Non-Trouble Code Procedures

LINK PRESSURE CHECK PROCEDURE
The AISIN 50-40LE Automatic transaxle uses a vane type oil pump to produce hydraulic pressure, and a transaxle pressure control solenoid to control that pressure at the pressure regulator valve, after it leaves the pump. Line pressure are calibrated for 2 sets of gear range Drive and Reverse. This allows the transaxle line pressure to be appropriate for different pressure needs in different gear range.

1. Remove the oil pressure test plug on transaxle case and mount oil pressure gauge (KM-498-B).
2. Check the four wheels.
3. Fully apply the parking brake.
4. Start the engine and allow it to warm up at idle.
5. Step down strongly on the brake pedal with your left foot.
6. Shift into "D" or "R" range to measure line pressure.
7. Apply the accelerator pedal with your right foot, and measure the line pressure at the engine speed (stall speed 2250 ± 200 rpm).

LOCATING FLUID LEAKS
General Method
1. Verify that the material leaking is transaxle fluid.
2. Thoroughly clean the suspected leak area.
3. Allow the transaxle to reach the normal operating temperature of 176-194°F (80-90°C).
4. Park the vehicle over a clean paper or a clean cardboard.
5. Turn the engine OFF and look for fluid spots on the paper.
6. Make the necessary repairs to correct the leak.

Caution: Do not racing more than 5 seconds or the automatic transaxle damaged.

Powder Method
1. Thoroughly clean the suspected leak area.
2. Apply an aerosol type powder, such as foot powder, to the suspected leak area.
3. Allow the transaxle to reach the normal operating temperature of 176 - 194°F (80 - 90°C).
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 to correct the leak.

Once the leak point is found, the source of the leak must be determined and repaired.
