Preventive Measures
Help the electronic 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:
1. The shifting feels odd.
2. The transmission leaks fluid.
3. Unusual transmission-related sounds (changes in sound caused by normal engine thermo-
static fan cycling, while climbing a long grade with a heavy load, have been mistaken for
transmission-related sounds).
4. The CHECK TRANS light comes on frequently.
Periodic Inspections
For easier inspection, the transmission should be kept clean. Make periodic checks for loose bolts and
leaking fluid lines. Check the condition of the electrical harnesses regularly. Check the engine cooling
system occasionally for evidence of transmission fluid which would indicate a faulty oil cooler. Report
any abnormal condition to the Allison dealer.
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 supply of fluid. If the fluid level is too high, the fluid can aerate. Aerated fluid
can cause the transmission to shift erratically or overheat.
NOTE:
The motorhome should be stationary for approximately two minutes prior to
checking the fluid levels to ensure fluid is stabilized.
