Comparison
| Option | Best for | Cost |
|---|---|---|
| TCM repair | Confirmed board fault | Low |
| Valve body repair | Solenoid or hydraulic fault | Mid |
| Complete mechatronic | Multiple or mechanical faults | Mid-high |
Diagnosis
Read codes and live data first. Check the battery and wiring, then confirm whether the fault is electronic or hydraulic.
Key takeaways
Replace only the faulty part where possible. On a high-mileage unit with multiple faults, the complete mechatronic is usually better value.
