GENERAL INFORMATION
The NV3500 is a medium-duty, 5-speed, constant
mesh, fully synchronized manual transmission. Fifth
gear is an overdrive range with a ratio of 0.0729:1.
The NV3500 is used with 3.9L and 5.2L engines and
is available in two and four-wheel drive configura­
tions.
The transmission gear case consists of two alumi­
num housings (Fig. 1). The clutch housing is not a
removable component. It is an integral part of the
transmission front housing.
Roller bearings are used to support the transmis­
sion shafts in the two housings. The transmission
gears all rotate on caged type needle bearings.
The NV3500 has a single shaft shift mechanism.
The three shift forks are all mounted on a one shift
shaft. The shaft is supported in the front and rear
housings by bushings and one bearing. Internal shift
components consist of the forks, shaft, shift lever
socket, and detent components (Fig. 2).

TRANSMISSION LUBRICANT
Required lubricant for the NV3500 is Mopar Man­
ual Transmission Lubricant, P/N 4761526. This is the
only lubricant to be used in NV3500 transmissions.
No other lubricants are acceptable, or recommended.
TRANSMISSION LUBRICANT LEWEL AND
CAPACITY ' •
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 accu­
rate lubricant level check. A drive-on type of hoist is
recommended for this purpose.
Lubricant capacity of the NV3500 is approximately
1.98 liters (4.2 pints). This represents the approxi­
mate quantity needed to refill the transmission after
a lubricant change or overhaul.
