WARNING
When operating the vehicle in the transmission limp home
mode, the operator must not rely on the parking brake to hold
the vehicle in place. The service brakes must also be applied.
Failure to comply may result in injury or death to personnel.
NOTE
The operator should consider the following guidelines carefully
with regard to type of mission, environment, terrain, etc., when
deciding on whether to continue the mission, deadline, or return
vehicle to field level maintenance.
(2)
No additional damage to the transmission will occur. The operator can
continue to operate vehicle in the limp home mode and complete mission.
However, the operator must be aware of the following guidelines:
(a)
DO NOT shut off engine until the decision is made to deadline
vehicle. Once the engine is shut off, the vehicle will not be operable
until the problem is corrected.
(b)
As the engine cannot be turned off and the transmission is locked
into gear, the operator will not be able to leave the cab until vehicle
is deadlined.
(c)
The vehicle will not be able to operate in R (reverse).
(d)
Depending on gear range the transmission is locked into, the
operator may not be able to drive vehicle up steep grades.

terrain the vehicle is operating in, the engine and/or transmission
may overheat. The operator must closely monitor the engine coolant
temperature gauge (4) and the transmission oil temperature gauge
(5).
