plug(s).
4. Remove the fill plug from the side of the gear
case. Remove the drain plug(s) from the bottom
of the gear case.
5. Clean the magnetic plug(s) before installation.
Use a piece of key stock, or any other conve-
nient steel slug, to short the two magnetic poles
and divert the magnetic field.
6. Install and tighten the drain plug(s) 50 lbf·ft (68
N·m).
Filling
1. Add fluid until it is level with the lower edge of
the fill opening. See Fig. 1. If the transmission
has two fill openings, add fluid to the level of
both fill openings.
See Table 1 for approved transmission lubri-
cants, and Table 2 for lubricant capacities.

CAUTION
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.
IMPORTANT: Do not mix types of fluid, because
of possible incompatibility. Do not use multivis-
cosity fluids or EP (Extreme Pressure) gear flu-
ids. Do not use fluid additives or friction modifi-
ers. If switching from a petroleum based
lubricant to a synthetic, all areas of each af-
