4. Lower the vehicle with the filler pump still connected
and start the vehicle in P (Park) with the parking brake
and the brake applied. With the engine idling, move
the gear shift control lever through the gear ranges,
pausing a few seconds in each range and adding the
fluid until gear application is felt.
Then add an additional 0.5 litres of fluid. Return the
gear shift lever to P (Park). Turn the engine OFF and
raise the vehicle. Install the fluid filler plug and tighten
it to 33 N•m (24 lb-ft).
5. Drive the vehicle at 3.5 to 4.5 kilometers with light
throttle so that the engine does not exceed 2500
rpm.
This should result in the transmission temperature
being in the range 50 - 60°C (82 - 140°F). With the
brake applied, move the shift lever through the gear
ranges, pausing a few seconds in each range at the
engine idling.
6. Return the gear shift lever to P (Park).
Turn the en-gine OFF and raise the vehicle on the
hoist, if applicable, ensuring the vehicle is level. When
the three minutes passed after the engine stopped,
remove the filler plug.
Check if the fluid level is aligned with the bottom of
the filler hole. If not, add a small quantity of fluid to
the correct level. Install the fluid filler plug and tighten
it to 33 N•m (24 lb-ft).
7. Wipe any fluid around the filler plug with a rag or
shop towel.
FLUID LEAK DIAGNOSIS AND
REPAIR
The cause of most external leaks can generally be lo-cated
and repaired with the transmission in the vehicle.

Methods for Locating Leaks

General method
1. Verify that the leak is transmission fluid.
2. Thoroughly clean the suspected leak area.
3. Drive the vehicle for approximately 25 km (15 miles)
or until the transmission reaches normal operating
temperature (88°C, 190°F).
4. Park the vehicle over clean paper or cardboard.
5. Turn the engine OFF and look for fluid spots on the
paper.
6. Make the necessary repairs to correct the leak.

Powder method
1. Thoroughly clean the suspected leak area.
2. Apply an aerosol type powder (foot powder) to the
suspected leak area.
3. Drive the vehicle for approximately 25 km
(15 miles) or until the transmission reaches normal
operating temperature (88°C, 190°F).
4. Turn the engine OFF.
5. Inspect the suspected leak area and trace the leak
path through the powder to find the source of the
leak.
6. Make the necessary repairs.

Dye and black light method

1. Add dye to the transmission through the transmission
fluid filler plug. Follow the manufacturer's recommen-
dation for the amount of dye to be used.
2. Use the black light to find the fluid leak.
3. Make the necessary repairs.

Repairing the fluid leak

Once the leak point is found the source of the leak must
be determined. The following list describes the potential
causes for the leak:
• Fasteners are not torqued to specification.
• Fastener threads and fastener holes are dirty or
corroded.
• Gaskets, seals or sleeves are misaligned, damaged
or worn.
• Damaged, warped or scratched seal bore or gasket
surface.
• Loose or worn bearing causing excess seal or sleeve
wear.
• Case or component porosity.
• Fluid level is too high.
• Plugged vent or damaged vent tube.
• Water or coolant in fluid.
• Fluid drain back holes plugged.
