Caution

• The oil seal is easily damaged by the sharp edges of the torque converter splines. Do not let the

splines contact the oil seal.

• Do not drop the torque converter.

• Do not pinch fingers.

2. Remove the torque converter, and immediately

turn it so that the hole faces upward. This will help
to keep any remaining fluid from spilling.

3. Drain any ATF remaining in the torque converter.
4. Using a flathead screwdriver, position the drive

gear on the oil pump component in the center.

5. Install the torque converter to the transaxle.

Note

• If the automatic transaxle is replaced, flush and inspect the oil cooler.

• When replacing the automatic transaxle, inspect the oil cooler together with flushing it using the following

procedure, and with the oil cooler hose removed.

1. Disconnect the oil cooler hose.
2. Set a clean oil pan up to the oil cooler hose inlet.
3. Blow 491—882 kPa {5—9 kgf/cm

2

, 72—127 psi}

of compressed air from the oil cooler hose outlet
to drain remaining oil.

4. Add new ATF from the oil cooler hose outlet and

blow 491—882 kPa {5—9 kgf/cm

2

, 72—127 psi}

of compressed air to flush. (Repeat 2 or 3 times)

5. Verify that none of the following foreign material is

mixed in with the drained ATF:

• Large metal fragments of φ 0.5 mm {0.02 mm}

or more that cannot pass through the oil
strainer

• Fibrous clutch facing

6. Repeat the procedures from Step 1 to 2 and flush

the inside of the oil cooler.

7. If foreign material such as metal fragments or

clutch facing remains even after the oil cooler is
flushed repeatedly, replace the oil cooler
(radiator).
