CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturer’s recommended fluid will result in
more frequent fluid and filter changes. Refer to
“Fluids, Lubricants, and Genuine Parts” in this sec-
tion for the correct fluid type.
Fluid Level Check — 42RLE
Check the fluid level while the transmission is at normal
operating temperature 180° F (82° C). This occurs after at
least 15 miles (25 km) of driving. At normal operating
temperature, the fluid cannot be held comfortably be-
tween the fingertips.
If the transmission overheats, a “HOTOIL” message will
be displayed in the odometer and a chime will sound.To properly check the automatic transmission fluid level,
the following procedure must be used:
1. Operate the engine at idle speed and normal operating
temperature.
2. The vehicle must be on level ground.
3. Fully apply the parking brake.
4. Place the shift lever momentarily into each gear posi-
tion ending with the shift lever in PARK.
5. Remove the dipstick, wipe it clean and reinsert it until
seated.
6. Remove the dipstick again and note the fluid level on
both sides. The fluid level should be between the HOT
(upper) reference holes on the dipstick at normal operat-
ing temperature. Verify that a solid coating of oil is seen
on both sides of the dipstick. If the fluid is low, add as
required into the dipstick tube.
Do not overfill.After

Selection of Lubricant
Use only manufacturer’s recommended fluid. Refer to
“Fluids, Lubricants, and Genuine Parts” in this section
for the correct fluid type.
Maintenance After Off-Road Driving
After extended operation in mud, sand or water, or
similar dirty conditions, have your brake drums, brake
linings, and axle joints inspected and cleaned as soon as
possible. This will prevent any abrasive material from
causing excessive wear or unpredictable braking action.
Following off-road usage, completely inspect the under-
body of your vehicle. Check the tires, body structure,
steering, suspension and exhaust system for damage.
Check the threaded fasteners for looseness, particularly
on the chassis, drivetrain components, steering and sus-
pension. Retighten, if required, to torque values specified
in the Service Manual. Also check for accumulations of
vegetation or brush that could become a fire hazard, orconceal damage to fuel lines, brake hoses, axle pinion
seals, and propeller shafts. Check the air conditioning
drain tube on the lower dash wall in the engine compart-
ment for mud or debris, and clean as required. A plugged
tube will adversely affect air conditioning performance.
