Economy Mode:
Economy mode affects the upshift schedule D-3, D-4, D-5 and downshift schedule D-5, D-4, D-3.
During highway driving, with the cruise control set between 55 and 65 miles per hour, setting the trans-
mission to Economy Mode will eliminate about 99% of transmission downshifts from fifth to fourth when
incurring a slight incline or overpass.
In city driving, with the transmission set to Economy Mode, the transmission will upshift approxi-
mately 200 RPM sooner using less fuel with reduced engine noise. Do not use Economy Mode while
traveling in mountain terrain. The lower RPM shift schedule will reduce the flow of antifreeze, lubricat-
ing oil and airflow through the radiator resulting in increased transmission and engine temperature.
CAUTION:
Do not use the economy mode in heavy stop and go traffic or mountainous terrains.
Frequent shifting occurs when in Economy Mode while using heavy throttle, increasing
transmission fluid temperature. Exit Economy Mode until road conditions improve.
NOTE:
When the Auxiliary Braking device is used, the display will change to a default read-
ing of D-3. This setting is pre-selected at the factory and can only be altered by an
authorized Allison Service center. The transmission is not actually in third gear.
This is only a reference point so the transmission will optimize engine-braking effi-
ciency.
Service:
If the Service display is illuminated a fault may exist with the Shift-By-Wire system. A qualified
service technician should inspect the system.
Flashing Display:
In the event the Display area begins to flash, the transmission has inhibited shift operations. This is an
indicator that range shifts requested might not occur. Certain operating conditions when detected by the
TCM will inhibit shifting to protect from damaging operations. This is in response to diagnostic trouble
codes received by the transmission control system.
Shift inhibits falls within certain categories. Above-idle neutral range shifts are shifts from
N
(Neutral) to
R
(Reverse) or
N
(Neutral) to a forward range when the idle is in excess of 900 rpm (Above-
idle). Forward/Reverse directional shifts are not permitted when measurable output shaft speed is detect-
ed.
NOTE:
Sudden movements or lurching the motorhome with an open throttle can result in
damage to transmission. Avoid this condition by making shifts only when the throt-
tle is closed and engine is at normal idle.
Certain unusual transmission operating conditions detected by the TCM will temporarily limit trans-
mission operations. These conditions are transmission problems. The TCM will lock the Transmission
in a safe gear range to permit the motorhome to be driven to a service location. The TCM may not
respond to additional shift requests. Upshift and downshift may not occur and directional changes will
not occur. Consult the Allison Operator's manual for more information.
