P0741 on Toyota vehicles
Torque Converter Clutch Stuck Off — what it means on a Toyota, whether it's safe to drive, and the fixes by model and year.
P0741 on a Toyota means torque converter clutch stuck off. Most vehicles stay drivable short-term, but diagnose it promptly. The most common cause is worn or burned torque converter clutch friction material (typically $1,800–$4,500). Pick your Toyota model below for its known failure patterns, recalls, and TSBs.
What does P0741 mean on a Toyota?
P0741 is set when the ECM (or TCM) commands the torque converter clutch (TCC) to lock up under cruise conditions and does not see the expected drop in engine RPM relative to vehicle speed. Effectively, the lockup clutch is being commanded but not engaging — or it engages and immediately slips. Either way the converter is running in fluid-coupling mode at highway speed when it should be mechanically locked.
P0741 is a standardized OBD-II code, so its definition is the same on every Toyota. What differs by model and engine is which cause is most likely — pick your Toyota model below for a diagnosis tuned to its known failure patterns, recalls, and TSBs.
Is it safe to drive a Toyota with P0741?
In most cases a Toyota stays drivable for short trips with P0741 active, but diagnose and repair it promptly. This is a high-severity code — ignoring it can lead to further damage or a failed emissions test. Exact tolerance depends on the model and engine.
What causes P0741 on a Toyota?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|
| Worn or burned torque converter clutch friction material — Requires torque converter replacement — major job. | Most common | $1,800–$4,500 |
| Failed TCC solenoid in the valve body | Common | $300–$900 |
| Stuck TCC control valve in the valve body | Common | $400–$1,500 |
| Low transmission fluid level or contaminated fluid | Common | $100–$400 |
| Wiring fault to the TCC solenoid | Occasional | $80–$350 |
| Failed TCM driver for the TCC solenoid | Rare | $500–$1,500 |
| Internal transmission damage allowing fluid bypass | Occasional | $2,500–$6,500 |
Repair costs are typical US ranges and vary by Toyota model, model year, and labor rate. A diagnostic trouble code is a symptom, not a guaranteed failed part — confirm the root cause before replacing anything.

What are the symptoms of P0741 on a Toyota?
Check Engine Light is illuminated. Engine RPM at highway cruise is 200–400 RPM higher than normal. Noticeable fuel economy drop on the highway. Possible transmission fluid overheating warning on towing. Shudder or vibration at light-throttle cruise (slipping TCC). Often paired with P0700 from the TCM
What causes P0741 on a Toyota?
Worn or burned torque converter clutch friction material (most-common). Failed TCC solenoid in the valve body (common). Stuck TCC control valve in the valve body (common). Low transmission fluid level or contaminated fluid (common). Wiring fault to the TCC solenoid (occasional). Failed TCM driver for the TCC solenoid (rare). Internal transmission damage allowing fluid bypass (occasional)
