FLUID LEVEL AND CONDITION
The transmission and differential have sepa-
rate oil sumps. The transmission sump requires
automatic transmission fluid. The differential
sump requires petroleum based hypoid gear
lube.
TRANSMISSION SUMP
The transmission sump has a dipstick to check oil
similar to most automatic transmissions. It is located
on the left side of the engine compartment. Be sure to
wipe all dirt from dipstick handle before removing.
The torque converter fills in both the ‘‘P’’ Park and
‘‘N’’ Neutral positions. Place the selector lever in ‘‘P’’
Park to be sure that the fluid level check is accurate.
The engine should be running at idle speed for at
least one minute, with the vehicle on level
ground. The fluid should be at normal operating
temperature (approximately 82 C. or 180 F.). The fluid
level is correct if it is in the ‘‘HOT’’ region (cross-
hatched area) on the oil level indicator (Fig. 1).
Low fluid level can cause a variety of conditions
because it allows the pump to take in air along with the
fluid. As in any hydraulic system, air bubbles make the
fluid spongy, therefore, pressures will be low and build
up slowly.
Improper filling can also raise the fluid level too
high. When the transaxle has too much fluid, the gears
churn up foam and cause the same conditions which
occur with a low fluid level.
In either case, air bubbles can cause over heating
and/or fluid oxidation, and varnishing. This can inter-
fere with normal valve, clutch, and accumulator opera-
tion. Foaming can also result in fluid escaping from the
transaxle vent where it may be mistaken for a leak.
Along with fluid level, it is important to check the
condition of the fluid. When the fluid smells burned,
and is contaminated with metal or friction material
particles, a complete transaxle recondition is needed.
Be sure to examine the fluid on the dipstick closely.
If there is any doubt about its condition, drain out a
sample for a double check.
After the fluid has been checked, seat the dipstick
fully to seal out water and dirt.
The transmission fluid level should be inspected at
least every six months.
DIFFERENTIAL SUMP
The differential sump is checked separately from
the transmission. A fill plug located on the side of
the transaxle must be removed to check fluid level
(Fig. 2). The fluid should be level with the bottom of
the fill hole. The differential capacity is .946 liters
(32 ounces).
Inspect the differential area during engine oil
changes for any leaks. If leakage is present, deter-
mine the source of the leak and repair as required.
Remove the fill plug and verify the proper level. Ad-
just if needed.
SELECTION OF LUBRICANTS
It is important that the proper lubricants be used
in the 42LE transaxle. Mopar ATF Plus (Automatic
Transmission Fluid-Type 7176) should be used in the
transmission side of the transaxle. Substitute fluids
can induce torque converter clutch shudder.
The differential side of the transaxle should be
filled with Mopar petroleum based hypoid gear lubri-
cant 80W-90. Synthetic gear lubricants should not be
used.
SPECIAL ADDITIVES
Chrysler Corporation does not recommend the ad-
dition of any fluids to the transmission, other than
the fluid listed above. An exception to this policy is
the use of special dyes to aid in detecting fluid leaks.
The use of transmission sealers should be avoided,
since they may adversely affect seals.
