Required tools:
• Small container (to catch fluid)
•
Transmission fluid (See
Transmission Lube Specification on
page 62)
• Standard wrench
• Torque wrench
• 6mm hex bit socket
• 8mm hex bit socket
• Fluid lubricant pump with hose
(optional)
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.
1. Park vehicle on a level surface with
the transmission in neutral, engage
the parking brake, and chock the
tires.
