2018 Ram ProMaster City torque

and engine power is reduced to provide enhanced accel-
eration and stability. A feature of the TCS system, Brake
Limited Differential (BLD), functions similar to a limited
slip differential and controls the wheel spin across a driven
axle. If one wheel on a driven axle is spinning faster than
the other, the system will apply the brake of the spinning
wheel. This will allow more engine torque to be applied to
the wheel that is not spinning. This feature remains active
even if TCS and ESC are in the Partial Off mode. Refer to
“Electronic Stability Control (ESC)” in this section for
further information.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver takes their foot off of the
brake pedal. If the driver does not apply the throttle during
this short period of time, the system will release brake
pressure and the vehicle will roll down the hill. The system
will release brake pressure in proportion to the amount of
throttle applied as the vehicle starts to move in the
intended direction of travel.HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•
Vehicle must be stopped.
• Vehicle must be on a 5% (approximate) grade or greater
hill.
• Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle backing
uphill is in REVERSE gear).
HSA will work in REVERSE and all forward gears when
the activation criteria have been met. The system will not
activate if the vehicle is placed in NEUTRAL or PARK.
WARNING!
There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer, when the system will
not activate and slight rolling may occur. This could
cause a collision with another vehicle or object. Always
remember the driver is responsible for braking the
vehicle.
98 SAFETY

CAUTION!(Continued)
Refer to “Recreational Towing” in “Starting And Op-
erating” and “Towing A Disabled Vehicle” in “In Case
Of Emergency” for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the Electronic Range Select
(ERS) shift control (refer to “Electronic Range Select (ERS)
Operation” in this section for further information) to select
a lower gear range. Under these conditions, using a lower
gear range will improve performance and extend transmis-
sion life by reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the transmis-
sion shift schedule, reduce engine torque, and/or expand the
range of torque converter clutch engagement. This is done to
prevent transmission damage due to overheating.
If the transmission becomes extremely hot, the “Transmis-
sion Temperature Warning Light” may illuminate and the
transmission may operate differently until the transmission
cools down.
During cold temperatures, transmission operation may be
modified depending on engine and transmission tempera-
ture as well as vehicle speed. This feature improves warm
up time of the engine and transmission to achieve maxi-
mum efficiency. Engagement of the torque converter
clutch, and shifts into 8th or 9th gear, are inhibited until the
transmission fluid is warm (refer to the “Note” under
“Torque Converter Clutch” in this section). Normal opera-
tion will resume once the transmission temperature has
risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for abnor-
mal conditions. If a condition is detected that could result in
transmission damage, Transmission Limp Home Mode is
activated. In this mode, the transmission may operate only in
166 STARTING AND OPERATING

a fixed gear, or may remain in NEUTRAL. The Malfunction
Indicator Light (MIL) may be illuminated. Limp Home Mode
may allow the vehicle to be driven to an authorized dealer
for service without damaging the transmission.
In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your earliest
possible convenience. Your authorized dealer has diagnos-
tic equipment to assess the condition of your transmission.
If the transmission cannot be reset, authorized dealer
service is required.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly different
feeling or response during normal operation in the upper
gears. When the vehicle speed drops or during some
accelerations, the clutch automatically disengages.
NOTE: The torque converter clutch will not engage until
the transmission fluid is warm [usually after 1 to 3 miles (2
to 5 km) of driving]. Because the engine speed is higher
when the torque converter clutch is not engaged, it may
seem as if the transmission is not shifting properly when
cold. This is normal. The torque converter clutch will
function normally once the transmission is sufficiently
warm.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear. For example, if
you set the transmission gear limit to 5 (fifth gear), the
transmission will not shift above fifth gear, but will shift
through the lower gears normally.

steering fluid to come into contact with hot engine
parts
NOTE: Power steering fluid consumption is very low. If
you need to top off your fluid often and multiple times
have your system inspected by your authorized dealer.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer’s specified transmission fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.
NOTE: No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis-
sion Fluid (ATF) is an engineered product and its perfor-
mance may be impaired by supplemental additives. There-
fore, do not add any fluid additives to the transmission.
Avoid using transmission sealers as they may adversely
affect seals.
