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

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, "
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.
c. Remove control valve assembly fitting bolts A , B and C .

INSPECTION
Oil Pump Housing, Oil Pump Cover, Inner Gear and Outer Gear
Check for wear or damage. Replace if necessary.
Side Clearances

Measure side clearance of inner gear and outer gear in at least
four places around each outside edge. Clearances measured
values should be within the specified clearance.

If clearance is less than standard, select inner gear and outer
gear as a set so that clearance is within specifications. Refer to
“Parts Information” for the inner gear and outer gear selection.

If clearance is more than standard, replace whole oil pump
assembly except oil pump cover.

Measure clearance between outer gear and oil pump housing.

If not within allowable limit, replace whole oil pump assembly
except oil pump cover.
Seal Ring Clearance

Measure clearance between seal ring and ring groove.

If not within allowable limit, replace oil pump cover assembly.Standard clearance: Refer to AT- 3 8 2 , "
