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.

Veelvoorkomende symptomen

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

Typische oorzaken

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

Welke scanner heb je nodig?

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

Gebruik live data en freeze frame voordat je onderdelen vervangt. ABS-, SRS- en U-codes vereisen meestal een full-system scanner.

Diagnosetips

  • Leg freeze frame vast wanneer de code voor het eerst verschijnt
  • Wis de code pas na het oplossen van de oorzaak
  • Controleer op gerelateerde pending codes
  • Controleer of accuspanning boven 12,4 V is voordat je sensoren suspecteert
