Gear 2 Incorrect Ratio

Understand P0732, common causes, and the right TOPDON scanner to diagnose it.

TCM detected second gear ratio does not match calculated value — slip or mechanical fault.

Veelvoorkomende symptomen

  • Slipping in 2nd
  • Trans fault
  • Harsh downshift

Typische oorzaken

  • Low ATF
  • Worn clutch packs
  • Failed solenoid
  • Internal band issue

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
