Transaxle Fluid Level Checking Procedure

Tools Required

DW260-070 Plug Remover/Installer

Inspection Procedure

Start the engine and allow the engine to idle for approximately 5 minutes, or, if possible, drive the vehicle for a few kilometers(miles) to warm the transaxle fluid. Check the fluid level when the transaxle is over 30°C(86°F).

Press the brake pedal and move the shift lever through the gear ranges, pausing a few seconds in each range. Return the shift lever to the park position. (Left-Hand Drive Shown, Right-Hand Drive Similar.)

Raise and suitably support the vehicle.
Place a fluid container below the fluid level plug.

Caution : Do not remove the fluid level plug if the transaxle fluid is hot. This may cause injury if the fluid drains from the plug hole.

Remove the fluid level plug using the plug remover/installer DW260-070. Because the transaxle operates correctly over a range of levels, fluid may or may not drain out of the plug hole when the plug is removed.

Check the oil fluid level. If fluid does not drain through the plug hole after adding a total of 4 liters, then the transaxle was either underfilled or the transaxle is leaking fluid. Inspect the transaxle for fluid leaks. Fix any leaks before setting the transaxle fluid level.

Install the fluid level plug using the plug remover/installer DW260-070.

Tighten

Tighten the Plug to 45 N•m (33 lb-ft).

When the fluid level checking procedure is completed, wipe any fluid from the transaxle case with a rag or shop towel. Also, check that the fluid fill cap and the vent tube are properly installed.

Changing the Fluid

Tools Required

Place a fluid container below the fluid drain plug.
Remove the transaxle fluid drain plug using the plug remover/installer DW260-070.

Tighten

Tighten the Plug to 45 N•m (33 lb-ft).

Adding transaxle fluid. Refer to "Transaxle Fluid Level Checking Procedure" in this section.
Connect the negative battery cable.

Fluid Level Set After Service

Add transaxle fluid through the fill cap hole prior to adjusting the fluid level. The amount of fluid to add should be based on the type of service done.

Adjustment Notice

Use ESSO LT 71141 or TOTAL ATF H50235 transaxle fluid only.
Oil pan removed : 4L (4.2 qt)
Torque converter removed : 2L (2.1 qt)
Complete overhaul : 6.9 ± 0.2L (7.3 ± 0.2qt)
Drain plug removed : 4L (4.2 qt)

Check the transaxle fluid level. Refer to "Transaxle Fluid Level Checking Procedure" in this section.
Add additional fluid through the fill cap hole in 0.5 liter (0.5 quart) increments until the fluid comes out through the plug hole.
Allow the fluid to finish draining out through the plug hole, then install the fluid level plug.
When the fluid level setting procedure is completed, wipe any fluid from the transaxle case with a rag or shop towel. Also, check that the fluid fill cap and the vent tube are properly installed.

Repairing Fluid Leaks

Locating Leaks

General Method

Verify that the leak is transaxle fluid.
Thoroughly clean the suspected leak area.
Operate the vehicle for about 25 kilometers (15 miles) or until the transaxle reaches normal operating temperature, 88°C (190°F).
Park the vehicle over clean paper or cardboard.
Turn the engine off and look for fluid spots on the paper.
Make the necessary repairs to correct the leak.

Powder Method

Thoroughly clean the suspected leak area.
Apply an aerosol-type powder (foot powder) to the suspected leak area.
Operate the vehicle for about 25 kilometers (15 miles) or until the transaxle reaches normal operating temperature, 88°C (190°F).
Turn the engine off.
Inspect the suspected leak area and trace the leak path through the powder to find the source of the leak.
Make the necessary repairs.

Repairing the Fluid Leak

The following are potential causes for fluid leaks. Check and repair, as necessary.

Fasteners are not tightened to specifications.
Fastener threads and tapped holes are dirty or corroded.
Gaskets, seals or sleeves are misaligned, damaged, or warped, or scratched.
The manual shaft is nicked or damaged.
There is a loose or worn bearing causing excess seal or sleeve wear.
Case or component porosity.
The fluid level is too high.
There is a plugged vent or a damaged vent tube.
There is water or coolant in the fluid.
Fluid drain back holes are plugged.

Case Porosity Repair

Caution : Epoxy adhesive may cause skin irritations and eye damage. Read and follow all information on the container label as provided by the manufacturer.

Thoroughly clean the area to be repaired with a cleaning solvent. Air dry the area.
Using instructions from the manufacturer, mix a sufficient amount of epoxy to make the repair.
While the transaxle case is still hot, apply the epoxy. You can use a clean, dry soldering acid brush to clean the area and also apply the epoxy cement. Make certain that the area to be repaired is fully covered.
Allow the epoxy cement to dry for 3 hours before starting the engine.
Repeat the fluid leak diagnosis procedures. Refer to "Fluid Leak Diagnosis and Repair" in this section.
