This is a reliable and hardy machine, but it is often installed with very powerful motors.
With frequent and sharp acceleration, the solenoids become clogged with clutch wear products.
Burnt clutches cause vibrations, and they break the oil pump bearing
Aluminum pistons and drums often don't handle overly aggressive riding.
All automatic transmissions of this line require regular updating of bushings and rubber gaskets
