P0741 on Kia
Torque Converter Clutch Circuit Performance/Stuck Off
P0741 on Kia vehicles indicates torque converter clutch circuit performance/stuck off. Au7o has documented this code across 7 Kia models — most commonly on Amanti, K5, Niro. 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 Kia range from $150 to $6,500, 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)
P0741 on Kia by Model
Kia Amanti(1 issue)
- Automatic Transmission Failure (5-Speed)2004-2009
The 5-speed automatic transmission in the Kia Amanti is prone to premature failure, particularly affecting the torque converter, forward clutch pack, and valve body. The transmission was shared with the Hyundai XG350 platform and struggles with the 3.5L V6 engine torque output. Symptoms progress from harsh shifting to slipping to complete failure, typically between 80,000-120,000 miles. Regular ATF changes can extend life, but the transmission design has inherent durability limitations.
Kia K5(1 issue)
- 8-Speed DCT Electric Oil Pump Failure2021-2023
K5 vehicles equipped with the 2.5L turbocharged engine and 8-speed wet dual-clutch transmission may experience electric oil pump failure within the transmission. A manufacturing error can cause the pump to fail, resulting in complete loss of vehicle power while driving. This creates a serious safety hazard, particularly at highway speeds.
Kia Niro(1 issue)
- Dual-Clutch Transmission Judder (Hybrid)2017-2022
The 6-speed dual-clutch transmission (DCT) in the 1st generation Niro Hybrid (2017-2022) develops a juddering or shaking sensation when starting from a stop and during low-speed gear changes. The dry clutch pack wears and develops uneven friction surfaces, causing the shudder. This is most noticeable in stop-and-go traffic and typically appears between 25,000-40,000 miles. The issue is exacerbated by the frequent clutch engagement/disengagement required by the hybrid system.
Kia Optima(1 issue)
- 7-Speed DCT Transmission Clutch Judder2016-2020
Vehicles equipped with the 1.6L turbocharged engine and 7-speed Dual Clutch Transmission (DCT) may experience clutch judder, causing vibration and jerking during low-speed acceleration and when starting from a stop. The issue is particularly noticeable during cold starts and in stop-and-go traffic.
Kia Sedona(1 issue)
- Automatic Transmission Shudder and Harsh Shifting2015-2021
The 2015-2021 Sedona with the 6-speed automatic transmission develops shuddering during gear changes, harsh shifts, and delayed engagement. The torque converter lock-up clutch wears prematurely, and the transmission valve body develops stuck solenoids. Kia released multiple TCU software updates to improve shift quality. In severe cases, torque converter or complete transmission replacement is needed.
Kia Sorento(1 issue)
- DCT Transmission Oil Pump Failure (2.5T)2021-2022
The 2021-2022 Sorento with the 2.5L turbo engine and 8-speed dual-clutch transmission (DCT) can experience transmission oil pump failure due to a supplier production defect. The failed oil pump starves the transmission of lubrication, leading to sudden loss of drive power. NHTSA Recall 22V-826 covers approximately 65,000 Sorentos. Kia dealers inspect and replace the transmission if the oil pump is defective, plus reprogram the TCU with updated software.
Kia Stinger(1 issue)
- 8-Speed DCT Harsh Shifting and Delayed Response2018-2023
The 8-speed wet dual-clutch transmission in the Stinger exhibits harsh low-speed shifts, delayed response when pulling away from stops, and occasional gear hunting on hills. The DCT clutch pack adapts over time but the adaptive learning can drift, leading to rough shifts. TCU software updates have improved shift quality. In rare cases, clutch pack replacement is needed.

What does P0741 mean on Kia?▼
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 Kia specifically, this code is documented across 7 models.
What causes P0741 on Kia vehicles?▼
Common causes on Kia: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0741 on a Kia?▼
Repair costs on Kia range from $150 to $6,500, depending on the specific model and root cause.
