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.

Sintomi comuni

  • Slipping in 2nd
  • Trans fault
  • Harsh downshift

Cause tipiche

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

Di quale scanner hai bisogno?

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

Usa dati live e freeze frame prima di sostituire componenti. I codici ABS, SRS e U richiedono di solito uno scanner full-system.

Consigli diagnostici

  • Registra il freeze frame quando compare il codice
  • Cancella il codice solo dopo aver risolto la causa
  • Controlla codici pending correlati
  • Verifica che la batteria sia sopra 12,4 V prima di sospettare i sensori
