AUTOMATIC TRANSAXLE CLEANING
AME571401030A01
Cleaning Notes
1. Clean the transaxle exterior thoroughly with steam, cleaning solvents, or both, before disassembly.
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.
2. Clean the removed parts with cleaning solvent, and dry with compressed air. Clean out all holes and passages
with compressed air, and verify that there are no obstructions.

Precaution
General notes
1. Disassemble the transaxle in a clean area (dust-proof 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. Because 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 transaxle range switch.
3. Set the transaxle to a transmission stand using
the SST.
Caution
•••• Be careful not to scratch the mating
surfaces of the control valve body cover
and the transaxle case.
•••• After removing the control valve body
cover, remove the liquid gasket
remaining on the mating surfaces.
4. Remove the control valve body cover.
5. Disconnect coupling connector between the
solenoid valves and the terminal component.
6. Remove the bolts which secure the control valve
body to the transaxle case as shown in the figure.
Note
• When removing control valve body, be
careful not to drop the manual valve.
7. Remove the control valve body from the transaxle
case.
Caution
•••• If the seal ring has dropped or is
scratched, do not reuse it.
