Disadvantages of the Honda B7WA gearbox
- This is a fairly robust transmission, but it is installed with powerful V6 power units;
- Therefore, overly active owners wear out the torque converter clutch very quickly;
- Then, wear debris clogs the oil channels and filters, causing jerking and lurching;
- Also, by 150,000 km, severe wear of the shaft sealing rings is common;
- This causes the oil pressure in the automatic transmission to drop and the clutch packs to burn out.
