• Inspect each return spring, and replace if damaged, deformed or
worn. Refer to AT-343, "
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 tran-
saxle 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 MA-22, "
Checking A/T Fluid".

TRANSAXLE ASSEMBLY
• 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 "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
.
• 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 dis-
tance 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 MA-22, "
Checking A/T Fluid" and
AT-207, "
Checking of A/T Position". Converter nuts : 51 N·m (5.2 kg-m, 38 ft-lb)

9. Set manual shaft (1) in “P” position.
10. Remove PNP switch (2) from transaxle case.
: Bolt (3)
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
.
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.
c. Remove control valve assembly fitting bolts A, B and C.
Bolt length, number and location:
d. Remove control valve assembly from transaxle case.
CAUTION:
Be careful not to drop manual valve.
