( 1) - Approximate quantity listed.
( 2) - Use an API energy conserving engine oil that is certified for
gasoline engines.
( 3) - Add this amount of fluid. Start engine and shift transmission
through all gears and back to Neutral. Add additional fluid to
bring fluid level to the MIN mark on dipstick. Recheck fluid
level with transmission at normal operating temperature. Adjust
fluid level to MAX mark on dipstick. Approximate drain and
refill capacity is 4.0 qts. (3.8L).
( 4) - Quantity may vary by type of oil cooler and oil cooler lines.
( 5) - Verify type of transmission used before servicing. The AX 15
uses a flywheel housing bolted to the front of the transmission.
The NV 3500 uses a flywheel housing which is an integral part of
the transmission housing.
( 6) - Models with Trac-Lok limited slip differential must have 5 ozs.
(.15L) of Mopar Trac-Lok Friction Modifier added if lubricant is\
changed.
( 7) - Rear differential may be identified by number of bolts on rear
cover. The 8 1/4" ring gear has 10 bolts on rear cover and 9
1/4" ring gear has 12 bolts on rear cover.
( 8) - Use only Mopar power steering fluid. DO NOT use automatic
transmission fluid.
