P0741 on Lexus
Torque Converter Clutch Circuit Performance/Stuck Off
P0741 on Lexus vehicles indicates torque converter clutch circuit performance/stuck off. Au7o has documented this code across 1 Lexus model — most commonly on RX. 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. Typical repair costs on Lexus range from $200 to $3,000, depending on the specific model and root cause.
Common Causes of P0741
- •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)

- 8-Speed Automatic Transmission Shudder2016-2022
The Aisin 8-speed automatic in the fourth-generation RX develops a noticeable shudder or vibration during light throttle acceleration, particularly in the 25-45 MPH range during torque converter lockup. The shudder is caused by torque converter clutch material wearing into the transmission fluid, degrading its friction properties.

What does P0741 mean on Lexus?▼
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.
