P0741 on Subaru by model: symptoms, diagnosis and fix
P0741 sets when the ECM/TCM commands the torque converter clutch to lock up but the expected reduction in converter slip doesn't happen. On the older automatic-transmission Outbacks (4EAT on 2005-2009 2.5i, 5EAT on 3.0R and 3.6R; 2010-2014 2.5i automatics use the Lineartronic CVT and are not covered by this description) the dominant real-world causes are a failed torque-converter-clutch (lockup) solenoid on the valve body, a poor ground on the transmission harness, or dark/burnt/contaminated ATF and debris blocking fluid flow to the converter. It is frequently misdiagnosed: shops assume the converter itself is bad and quote a transmission-out job, when the actual fault is a cheap solenoid, a bad ground, or fluid that was never serviced. Neglected fluid is the common thread on high-mileage cars.
Common Symptoms
- Check engine light
- Torque converter shudder or vibration at cruise
- Harsh or delayed lockup
- Slightly higher RPM at highway speed
- Possible reduced fuel economy
How to Fix
Check ATF level and condition first — if burnt or contaminated, do a proper fluid/filter service. Inspect and clean the transmission harness ground and the TCC solenoid connector for corrosion or looseness. Test the lockup solenoid; replace it (on the valve body) if it fails. Only pull the transmission for the torque converter if the solenoid tests good AND there is confirmed shudder/noise — do not replace the converter blindly.

Frequently asked questions
What does P0741 mean on a Subaru?
P0741 stands for "Torque Converter Clutch Circuit Performance/Stuck Off." This code means the torque converter clutch (TCC) is not working as expected and is effectively stuck off, so the converter clutch isn't locking up the way the computer commands it to. The TCC mechanically links the engine to the transmission at cruising speeds to reduce slippage and improve fuel economy, and the computer compares engine RPM to transmission/output speed to verify lockup. When the expected RPM drop from lockup doesn't happen, it sets this performance code. You may notice higher-than-normal RPM at highway speed, reduced fuel economy, and sometimes elevated transmission temperatures. On Subaru it is documented across 1 model: Outback.
What are the most common causes of P0741?
The most common causes of P0741 are: Low, dirty, or degraded transmission fluid, Faulty torque converter clutch (TCC) solenoid, Stuck or worn valve body / TCC control valve, Failed torque converter (internal clutch worn or slipping), Internal transmission leaks reducing apply pressure, Damaged wiring or connector to the TCC solenoid, Faulty transmission control module (TCM/PCM). The specific cause varies by vehicle.
How much does it cost to fix P0741 on a Subaru?
Published repair estimates on Subaru range from $150 to $1,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
