Dodge 2011 Ram Diesel - Manual (Page 128)

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).
CAUTION!
Be aware that if the fluid level is below 50°F (10°C),
it may not register on the dipstick. Do not add fluid
until the temperature is elevated enough to produce
a accurate reading.
8. Check for leaks. Release the parking brake.
NOTE: To prevent dirt and water from entering the
transmission after checking or adding fluid, make sure
