P0741 on Pontiac

Torque Converter Clutch Circuit Performance/Stuck Off

Moderate1 Pontiac model affectedSystem: Transmission

P0741 on Pontiac vehicles indicates torque converter clutch circuit performance/stuck off. Au7o has documented this code across 1 Pontiac model — most commonly on Grand Prix. 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)

  • 4T65-E Automatic Transmission Hard Shifting and Failure2001-2008

    The exact corpus supports 4T65-E shift and failure conditions throughout the frozen 2001-2008 range, but not one cause. Examples include P0756/P0757 shift faults, P0741/P0742 TCC paths, pressure-control and valve-body work, second-clutch shudder, V8 torque-converter conditions, slips/no drive/reverse and code-specific valve-body reconditioning (including 10025065 for 2001-2008). The frozen accumulator, clutch-pack, solenoid and pan-magnet explanation collapses distinct unit/RPO, calibration, hydraulic, electrical and mechanical paths.

Frequently Asked Questions

What does P0741 mean on Pontiac?▼

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 Pontiac specifically, this code is documented across 1 model.

What causes P0741 on Pontiac vehicles?▼

Common causes on Pontiac: 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 Pontiac?▼

Repair costs vary widely depending on the root cause and specific Pontiac model.
