Filling
NOTICE
Operating a manual transmission with the fluid
level higher or lower than recommended can re-
sult in transmission damage. Do not overfill the
transmission; overfilling will force fluid out of the
case through the main shaft openings. Fluid over-
flow may also drain onto the clutch or clutch
brake, causing additional problems.
1.
Add transmission fluid until it is level with the
lower edge of the fill opening. See
for the
correct level. See
for approved transmis-
sion lubricants and
for lubricant
