To Exit Oil Level Sense Mode:
• Press Neutral, Reverse or Drive.
NOTE:
Reading between the Oil Level Sensor and the dipstick may not agree because the
OLS compensates for fluid temperatures.
NOTE:
To correctly check the transmission fluid level using the dipstick, the transmission
fluid must be at operating temperature. The oil level sensor method of checking
the fluid level compensates for transmission fluid temperature between 60º C -
104º C (140º F - 220º F). Any temperature below 60º C (140º F) or above 104º C (220º F)
will result in an error code.
TRANSMISSION LUBRICATING FLUID
Transmission performance, reliability and durability are
dependent on the type of lubricating fluids used. From the fac-
tory, the transmission has been filled with TranSynd
TM
syn-
thetic transmission fluid. TranSynd
TM
synthetic transmission
fluid extends the service intervals. A small tag has been
attached to the dipstick identifying that the transmission is
filled with TranSynd
TM
synthetic transmission fluid. The dip-
stick/oil fill is located between the engine and transmission
underneath the engine access door in the bedroom.
CAUTION:
Do not mix Dexron III® transmission fluid
with TranSynd
TM
Synthetic transmission fluid.
Fluid and Internal Filters Change Interval:
Fluid and internal filters may require changing earlier
depending on the severity of operating conditions. 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.
INFORMATION:
Refer to the Allison transmission owner’s manual or contact an authorized Allison
service center for change intervals.
