11. Blow air into the oil hole as shown in the figure and remove
servo release accumulator piston from transaxle case.
CAUTION:

Strong flow of air will push the accumulator piston out
along with a splash of oil. Cover the area with paper tow-
els and blow air little by little to avoid this.

Wrap the removed accumulator piston in a paper towel.
12. Remove O-ring from servo release accumulator piston.
13. Blow air into the oil hole shown in the figure and remove N-D
accumulator piston and return spring from transaxle case.
CAUTION:

Strong flow of air will push the accumulator piston out
along with a splash of oil. Cover the area with paper tow-
els and blow air little by little to avoid this.

Wrap the removed accumulator piston in a paper towel.
14. Remove O-ring from N-D accumulator piston.
15. Remove lip seals from oil groove for band servo.
INSTALLATION

Note the following, and install in the reverse order of removal.

Set manual shaft in Neutral position, then align manual
plate with groove in manual valve.

After installing control valve assembly to transaxle case,
make sure that selector lever can be moved to all positions.

After completing installation, check for leakage, and fluid
level. Refer to AT- 1 6 , "
Checking A/T Fluid".
CAUTION:

Do not reuse O-ring and lip seal.

Do not reuse oil pan gasket and oil pan fixing bolt.

PRECAUTIONS

Service NoticeEDS001V7

After overhaul refill the transfer with new transfer oil.

Check the oil level or replace the oil only with the vehicle parked on level ground.

During removal or installation, keep inside of transfer clear of dust or dirt.

Replace all tires at the same time. Always use tires of the proper size and the same brand and pattern.
Fitting improper size and unusual wear tires applies excessive force to vehicle mechanism and can cause
longitudinal vibration.

Disassembly should be done in a clean work area.

Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign matter.

Check for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.

All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.

Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with a new ones if necessary.

Gaskets, seals, O-rings and lock nuts should be replaced any time when the transfer is disassembled.

In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, use it.

Observe the specified torque when assembling.

Clean and flush the parts sufficiently and blow-dry them.

Be careful not to damage sliding surfaces and mating surfaces.

Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transfer.
Wiring Diagrams and Trouble DiagnosisEDS001V8

GI-14, "How to Read Wiring Diagrams".

PG-2, "POWER SUPPLY ROUTING".
When performing trouble diagnosis, refer to the following:
