DESCRIPTION
Required lubricant for the NV3550 is Mopart Manual Transmission Lubricant, P/N 4761526. This is the only lubricant to be used in NV3550 transmissions.
No other lubricants are acceptable, or recommended.
The correct transmission lubricant level is to the bottom edge of the fill plug hole (Fig. 3).
The transmission must be level to obtain an accurate lubricant level check. A drive-on type of hoist is recommended for this purpose.
Lubricant capacity of the NV3500 is approximately 2.28 liters (4.8 pints). This represents the approximate quantity needed to refill the transmission after a lubricant change or overhaul.
DRAIN AND FILL PLUG LOCATIONS
The NV3550 fill plug is located in the front housing.
The drain plug is at the bottom rear of the housing (Fig. 3).
