Shift Malfunction

Understand P0780, common causes, and the right TOPDON scanner to diagnose it.

General shift malfunction — TCM detected abnormal shift event.

Vanliga symptom

  • Harsh or flare shifts
  • Trans warning

Typiska orsaker

  • Low ATF
  • Solenoid failure
  • Mechanical wear
  • Needs adaptation reset

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
