What this usually means
This is 70% likely to be a 9G-Tronic conductor plate ($800-1,200) at 80-100k km. The 9-speed has a known wiring fault that mimics gearbox failure. Agent often quotes full transmission rebuild at $5k+. Insist on Star Diagnostic fault code readout BEFORE any teardown — 9G-Tronic faults are conductor-plate-specific, not torque-converter.
What to ask the workshop before approving repair
- • Show the diagnostic fault codes.
- • Show photo/video proof of the failed part.
- • Give an itemised quote for parts and labour.
- • Explain why cheaper common fixes were ruled out.
This is not a final diagnosis. It is a money-saving checklist before you go workshop.
