Disadvantages of the Honda BA7A gearbox
- The oil and both filters (coarse and fine) need to be changed every 40,000 km;
- Otherwise, these filters will become clogged with dirt, which will lead to a decrease in oil pressure in the transmission;
- This will lead to jerky shifts and rapid wear of the belt or cones.
