Unusual Noises Reveal Patrol Transmission Trouble

One of the clearest Nissan Patrol signs of transmission trouble1 is the appearance of unusual noises during gear shifts. Sounds like grinding, whining, and clunking often indicate that internal gears and bearings are wearing unevenly or transmission fluid is degraded. Grinding noises can signify misaligned gears or worn metal-on-metal contact, while whining might point to fluid circulation issues. These noises usually worsen over time, especially if the vehicle continues to run without maintenance. Any new or persistent sound coming from your transmission should trigger an inspection by a qualified technician. Ignoring these auditory clues can dramatically shorten the lifespan of your Patrol’s transmission system.
