Fluid - Transfer Case: Description and Operation
NV 231 HD and 241 LD Transfer Case
Recommended lubricant for the NV231HD and NV241LD transfer case models is MOPAR Dexron II, or ATF Plus. Use this fluid for topping off
the level, refilling after service, or normal fluid changes.
Do not use anti-friction additives or similar products in the NV23 1HD or NV241LD transfer cases. Use recommended lubricant only.
Approximate lubricant refill capacities are 1.5 to 2 liters (3 to 3.6 pints) for the NV231HD and 2.7 L (5.0 pts.) for the NV241LD.
Correct fluid level for the transfer cases is to the bottom edge of the fill plug hole. Be sure that the vehicle is level when checking the fill level.
