 published averages, with labor adjustable by the BLS OEWS May 2025 state wage index for auto technicians (occupation 49-3023) — a wage index, not a surveyed shop rate.
