[Colombia81er]

I want to change my fluids on my 99 Pathy Transfer case and rear axle what does this car recommend as far as fluids. Cause the car sat for well over a year and when the car is cold it locks. Hard to explain so i want to change them. Oil was horrible BLACK n Gunky.... Just did one i will run it for 1500 miles then change it again.

Best SUV i have bought so far

• Transfer fluid: 2.32 quarts
  Use Nissan Matic D or equivalent Dexron III/Mercon, or GL-4 gear oil. ATF is used in the factory. Do not mix ATF and gear oil in the transfer case.
• Rear differential: 2.96 quarts
  Use GL-5 fluid, preferably 80W-90. 75W-90 is usable as well.
