Operation, Meritor SureShift
Refer to the Meritor website for additional information, www.meritor.com.
Manual Mode
There is no slide switch on the Meritor SureShift control. Only the manual mode is available.
Driver Message Center
Gear information is presented to the driver via the level III ICU Driver Message Center. The current forward numerical gear is displayed until a new gear is requested. During the shifting process, the letters "SH" appear until the shift is completed. Then, the newly engaged numerical gear is displayed. When neutral (N) is engaged, "N" will appear on the message display screen. When reverse (R) is engaged, "RL" will appear on the message display screen.
Important: The information shown on the message display screen indicates the state of the transmission only, not the state of the SmartShift control.
Neutral Position
Neutral (N) is in the center of the three positions of the selector switch at the end of the control. Select neutral by sliding the mode selector switch to the center position.
Note: Neutral is always available during operation. When in neutral, upshift and downshift requests are ignored. If the mode selector switch is moved from neutral to forward (F) while the vehicle is moving, the transmission will shift into a gear causing the engine to go to a high torque level, under the engine's rated torque.
Selecting a Starting Gear
-
Select forward (F) by sliding the selector switch downward to the next position below the neutral position.
Note: When forward is selected, the transmission controller is signaled to engage the default starting gear.
-
Select a different starting gear by pulling upward on the control while the vehicle is stopped and in Forward, before disengaging the clutch to engage the selected gear.
Note: Each pull upward on the control increases the starting gear by one gear, but no higher than fourth gear. The number of the selected starting gear is displayed for one second and then the signal to disengage the clutch "CL" is displayed. Disengaging the clutch will engage the selected starting gear, which will now be stored in memory as the default starting gear. However, when the transmission controller is reinitialized at the beginning of another power cycle, the starting gear will default to the originally preprogrammed starting gear. The transmission may also be programmed so that it is not possible to select a starting gear other than the preprogrammed default starting gear.
Upshifting
With the transmission in forward (F), request an upshift by pulling upward on the control. If the requested gear is available, the transmission will upshift.
Note: If a requested gear is not available, an audible warning will sound and a message will appear on the message display screen advising that the gear is not available. An unavailable requested upshift is not stored in memory. The upshift must be requested again. All shift requests with the clutch disengaged, while the vehicle is in motion, will be ignored. Skip shifting is not available with the Meritor version of SmartShift.
Downshifting
With the transmission in forward (F), request a downshift by pushing downward on the control. If the requested gear is available, the transmission will downshift.
Note: If a requested gear is not available, an audible warning will sound and a message will appear on the message display screen advising that the gear is not available. An unavailable requested downshift is not stored in memory. The downshift must be requested again. All shift requests with the clutch disengaged, while the vehicle is in motion, will be ignored. Skip shifting is not available with the Meritor version of SmartShift. While in the forward position in the lowest available gear, a downshift request will not cause a shift into neutral.
Reverse
-
To select reverse (R), slide the mode selector switch upward to the next position above the Neutral position.
Note: Reverse low (RL) is the default reverse gear.
-
Select reverse high (RH) by pulling upward on the control before disengaging the clutch.
Note: It is not possible to shift between low range reverse and high range reverse with the vehicle in motion. If reverse is selected above the minimum detectable speed in Forward, an audible warning will sound and a warning message will appear on the message display screen.
Using the Clutch
Use the clutch to start and stop the vehicle.
