P0741 on Cadillac
Torque Converter Clutch Circuit Performance/Stuck Off
P0741 on Cadillac vehicles indicates torque converter clutch circuit performance/stuck off. Au7o has documented this code across 4 Cadillac models — most commonly on CT5, Escalade, STS. 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 Cadillac range from $200 to $4,500, 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 Cadillac by Model
Cadillac CT5(1 issue)
- 10-Speed Transmission Adaptive Learning and Shift Quality2020-2025
The CT5 uses GM's 10-speed automatic (10L80) that can exhibit harsh shifts, delayed engagement, and shift hunting, particularly when the adaptive learning resets. The 10-speed has very complex shift logic and can take 500+ miles to fully adapt to a driver's pattern after a battery disconnect, TCM update, or reset. Some CT5 owners report persistent shift quality issues even after adaptation. The CT5-V and CT5-V Blackwing have refined calibrations but can still exhibit occasional harsh shifts.
Cadillac Escalade(2 issues)
- 10L80 Transmission Harsh Shifting and Shudder2021-2025
The 5th generation Escalade (2021+) uses the GM 10L80 10-speed automatic transmission. While improved over the 8L90, some owners report harsh shifting, shudder at light throttle, and delayed shifts. The 10-speed has numerous clutch packs and a complex valve body with frequent adaptive learning resets needed. Some units develop torque converter shudder similar to the 8L90 issue. GM has released multiple TCM software updates to address shift quality. The issue is less prevalent than the 8L90 but still documented.
- 8L90 Transmission Shudder and Harsh Shifting2015-2020
The 2015-2020 Escalade uses the GM 8L90 8-speed automatic transmission that suffers from a widespread torque converter shudder issue. The shudder typically occurs at light throttle between 25-50 mph and feels like driving over rumble strips. The root cause is the torque converter clutch wearing prematurely, contaminating the transmission fluid with clutch material. GM extended the warranty and released updated torque converters and fluid, but many owners still experience the issue after the fix. This was the subject of a class action lawsuit.
Cadillac STS(1 issue)
- 6L50 6-Speed Automatic Transmission Overheating and Harsh Shifts2005-2011
The GM 6L50 6-speed automatic transmission in V6-equipped STS models is prone to overheating and developing harsh shift quality. The transmission fluid cooler is undersized for the vehicle weight, and the valve body solenoids degrade from heat cycling. Fluid darkens rapidly, and shift quality deteriorates with delayed or slipping 3-4 and 5-6 upshifts. The torque converter clutch also fails prematurely from heat damage.
Cadillac XT5(1 issue)
- 8-Speed / 9-Speed Transmission Shudder and Harsh Shifting2017-2025
The Cadillac XT5 uses an 8-speed (2017-2019) or 9-speed (2020+) automatic transmission. The 8-speed shares the torque converter shudder issue with other GM 8-speed vehicles. The 9-speed (GM 9T50/9T65) can have harsh shifts, delayed engagement, and shift hunting. Both transmissions have been subject to multiple software calibration updates from GM. The 9-speed is particularly sensitive to fluid condition and requires proper Dexron HP fluid.

What does P0741 mean on Cadillac?▼
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 Cadillac specifically, this code is documented across 4 models.
What causes P0741 on Cadillac vehicles?▼
Common causes on Cadillac: 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 Cadillac?▼
Repair costs on Cadillac range from $200 to $4,500, depending on the specific model and root cause.
Which Cadillac models have P0741 documented?▼
Au7o has documented P0741 on 4 Cadillac models: CT5, Escalade, STS, XT5.
