parked overnight. When checking oil after operating the
engine, first ensure the engine is at full operating tem-
perature, then wait for 30 minutes after engine shutdown
to check the oil.Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Add oil
only when the level on the dipstick is below the “ADD”
mark. The total capacity from the low mark to the high
mark is 2 qts (1.9L).
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
Never operate the engine with oil level below the “ADD”
mark or above the upper “SAFE” mark.

Fluid Level Check – 68RFE (Ram Truck Only)
If your vehicle is equipped with a dipstick, use the
following procedure. If your vehicle has a capped dip-
stick tube, it is sealed and should not be tampered with.
Your authorized dealer has the proper tools to ensure that
the fluid level is set properly. The fluid level should be
checked when the engine is fully warmed up and the
fluid in the transmission is at normal operating tempera-
ture. Operation of the transmission with an improper
fluid level will greatly reduce the life of the transmission
and of the fluid. Check the fluid level whenever the
vehicle is serviced.
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 and press the brake
pedal.
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 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
adding any quantity of oil through the oil fill tube, wait
a minimum of two minutes for the oil to fully drain into
the transmission before rechecking the fluid level.

3. Fully apply the parking brake and press the brake
pedal.
4. Place the shift lever momentarily into each gear posi-
tion ending with the shift lever in PARK. Make sure the
engine is running at idle speed.
5. Remove the dipstick and determine if the fluid is hot
or cold. Hot fluid is approximately 160°F to 175°F (70°C
to 82°C). This is the normal operating temperature after
the vehicle has been driven at least 15 miles (25 km). The
fluid cannot be comfortably held between the fingertips.
Only use the cold region of the dipstick as a rough
reference when doing initial oil level set after transmis-
sion rebuild or transmission refill.
6. Wipe the dipstick clean and reinsert it until seated.
7. 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
MOPAR
AS68RC Automatic Transmission Fluid or
equivalent as required into the dipstick tube. Do not
overfill. Never use any ATF other than MOPAR
AS68RC Automatic Transmission Fluid or equivalent.
After adding any quantity of oil through the dipstick
tube, wait a minimum of two minutes for the oil to fully
drain into the transmission before rechecking the fluid
level.
NOTE: If it is necessary to check the transmission below
the operating temperature, the fluid level should be
between the two COLD (lower) holes on the dipstick
with the fluid at approximately 70°F to 85°F (20°C to
30°C). If the fluid level is correctly established at room
temperature, it should be between the HOT (upper)
reference holes when the transmission reaches 160°F to
175°F (70°C to 82°C).
