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.

Vanliga symptom

  • Slipping in 2nd
  • Trans fault
  • Harsh downshift

Typiska orsaker

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

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
