(2): N-D accumulator piston

Inspect the sliding surfaces of manual valve and valve body, and
replace if damaged or dented.

Inspect each return spring, and replace if damaged, deformed or
worn. Refer to AT-380, "
Accumulator" for free length (L1 ) and
length (L
2 ).
(1): Return spring (Servo release accumulator)
(2): Return spring (N-D accumulator)
CAUTION:
Do not remove spring retainer (3).
Installation
Installation is in the reverse order of removal.
CAUTION:

Completely remove all moisture, oil and old gasket from the oil pan gasket mounting surface of
transaxle case and oil pan.

Do not reuse O-rings, lip seals, oil pan gasket and oil pan bolts.

Apply ATF to manual valve, O-rings, lip seals and sliding surfaces of the transaxle case.
NOTE:

Set manual shaft in “N” position, then align manual plate (1) with
groove in manual valve (2).

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

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

NOTE:

Drive each differential side oil seal evenly using a drift (SST and
commercial service tool) so that differential side oil seal pro-
trudes by the dimension “C” or “D” respectively.
(1): LH differential side oil seal
(2): RH differential side oil seal
(A): Transaxle case side
(B): Converter housing side
Unit: mm (in)

Differential side oil seal pulling direction is used as the refer-
ence.
Drift to be used:

After installing differential side oil seal, check A/T fluid leakage and A/T fluid level. Refer to AT- 1 6 , "Check-
ing A/T Fluid" .

CAUTION:

When replacing an engine or transmission you must make sure any dowels are installed correctly
during re-assembly.

Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.

Do not reuse O-rings and copper washers. Refer to AT- 2 5 3 , "COMPONENTS" .

When turning crankshaft, turn it clockwise as viewed from the front of the engine.

When tightening the bolts for the torque converter while securing the crankshaft pulley bolt, be
sure to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-37, "
TIMING
CHAIN" .

After converter is installed to drive plate, rotate crankshaft several turns to check that transaxle
rotates freely without binding.

When installing the torque converter to the transaxle measure
distance A.

Check the fitting of the dowel pins when installing the transaxle
assembly and the engine assembly.
: Dowel pin (2)

When installing the transaxle to the engine, align the matching mark on the drive plate with the matching
mark on the torque converter.

When securing the transaxle to the engine, attach the bolts in
accordance with the following standard.
(A): A/T to engine
(B): Engine to A/TDimension A: 14.4 mm (0.567 in) or more

Align the positions for the bolts on drive plate with those of the
torque converter, and temporarily tighten bolts. Then, tighten
bolts to the specified torque.

After completing installation, check for A/T fluid leakage, A/T
fluid level and A/T positions. Refer to AT-16, "
Checking A/T
Fluid" and AT-234, "Checking of A/T Position" . Converter nuts : 51 N·m (5.2 kg-m, 38 ft-lb)

11. Remove oil pan fitting bolts.
12. Remove oil pan and oil pan gasket.
13. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.

If frictional material is detected, replace radiator after
repair of A/T. Refer to CO-11, "
RADIATOR" .
14. Remove magnets from oil pan.
15. Remove control valve assembly according to the following procedures.
a. Remove snap ring (1) from terminal body (2).
CAUTION:
Do not expand snap ring (1) excessively.
b. Push terminal body (2) into transaxle case.
