NOTE
Before checking the oil level, the en-
gine must be idling and the transmis-
sion in neutral for at least 2 minutes.
Lubricant temperature must be be-
tween 60 °F and 120 °F (15.5 °C and
48.8 °C).
If the transmission operating angle is more
than 12° (or roughly a 21% grade),
improper lubrication will occur. The
operating angle is the transmission
mounting angle in the chassis plus the
percent of upgrade (expressed in degrees).
Transmission Lubrication Change
Intervals
Lubricant changes should be based on a
combination of the intervals shown in
vehicle operator manual Lubrication
Specification Manual, and user judgment
based on the application and operating
environment. Extending drain intervals
beyond those shown in the tables is not
recommended and will put warranties at
risk.
Inspect the transmission exterior for leaks.
Look around the oil filter and exterior seals
for damage and replace as necessary.
On-Highway
Check fluid levels and inspect for leaks at
regular PM maintenance intervals, not to
exceed 12,000miles. Drain and replace
lubricant every 500,000 miles / 800,000
km.
Off-Highway
Check fluid levels and inspect for leaks
every week. Drain and replace lubricant
interval should not exceed 60,000 mi /
96,000 km / 6 Months.
Vehicle Towing
When towing the vehicle, the output shaft
of the transmission must not be allowed to
spin or turn. If the vehicle is towed with the
drive wheels still in contact with the road
surface, the vehicle axle shafts or driveline
must be removed or disconnected.
CAUTION
Always follow proper manufacturer
towing procedures. Failure to follow
proper towing procedures could result
in damage to the transmission.
How to Drain Fluid
1. Use a drain pan under the
transmission drain plug to collect
oil from the bottom of the
transmission.
