AUTOMATIC TRANSAXLE DISASSEMBLY

id051700502100

Precaution

General notes

•  The oil pan could contain small chips, shavings, and other particles which may be helpful in inspecting the condition of the transaxle and diagnosing certain problems.

To ensure that all foreign particles stay in the oil pan, make sure that the transaxle is never tipped completely over while the oil pan is still installed.

1.  Disassemble the transaxle in a clean area (dustproof work space) to prevent entry of dust into the mechanisms.

2.  Inspect the individual transaxle components in accordance with the QUICK DIAGNOSIS CHART during disassembly.

3.  Use only plastic hammers when applying force to separate the light alloy case joints.

4.  Never use rags during disassembly; they may leave particles that can clog fluid passage.

5.  Several parts resemble one another; arrange them so that they do not get mixed up.

6.  Disassemble the control valve component and thoroughly clean it when the clutch or brake band has burned or when the ATF has degenerated.

Warning

•  Although the stand has a self-locking brake system, there is a possibility that the brake may not hold when the transaxle is held in a lopsided position on the stand. This would cause the transaxle to turn suddenly, causing serious injury. Never keep the transaxle tilted to one side. Always hold the rotating handle firmly when turning the transaxle.

Disassembly procedure

1.  Remove the torque converter, and immediately turn it so that the hole faces upward.

This will help to keep any remaining fluid from spilling.

2.  Remove the ATF dipstick and oil filler tube.

3.  Remove the O-ring from the oil filler tube.

4.  Remove the breather hose.

5.  Assemble the SST.

7.  Remove the input/turbine speed sensor.

8.  Remove the O-ring from the input/turbine speed sensor.

9.  Remove the oil pressure switch. (with oil pressure switch)

10.  Remove the transaxle range switch.

11.  Remove the vehicle speed sensor.

12.  Remove the O-ring from the vehicle speedometer sensor.

13.  Remove the connector pipe, connector bolt and oil pipe.

Warning

•  Using compressed air can cause dirt and other particles to fly, out, causing injury to the eyes. Wear protective eye wear whenever using compressed air.

Caution

•  Clean the transaxle exterior thoroughly with a steam cleaner or cleaning solvents before removal.

•  If any old sealant gets into the transaxle during installation of the oil pan, trouble may occur in the transaxle. Remove any old sealant from the transaxle case and oil pan, and clean with cleaning fluids.

14.  Remove the oil pan.

Examine any material found in the pan or on the magnet to determine the condition of the transaxle. If large amounts of material are found, replace the torque converter and carefully inspect the transaxle for the cause.

(1)  Clutch facing material

•  Drive plate and brake band wear

(2)  Steel (magnetic)

•  Bearing, gear, and driven plate wear

(3)  Aluminum (nonmagnetic)

•  Aluminum part wear

15.  Disconnect the solenoid valve connector, ground, and transaxle fluid temperature sensor.
