The Allison WT Series requires minimum maintenance. Careful attention to

the fluid level and the connections for the electronic and hydraulic circuits is
very important.

For easier inspection the transmission should be kept clean. Make periodic

checks for loose bolts and leaking fluid lines. Check the condition of the electri-
cal harnesses regularly. Check the engine cooling system occasionally for evi-
dence of transmission fluid which would indicate a faulty oil cooler. Report any
abnormal condition to your allison dealer.

Prevent Major Problems

Help the WTEC III control system oversee the operation of the transmission.

Minor problems can be kept from becoming major problems if you notify an
Allison Transmission distributor or dealer when one of these conditions occur:

The shifting feels odd.

. The transmission leaks fluid.

There are 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).

The CHECK TRANS light comes on frequently.

The Importance of Proper Fluid Levels

Because the transmission fluid cools, lubricates and transmits hydraulic

power, it is important that the proper fluid level be maintained at all times. If the
fluid level is too low, the converter and clutches do not receive an adequate sup-
ply of fluid. If the fluid level is too high, the fluid can aerate. Aerated fluid can
cause the transmission to shift erratically or overheat.

The WT Series oil level sensor (OLS) allows the operator to obtain an indica-

tion of sensor fluid level from the keypad shift selector. Frequently check for the
presence of oil level diagnostics in the transmission. If the OLS has not been
detected, troubleshooting of the OLS circuit is required. This will have to be per-
formed by an Allison Service Center. After the OLS circuit is repaired, ensure
that reset of the “autodetect” or manual selection of the OLS function, using the
Pro-Link, has been accomplished.

Fluid Level Check with the Keypad

• Park the motorhome on a level surface, place the transmission in “N” and set

parking brake.

• The transmission should be at normal operating temperature.
• The motorhome should be stationary for approximately two minutes to

ensure fluid is settle.

• Simultaneously press the arrow up and arrow down buttons one time.
• The delayed fluid level check will display in the digital display window. The

display will be one character at a time. The “o,L” represents oil level check
mode. This will be followed with fluid level indication readings. The “o,K”
