Torque Converter Clutch Circuit Performance

Understand P0741, common causes, and the right TOPDON scanner to diagnose it.

Torque converter lockup clutch not engaging as expected — shudder at highway speed or reduced fuel economy.

Vanliga symptom

  • Shudder ~45–55 mph
  • Poor highway MPG
  • Check engine light

Typiska orsaker

  • Failed TCC solenoid
  • Low fluid
  • Worn torque converter
  • Contaminated ATF

Vilken scanner behöver du?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Använd live-data och freeze frame innan du byter delar. ABS-, SRS- och U-koder kräver oftast en fullsystems-scanner.

Diagnostiktips

  • Spara freeze frame när koden först sätts
  • Rensa koden först efter att orsaken är åtgärdad
  • Kontrollera relaterade väntande koder
  • Verifiera batterispänning över 12,4 V innan du misstänker sensorer
