PERIODIC INSPECTIONS
Allison Motorhome Series transmissions require minimum maintenance. Careful
attention to the
fl
uid level and the connections for the electronic and hydraulic
circuits is most important.
For easier inspection, the transmission should be kept clean. Make regular periodic
inspections and check:
•
For loose bolts.
•
For leaking
fl
uid around
fi
ttings, lines, and transmission openings.
•
The condition of the electrical harnesses.
•
The engine cooling system for presence of transmission
fl
uid and check the
transmission
fl
uid for presence of coolant, which would indicate a faulty oil
cooler.
•
The breather (refer to Figure 1 through Figure 4) to make sure it is clean
and free from dirt or debris.
Report any abnormal condition to your nearest Allison distributor or dealer.
PREVENT MAJOR PROBLEMS
Help Allison 4
th
Generation Controls or WTEC III Controls oversee the operation
of the transmission. Minor problems can be kept from becoming major problems
if an Allison Transmission distributor or dealer is noti
fi
ed when one of these
conditions occur:
•
Shifting feels odd.
•
Transmission leaks
fl
uid.
•
Unusual transmission-related sounds (changes in sound caused by normal
engine thermostatic fan cycling, while climbing a long grade with a heavy
load, have been mistaken for transmission-related sounds).
•
CHECK TRANS
light comes on frequently.
