DYNASTY 2006 CHASSIS INFORMATION — SECTION 10 • 351
CAUTION:
Do not use Economy Mode in heavy stop and go traffic or mountainous terrains. Frequent
shifting while using heavy throttle occurs in Economy Mode and increases transmission fluid
temperature. Exit Economy Mode until road conditions improve.
NOTE:
The Mode button is used by the service technician to access diagnostic codes when
troubleshooting. The diagnostic circuitry must be enabled to display.
• When the Auxiliary Braking device is used, the display changes to a default reading of 2 or 3. The
transmission is not in second or third gear. This is only a reference for the transmission downshift points to
optimize the engine braking effect.
CAUTION:
Engine temperature may rise when ascending long
grades using full throttle. Towing a load will increase the
demand on the engine. If this occurs, manually shift the
transmission to the next lower gear and use less throttle.
The engine will use less fuel and RPM should increase.
NOTE:
The transmission will not accept a manually selected gear change to occur if the gear
selected is out of the specified operating range.
NOTE:
The transmission will not shift into gear from Neutral if the engine RPM is at or above 900.
The display will flash “6” indicating the engine RPM is excessive. Select “N” and lower the
engine RPM.
Check Trans Indicator
The electronic control system of the transmission is programmed to alert operator of a problem with the
transmission system, and reacts automatically to protect the motorhome and transmission from damage. Normally,
the Check Trans indicator on the speedometer LCD will display when there is an error condition. The indicator
will go out after the engine has started. The transmission system should be checked immediately if the Check
Trans indicator displays. The Check Trans warning indicates the ECU has detected a fault and recorded a
diagnostic code. The Check Trans warning is accompanied by a fl ashing display from the shift selector.
The shift selector display will show the actual range attained and the transmission will not respond to shift
selector requests when the ECU detects a Do Not Shift (DNS) condition. Indications from the shift selector
inform the operator that the transmission is operating at reduced capabilities. The transmission generally will
downshift to 4th gear. The torque converter will not “lock-up” and engine speed is automatically reduced.
Direction changes (i.e. forward to reverse) will not be allowed. This allows time to fi nd a safe place to park the
motorhome to prevent transmission damage. If the engine is shut off, then started after a Check Trans indication,
the transmission remains in Neutral until the fault has been corrected. Service should be performed immediately
in order to minimize potential damage to the transmission.
NOTE:
Contact an authorized Allison Transmission service center whenever a transmission
related concern arises. For some problems, fault codes may be registered without the ECU
activating the Check Trans indicator. An authorized Allison Transmission Service center will
have the equipment to check diagnostic codes and correct problems that may arise.
