If equipped with a PTO or transmission
cooler, start engine and run for 1 to 2
minutes to fill these components with
transmission fluid. Afterwards, turn of
f the
engine and recheck fluid level (see
Checking Transmission Fluid Level on
page 54).
Mixing of Oil Types
CAUTION
Do not mix engine and gear oil in the
same transmission.
Mixing engine and
gear oils could cause damage to the
transmission.
CAUTION
DO NOT use additives or friction modi-
fiers. Neither
are approved for this
transmission. Using an additive or fric-
tion modifier can break down both lu-
brication and transmission compo-
nents, resulting in degraded perform-
ance and equipment damage, and
may affect warranty coverage.
Engine oils and gear oils may not be
compatible; mixing can cause breakdown
of the lubricant and affect component
performance. When switching between
types of lubricants, all areas of each
af
fected component must be thoroughly
flushed.
NOTE
For a list of approved lubricants, see
Transmission Lube Specification
on
page 62.
Troubleshooting
Diagnostics
In the event there is a problem with this
transmission, there are three primary tasks
the driver should perform:
1.
Note the driving condition under
which the problem occurred.
2.
Note the condition of the
transmission under which the
problem occurred (such as
operation mode (Drive, Manual,
Low), current gear, and engine
speed).
3.
Reset system.
T
ransmission Reset Procedure
In some cases, proper transmission
operation can be restored by “resetting” the
Transmission Control Module (TCM). Use
the following procedure to reset the TCM.
1. Continue to drive the vehicle to a
safe location before selecting
neutral (N).
NOTE
Once neutral (N) is selected, a gear en-
gagement may not be allowed depend-
ing on the specific problem.
2. Place the transmission in neutral
(N).
3. Set the vehicle parking brake.
