P0741 on Mercury
Torque Converter Clutch Circuit Performance/Stuck Off
P0741 on Mercury vehicles indicates torque converter clutch circuit performance/stuck off. Au7o has documented this code across 1 Mercury model — most commonly on Cougar. 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.
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 Mercury by Model
Mercury Cougar(1 issue)
- CD4E Automatic Transmission Failure (8th Gen)1999-2002
NHTSA communications establish several distinct CD4E conditions on 1999-2002 Cougar vehicles: no-forward engagement in 605229 and 6091763, 1999 ring-gear side loading of the forward-clutch snap-ring retainer in 607645, intermittent loss of first and second gears with P0758 or P0740 in 619324, and harsh or delayed shifts after speed-sensor service in 630631. These records support the generic CD4E problem identity but not one universal valve-body or drum cause.

What does P0741 mean on Mercury?▼
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 Mercury specifically, this code is documented across 1 model.
What causes P0741 on Mercury vehicles?▼
Common causes on Mercury: 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 Mercury?▼
Repair costs vary widely depending on the root cause and specific Mercury model.
Which Mercury models have P0741 documented?▼
