This Genuine Nissan O-ring is a critical seal for the automatic transmission in a Nissan Patrol GU and Navara D23. It is fitted directly onto the transmission's input shaft, where it creates a high-pressure seal with the torque converter hub to prevent any leakage of automatic transmission fluid.
Over time and through countless heat cycles, the original rubber O-ring can become hard, brittle, and lose its sealing ability. A failing seal will cause transmission fluid leaks, which can lead to low fluid levels, poor shifting performance, overheating, and eventually, catastrophic internal transmission damage. Replacing it is a preventative measure against a very expensive failure.
Replacing this O-ring is a major workshop job that requires the removal of the transmission. It is wise to replace other accessible seals, like the engine's rear main seal, at the same time. Fresh automatic transmission fluid is required to complete the job.
