Operation
MANUAL / Hold Mode Gear
Hold Mode Gear is used to limit the use of MANUAL mode. When Hold Mode
Gear is configured in the Transmission Control Module (TCM) to a specific gear,
MANUAL mode becomes a hold gear function only. The default configuration
for this function in the TCM is Disabled. The configuration can be changed
using ServiceRanger.
• When MANUAL mode is selected and the transmission is in a gear
equal to or greater than the configured Hold Mode Gear, the transmis-
sion will remain in the current gear; any Upshift or Downshift requests
using the transmission driver interface device are not allowed and an
audible tone may be emitted every 10 seconds.
• When MANUAL mode is selected and the transmission is in a gear less
than the configured Hold Mode Gear, the transmission system allows
normal MANUAL mode operation.
Note: The transmission system may automatically override or prevent the
driver’s Upshift or Downshift request on the transmission driver interface
device or automatically initiate a gear change based on vehicle operating condi-
tions. Refer to
“Transmission MANUAL / LOW Mode Override” on page 14.
