A practical replacement scenario can include harsh shifts, clutch drag or loss of drive in a specific range. These symptoms do not prove that one part is the only cause, so the surrounding transmission circuit or assembly should be checked before ordering.
The ZF 0734.401.040 PISTON RING helps transmit or react torque inside a hydraulically applied clutch assembly. In fleet maintenance, transmission rebuilding and field repair, this makes hydraulic apply pressure an important point when the component is inspected or replaced.
During service, replace contaminated oil and identify the cause of overheating before returning the unit to service. This helps protect the replacement part and reduces the chance that an unresolved root cause will create another failure after installation.
