Standard Procedure - Differential Sump Drain And Refill - Chrysler 300M Service Manual

21 - 98 TRANSAXLE
FLUID (Continued)
NOTE: The 42LE Transaxle has separate transmis-
sion and differential fluid sumps. Only fluids of the
type labeled Mopar
sion Fluid) should be used in the transaxle sump. A
filter change should be made at the time of the
transmission oil change. The magnet (on the inside
of the oil pan) should also be cleaned with a clean,
dry cloth.
NOTE: If the transaxle is disassembled for any rea-
son, the fluid and filter should be changed.
FLUID/FILTER SERVICE (RECOMMENDED)
(1) Raise vehicle on a hoist (Refer to LUBRICA-
TION & MAINTENANCE/HOISTING - STANDARD
PROCEDURE). Place a drain container with a large
opening, under transaxle oil pan.
(2) Loosen pan bolts and tap the pan at one corner
to break it loose allowing fluid to drain, then remove
the oil pan.
(3) Install a new filter and o-ring on bottom of the
valve body and tighten retaining screws to 5 N·m (40
in. lbs.).
(4) Clean the oil pan and magnet. Reinstall pan
using new Mopar Silicone Adhesive sealant. Tighten
oil pan bolts to 19 N·m (165 in. lbs.).
(5) Pour four quarts of Mopar ATF+4 (Automatic
Transmission Fluid) through the dipstick opening.
(6) Start engine and allow to idle for at least one
minute. Then, with parking and service brakes
applied, move selector lever momentarily to each
position, ending in the park or neutral position.
(7) Check the transaxle fluid level and add an
appropriate amount to bring the transaxle fluid level
to 3mm (1/8 in.) below the lowest mark on the dip-
stick (Fig. 237).
(8) Recheck the fluid level after the transaxle has
reached normal operating temperature (180°F.).
(Refer to 21 - TRANSMISSION/TRANSAXLE/AUTO-
MATIC - 42LE/FLUID - STANDARD PROCEDURE).
(9) To prevent dirt from entering transaxle, make
certain that dipstick is fully seated into the dipstick
opening.
DIPSTICK TUBE FLUID SUCTION METHOD
(1) When performing the fluid suction method,
make sure the transaxle is at full operating temper-
ature.
(2) To perform the dipstick tube fluid suction
method, use a suitable fluid suction device (Vacula™
or equivalent).
(3) Insert the fluid suction line into the dipstick
tube.

NOTE: Verify that the suction line is inserted to the
lowest point of the transaxle oil pan. This will
ensure complete evacuation of the fluid in the pan.
(4) Follow the manufacturers recommended proce-
dure and evacuate the fluid from the transaxle.
(5) Remove the suction line from the dipstick tube.
(6) Pour four quarts of Mopar ATF+4 (Automatic
Transmission Fluid) through the dipstick opening.
(7) Start engine and allow to idle for at least one
minute. Then, with parking and service brakes
applied, move selector lever momentarily to each
position, ending in the park or neutral position.
(8) Check the transaxle fluid level and add an
appropriate amount to bring the transaxle fluid level
to 3mm (1/8 in.) below the lowest mark on the dip-
stick (Fig. 237).
(9) Recheck the fluid level after the transaxle has
reached normal operating temperature (180°F.).
(Refer to 21 - TRANSMISSION/TRANSAXLE/AUTO-
MATIC - 42LE/FLUID - STANDARD PROCEDURE)
(10) To prevent dirt from entering transaxle, make
certain that dipstick is fully seated into the dipstick
opening.
