P0741
ModerateTorque Converter Clutch Circuit Performance/Stuck Off
P0741 is usually drivable, but the converter shudder and extra heat aren't good for the transmission long-term, and it occasionally causes stalling at stops. It's lower-urgency than a slipping-gear problem. Try a fluid service and the solenoid before anyone suggests a torque converter, which is a major job.
What this code means
At cruising speed an automatic transmission locks the torque converter clutch (TCC) to create a direct connection — it stops the slight slippage of the converter, which improves fuel economy and lowers heat. P0741 means that lock-up isn't happening properly (the clutch is slipping or stuck off). The cheaper, common causes are a failed TCC solenoid, or low/old/contaminated transmission fluid and a dirty valve body. The expensive cause is wear inside the torque converter itself. Because those outcomes are worlds apart in cost, this one really needs diagnosing before parts.
Symptoms you might notice
- Shudder or vibration at steady highway speed
- Engine RPM stays higher than normal at cruise (won't 'lock in')
- Slightly worse fuel economy and more transmission heat
- Occasional stalling when coming to a stop
- Check-engine light
What it costs to fix
Typical range: $100–$2,500 · about ~0.5–8 hrs of labor
| If the cause is… | Part | Labor |
|---|---|---|
| Transmission fluid & filter service | $80–$250 | ~0.5–1.5 hrs |
| TCC solenoid | $30–$150 | ~1–4 hrs |
Start with a fluid service and the TCC solenoid — the cheaper, common causes (though solenoid labor climbs if it's inside the transmission). A worn torque converter is the expensive end: replacing it means removing the transmission, which varies far too much by vehicle to quote and is why the upper range is left open.

How to fix P0741
Moderate — doable at home with common tools and patience
- Assess the fluid before any parts
Check level, color, and smell — old, dark, or burnt fluid interferes with the delicate pressure control the converter clutch needs, and a slipping TCC also burns fluid, so the fluid's condition is both a suspect and a witness. This check decides whether the story is hydraulic housekeeping or something more expensive.
- Service the fluid and filter if it's tired
Fresh fluid and a clean filter restore pressure and can free a varnish-sticky lockup circuit — it's the cheapest plausible fix for this code. If the code returns afterward, you've lost nothing: the transmission needed the service anyway.
- Measure TCC slip on a scan tool
At steady highway cruise, watch the TCC slip parameter (or compare engine RPM to input speed) when lockup is commanded. Slip near zero means lockup works and the fault is intermittent; persistent slip of dozens or hundreds of RPM confirms the clutch genuinely isn't holding.
- Test and replace the TCC solenoid
Check the solenoid's resistance and its wiring; on many transmissions it's accessible with the pan off, making it a reasonable repair. A solenoid that's electrically fine can still fail hydraulically, so replacement is often the practical test when everything else checks out.
- Torque converter replacement as the last resort
If fluid, solenoid, and valve-body checks all pass and the clutch still slips, the friction material inside the converter is worn — and the converter comes out only with the transmission. Get the earlier diagnosis confirmed before authorizing this, because it's the expensive branch of this code.
DIY or shop? The fluid assessment, the service, and scan-tool slip measurement are all achievable at home, and they settle the cheap-versus-expensive question before any money is committed. Dropping the pan for a solenoid is intermediate DIY on transmissions where the solenoid is reachable there. The moment the diagnosis points inside the converter, it's a transmission-removal job — pure shop territory — so the value of doing the early steps carefully is exactly to avoid paying for that when a fluid service would have done.

Frequently asked
Can I drive with P0741?
Usually yes, short-term — it mainly costs you fuel economy and lets the transmission run hotter, with some shudder at cruise. If it causes stalling at stops, be careful. Get it looked at before the heat does longer-term harm.
What's the cheapest thing to try for P0741?
A transmission fluid and filter service, plus testing the TCC solenoid. Old or contaminated fluid and a failing solenoid are common, far cheaper causes than the torque converter — worth ruling out first.
Do I need a new torque converter for P0741?
Not always — many P0741s are fixed by fresh fluid or a solenoid. The converter itself is the expensive cause and is confirmed only after the cheaper possibilities are ruled out, because replacing it means dropping the transmission.
How much does it cost to fix P0741?
From a modest fluid service or solenoid up to a major torque-converter job (which requires removing the transmission and varies widely by vehicle). Diagnose the cheap causes before committing to the converter.
