Transmission Lubricating Fluid
Transmission performance, reliability and durability are
important influences in the type of fluids used. The
Transmission has been factory tested using TranSynd
TM
syn-
thetic transmission fluid.
NOTE:
The ISB-300 engine with a 2500MH transmis-
sion requires using TranSyndTM synthetic
transmission fluid.
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.
CAUTION:
Use of any type of transmission lubricating fluid other than TranSyndTM will void
the warranty.
Fluid and Internal Filters Change Interval Recommendations:
The fluid and internal filters may require changing earlier depending on the severity of operating con-
ditions. 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 cen-
ter for change intervals.
Transmission Fluid Level - Cold Check
Cold Check - Manual Check Procedures:
The concept of a cold check is to determine adequate fluid level for safe operating until hot check
can be performed.
To Check the Fluid When Cold:
• Park the motorhome on a level surface. Set the parking brake.
• With the engine operated at a low idle, put the transmission in N (Neutral).
• Chock the wheels to prevent the motorhome from moving.
• Allow the engine to run at idle (500-800 RPM) for one minute.
• Apply the service brakes and shift to D (Drive), then to N (Neutral) and next to R (Reverse) to fill
the system. Finally shift to N (Neutral) and release the service brakes. Allow the engine to continue
to run at idle (500-800 RPM).
