ASSEMBLY
1. Install oil pump housing oil seal on oil pump housing.
CAUTION:

Do not reuse oil pump housing oil seal.

Apply ATF to outer surface of oil pump housing oil seal.
2. Install inner gear and outer gear on oil pump housing.
CAUTION:
Be careful with the direction of inner gear.
3. Install oil pump cover on oil pump housing.
a. Wrap masking tape around splines of oil pump cover assembly
to protect seal. Position oil pump cover assembly on oil pump
housing assembly, then remove masking tape.
b. Tighten oil pump cover fitting bolts in the order as shown in the
figure, and then tighten them to the specified torque in the same
order. Refer to AT-289, "
COMPONENTS" .
4. Install seal rings (1) to oil pump assembly (2) carefully after
packing ring groove with petroleum jelly.
CAUTION:
Do not spread gap of seal rings (1) excessively while install-
ing. The seal rings (1) may be deformed.

3. Remove O-rings from solenoid valves and terminal body.
4. Place control valve upper body face down, and remove bolts
(B), reamer bolt (F) and nut.
CAUTION:
Remove bolts with control valve upper body facing down,
because control valve upper body and control valve inter
body may come off and steel ball may fall and be lost.
5. Remove control valve lower body (1) from control valve inter
body (2).
(3): Control valve upper body
6. Turn over control valve lower body (1).
7. Remove bolts (E), support plates (2) and separating plate (3)
from control valve lower body (1).
8. Remove check balls (1), line pressure relief valve springs (2)
and torque converter pressure holding spring (3) from control
valve lower body (4).
CAUTION:
Be careful not to lose check balls (1), line pressure relief
valve springs (2) and torque converter pressure holding
spring (3).
