P0741 on Infiniti by model: symptoms, diagnosis and fix
The QX70's RE7R01A seven-speed automatic draws consistent owner complaints for delayed engagement when selecting drive or reverse, rough or clunky shifts between the lower gears, and a shudder felt during light acceleration at low speed. The transmission is generally durable, and most of these complaints trace to fluid condition and to the torque converter lock-up clutch rather than to hard parts: the factory positions the fluid as lifetime fill, which it is not, and degraded fluid makes the converter clutch chatter as it modulates. Left in service long enough, shudder that started as a fluid problem does become a converter problem.
Common Symptoms
- Delayed engagement when shifting into drive or reverse
- Rough or clunky shifts in the lower gears
- Shudder or vibration under light acceleration at low speed
- Flare or hesitation between gears
- Harsh downshift when coming to a stop
How to Fix
Start with the fluid, not with a rebuild quote. Have the transmission serviced with genuine Nissan Matic S — this transmission is specific about fluid and generic multi-vehicle ATF is a common cause of exactly these symptoms after an independent service. A drain-and-fill repeated two or three times at intervals is gentler than a high-pressure flush on a unit with high mileage. Have the shop check for stored transmission codes and confirm the torque converter clutch slip rate on a scan tool while driving, which distinguishes converter shudder from a hard-part fault. If delayed engagement persists on fresh correct fluid, the next suspects are the valve body solenoids and the accumulator, both far cheaper than a replacement unit. Ignore advice to add friction modifiers or shudder-fix additives — they mask the symptom while the fluid continues to degrade.

Frequently asked questions
What does P0741 mean on a Infiniti?
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 Infiniti it is documented across 1 model: QX70.
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 Infiniti?
Published repair estimates on Infiniti range from $300 to $3,500 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.
