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.
Transmission performance, reliability and durability are
important influences in the type of fluids used. The transmission
has been factory tested using TranSynd
TM
synthetic transmission
fluid.
CAUTION: The ISB-300 engine with a
2000MH transmission requires using
TranSynd
TM
synthetic transmission fluid. Use
of any type of transmission lubricating fluid
other than TranSynd
TM
will void the warranty.
The dipstick and an oil fill are located between the engine
and transmission underneath the engine access door in the
bedroom. A small tag has been attached to the dipstick
identifying the use of TranSynd
TM synthetic transmission
fluid. A remote fill has been install in the rear of the
motorhome. The orange colored cap can identify this. The
fluid does not need to be carried through the motorhome.
Fluid and Internal Filters Change Interval Recommendations:
The fluid and internal filters may require changing earlier depending on the
severity of operating conditions. The fluid must also be changed whenever there is
evidence of dirt or high temperature operation as indicated by discoloration, strong
odor or fluid analysis. Local conditions, severity of operation or duty cycle will
dictate more or less frequent service intervals. Contact an authorized Allison
Service center for change intervals.
