Perform this procedure with the
transmission installed in the vehicle.
CAUTION
DO NOT operate the transmission at
an operating
angle greater than 12°
(approximately 21% road grade). The
operating angle is the transmission
mounting angle plus the road grade
expressed as an angle. Failure to
comply will result in improper transmis-
sion lubrication and may result in
equipment or property damage.

5. Observe the check plug hole:
a. If a small amount of fluid runs

there is sufficient transmission
fluid.
b. IF NO fluid runs out of the
check plug hole, STOP.
Replace check plug and add
fluid to the transmission (see
Adding Transmission Fluid on
page 55).
6. Inspect the check plug and O-ring
for damage. If damaged, replace
with new plug and O-ring.
7. Insert the check plug with O-ring,
and torque plug to 37-43 N·m
(27.3-31.7 lb-ft).
NOTE
Do not over-torque the check plug or
transmission damage may occur.
