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 transmission
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.

2. Stop engine, and remove drain plug to drain transfer oil.
3. Apply sealant to drain plug. Install drain plug on transfer and
tighten to the specified torque. Refer to TF-57, "
COMPO-
NENTS" .
FILLING
1. Remove filler plug and add gear oil until oil level reaches the
specified limit near filler plug mounting hole.
CAUTION:
Carefully fill the oil. (Fill up for approx. 3 minutes)
2. Leave the vehicle for 3 minutes, and check the oil level again.
3. Apply recommended sealant to filler plug. Install filler plug on
transfer and tighten to the specified torque. Refer to TF-57, "
COMPONENTS" .
InspectionEDS001W3
OIL LEAKAGE AND OIL LEVEL
1. Check oil level from filler plug mounting hole as shown in the fig-
ure.
CAUTION:
Do not start engine while checking oil level.
2. Before installing filler plug, apply sealant. Install filler plug on
transfer and tighten to the specified torque. Refer to TF-57,

Drive Gear Assembly" .
8. Install the adapter case. Refer to TF-70, "
Adapter Case" .
9. Install the pinion sleeve assembly. Refer to TF-72, "
Pinion Sleeve Assembly" .
10. Check backlash, preload torque, tooth contact, and companion flange runout. Refer to TF-58, "
ASSEM-
BLY INSPECTION" .
CAUTION:
Measure the total preload torque without the oil seal.
Drive Gear Assembly
1. Using a drift, drive the gear ring oil seal into the gear ring.
CAUTION:

Do not reuse the oil seal.

Apply multi-purpose grease onto oil seal lips, and gear
oil onto the circumference of the oil seal.
