2021 RAM PROMASTER CITY transmission

210IN CASE OF EMERGENCY
NOTE:
Push the ESC OFF switch, to place the Electronic
Stability Control (ESC) system in Partial Off
mode, before rocking the vehicle Ú page 146.
Once the vehicle has been freed, push the ESC
OFF switch again to restore ESC On mode.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle
and tires. A tire could explode and injure
someone. Do not spin your vehicle's wheels
faster than 30 mph (48 km/h) or for longer than 30 seconds continuously without
stopping when you are stuck and do not let
anyone near a spinning wheel, no matter
what the speed.
CAUTION!
Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after
every five rocking-motion cycles. This will
minimize overheating and reduce the risk of
transmission failure during prolonged efforts
to free a stuck vehicle.
CAUTION!
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drivetrain damage may result.
Revving the engine or spinning the wheels
too fast may lead to transmission over -
heating and failure. It can also damage the
tires. Do not spin the wheels above 30 mph
(48 km/h) while in gear (no transmission
shifting occurring).

IN CASE OF EMERGENCY211
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service.
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow
bars and other equipment designed for this
purpose, following equipment manufacturer’s
instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main
structural members of the vehicle, not to
fascia/bumpers or associated brackets. State
and local laws regarding vehicles under tow
must be observed. If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN mode.
If the ignition key is unavailable, or the vehicle's
battery is discharged, for instructions on
shifting the transmission out of PARK (P) for
towing Ú
page 209.

CAUTION!
Do not use sling type equipment when
towing. Vehicle damage may occur.
When securing the vehicle to a flat bed
truck, do not attach to front or rear suspen-
sion components. Damage to your vehicle
may result from improper towing.

212IN CASE OF EMERGENCY
FCA US LLC recommends towing your vehicle
with all four wheels OFF the ground using a
flatbed.
NOTE:
If flatbed equipment is not available, this
vehicle must be towed with the front wheels
OFF the ground (using a towing dolly, or wheel
lift equipment with the front wheels raised).ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced
Accident Response System.
This feature is a communication network that
takes effect in the event of an impact. Detailed
information can be found on Ú page 168.
EVENT DATA RECORDER (EDR)
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an EDR is
to record data that will assist in understanding
how a vehicle’s systems performed under
certain crash or near crash-like situations, such
as an air bag deployment or hitting a road
obstacle. Detailed information can be found on
Úpage 169.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe transmission
damage. Damage from improper towing is not
covered under the New Vehicle Limited
Warranty.

SERVICING AND MAINTENANCE231
(Continued)
Brake Master Cylinder
The fluid in the master cylinder should be
checked when performing under hood services
or immediately if the “Brake Warning Light” is
illuminated.
Be sure to clean the top of the master cylinder
area before removing the cap. If necessary, add
fluid to bring the fluid level up to the
requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. Brake
fluid level should be checked when pads are
replaced. However, low fluid level may be
caused by a leak and a checkup may be
needed. Use only FCA recommended brake fluid
Ú page 261.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission
fluid to ensure optimum transmission
performance and life. Use only FCA specified
transmission fluid Ú page 261. It is important
to maintain the transmission fluid at the correct
level using the recommended fluid.
NOTE:
No chemical flushes should be used in any
transmission; only the approved lubricant
should be used.
WARNING!
Use only FCA recommended brake fluid
Ú page 261. Using the wrong type of brake
fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory
installed hydraulic master cylinder reser -
voir.
To avoid contamination from foreign matter
or moisture, use only new brake fluid or
fluid that has been in a tightly closed
container. Keep the master cylinder reser -
voir cap secured at all times. Brake fluid in
an open container absorbs moisture from
the air resulting in a lower boiling point. This
may cause it to boil unexpectedly during
hard or prolonged braking, resulting in
sudden brake failure. This could result in a
collision.
Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces; care should be taken to
avoid its contact with these surfaces.
Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
WARNING! (Continued)
CAUTION!
Using a transmission fluid other than FCA
recommended fluid may cause deterioration
in transmission shift quality and/or torque
converter shudder Ú page 261.

232SERVICING AND MAINTENANCE
Special Additives
It is strongly recommended against using any
special additives in the transmission. Automatic
Transmission Fluid (ATF) is an engineered
product and its performance may be impaired
by supplemental additives. Therefore, do not
add any fluid additives to the transmission.
Avoid using transmission sealers as they may
adversely affect seals.
Fluid Level Check
The fluid level is preset at the factory and does
not require adjustment under normal operating
conditions. Routine fluid level checks are not
required; therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service
tools. If you notice fluid leakage or transmission
malfunction, visit an authorized dealer immediately to have the transmission fluid level
checked. Operating the vehicle with an
improper fluid level can cause severe
transmission damage.
Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not
required. However, change the fluid and filter if
the fluid becomes contaminated (with water,
etc.), or if the transmission is disassembled for
any reason.
Upfitter Connectors — If Equipped
The preparation connectors are to be only used
by upfitters. This connector is located under the
dash.

CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage
your transmission components. Such damage
is not covered by the New Vehicle Limited
Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.

TECHNICAL SPECIFICATIONS261
CHASSIS FLUIDS AND LUBRICANTS
Component Fluid, Lubricant, or Genuine Part
Automatic Transmission Use only Mopar ZF 8&9 Speed ATF Automatic Transmission Fluid, or
equivalent.
Failure to use the correct fluid may affect the function or performance of
your transmission.
Brake Master Cylinder We recommend you use Mopar DOT 4.
The fluid must be changed every 24 months. This interval is time based
only, mileage intervals do not apply.
Power Steering Reservoir Use Pentosin CHF 11S power steering fluid meeting FCA Material
Standard MS-11655.
