Nissan (Patrol) 4-speed auto / 5-speed auto (Y62) Faults & Repairs Common Problems

The Nissan Patrol’s automatic transmissions, specifically the 4-speed and 5-speed auto (Y62) gearboxes, have been the subject of various owner reports regarding common issues. While these gearboxes are generally reliable, certain problems have been frequently noted by owners.

• Transmission Overheating – Excessive heat can cause transmission fluid to break down, leading to poor lubrication and potential damage to internal components.
• Slipping Gears – Occurs when the transmission unexpectedly changes gears, often due to worn-out clutches or low transmission fluid levels.
• Delayed Gear Engagement – A noticeable delay when shifting from park to drive or reverse, often caused by low fluid levels or worn components.
• Fluid Leaks – Transmission fluid leaks can lead to low fluid levels, causing overheating and gear slippage if not addressed promptly.
• Torque Converter Issues – Problems with the torque converter can cause shuddering, slipping, or overheating, affecting overall transmission performance.
• Erratic Shifting – Unpredictable gear changes can result from faulty sensors, solenoids, or issues with the transmission control module.
• Check Engine Light – A lit check engine light may indicate transmission issues, often requiring diagnostic scanning to identify specific problems.
• Grinding or Shaking – Unusual noises or vibrations during gear shifts can signal worn gears or other internal transmission issues.
• Failure to Shift – The transmission may refuse to shift into certain gears, often due to mechanical failures or electronic control issues.
• Burnt Fluid Odor – A burnt smell from the transmission fluid indicates overheating or contamination, necessitating immediate attention to prevent damage.

Nissan (Patrol) 5-speed manual Faults & Repairs Common Problems

The Nissan Patrol’s 5-speed manual gearbox has been a subject of discussion among owners due to several common issues. While the vehicle is known for its durability and off-road capabilities, the manual transmission has not been without its challenges.

• Worn Mainshaft Ball Race – The large ball race on the mainshaft often wears out, leading to increased noise and potential gearbox failure if not addressed promptly.
• Perished Shifter Boot – A deteriorated top shifter boot allows dirt to enter the gearbox, causing accelerated wear and potential shifting issues.
• Cracked Selector Forks – Selector forks can crack over time, leading to difficulty in gear selection and potential gearbox malfunction.
• Faulty Rail Interlocks – Rail interlocks may fail, causing issues with gear engagement and potentially leading to gear slippage.
• Interlock Ball and Spring Loss – During dismantling, the interlock ball and spring can fall into the gearbox, causing operational issues if not retrieved.
• Worn Synchro Cones – Synchro cones can wear out, leading to grinding noises during gear changes and difficulty in smooth shifting.
• Damaged Energizer Springs – Energizer springs may become damaged, affecting the synchro operation and leading to rough gear transitions.
• Sealer Deterioration – Over time, the sealer used in place of gaskets can deteriorate, leading to leaks and potential contamination of gearbox components.
• Height Variance in Synchro Cones – Synchro cones may exhibit height variance, which can be checked with a feeler gauge to ensure proper function.
• Gear Wear – Although gears generally do not wear much, any significant wear can lead to noise and inefficient power transmission.
