The listed Articulated Trucks have a number of settings for gear limiting that inhibit the machines from changing into higher gears when specific conditions are met and specific pre-selected gears are reached.
Depending on the model of machine and serial number, machines can be inhibited from changing gear if the hoist lever is not in FLOAT and/or if the body is not fully lowered. The default settings at the factory for the gear limits are first gear for all machines.
All of the listed machines have a configurable setting for the gear limit when the hoist lever is not in FLOAT.
The following machines will have a configurable setting for the gear limit when the body is not down:
- 725 (S/N: B1L2218-UP)
- 730 (S/N: B1M2463-UP)
- 735 (S/N: B1N1268-UP)
- 740 (S/N: B1P4703-UP)
- 725C (S/N: LFB1-UP)
- 725C (S/N: TFB1-UP)
- 730C (S/N: LFF1-UP)
- 730C (S/N: TFF1-UP)
- 735B (S/N: L4D1-UP)
- 735B (S/N: T4P1-UP)
- 740B (S/N: L4E1-UP)
- 740B (S/N: T4R1-UP)
- 725C2 (S/N: 2L61-UP; 2T31-UP)
- 730C2 (S/N: 2L71-UP; 2T41-UP)
- 735C (S/N: LFJ1-UP; TFJ1-UP)
- 745C (S/N: LFK1-UP; TFK1-UP)
The following machines can be reworked to have the required hardware to use the configurable setting for the gear limit when the down is not down:
- 725 (S/N: B1L505-2217)
- 730 (S/N: B1M411-2462)
- 735 (S/N: B1N321-1267)
- 740 (S/N: B1P622-4702)
Refer to Special Instruction, REHS5211, "Installation Procedure for the Body Up Indicator" for the rework procedure to install the required hardware.
Note: Some earlier machines might have the configuration available, but the required hardware is not adaptable to the machine. In these cases the "Body Up Sensor Installation Status" is set at the factory to "Not Installed" and the "Body Up Gear Limit" is set to "1" (One).
Information
It is recommended that both gear limits are left at the factory default of first gear for the hoist lever not in FLOAT and the body not fully down. Moving the machine with the hoist lever not in FLOAT may result in damage to the hoist cylinders. Moving the machine with the body not fully lowered may result in damage to the hoist cylinders and body pivots. Moving the machine with the body not fully down may cause issues with overhead clearance and may adversely affect the stability of the machine.
In some circumstances the body of the machine might be removed, so that limitations for the hoist lever not in FLOAT or the body is not fully down is not required. In that case, the settings must be reconfigured to suit the need of the machine.

In order to change the gear limits, use ET to access the Machine Configuration settings in the Transmission ECM.
The following parameters can be configured with the following effects:
Transmission Maximum Forward Gear
This effect inhibits the machine from using any gear higher than the setting. The factory setting is the highest gear available to the machine.
Body Float Gear Limit
This effect inhibits the machine from using any gear higher than the setting when the position of the Hoist Lever is not in FLOAT and the status of "Hoist System Enable Status" is "Enabled". The factory setting is "1". "2" for 735C and 745C machines. The range for this setting is "0", "1", "2", and "3". Set to "0" if you want the machine to be able to shift to any gear. "1" if you want the machine to be only able to use first gear. "2" if you want the machine to be able to use only first and second gear. "3" if you want the machine to be able to use only first to third gear.
Body Up Sensor Installation Status
When this effect is set to "Installed", the warning lamp on the dash will be illuminated when the body is not fully down. The machine will be inhibited from upshifts according to the setting of "Body Up Gear Limit". If this effect is set to "Not Installed", the warning lamp will not illuminate if the body is not fully down. The machine will not be inhibited from upshifts according to the setting of "Body Up Gear Limit".
Body Up Gear Limit
This effect inhibits the machine from using any gear higher than the setting when the body is not fully down and the status of "Body Up Sensor Installation Status" is "Installed". The factory setting is "1". "2" for 735C and 745C machines. The range for this setting is "0", "1", "2", and "3". Set to "0" if you want the machine to be able to shift to any gear. "1" if you want the machine to be only able to use first gear. "2" if you want the machine to be able to use only first and second gear. "3" if you want the machine to be able to use only first to third gear.
Hoist System Enable Status
When this effect is set to "Enabled", the warning lamp on the dash will be illuminated when the position of the Hoist Lever is not FLOAT. The Hoist Lever will be able to send inputs to the Transmission ECM. If this effect is set to "Disabled", the Hoist Lever will not be able to send inputs to the Transmission. The position of the Hoist Lever will not cause the warning lamp on the dash to illuminate.
