ASSEMBLY
1. Install oil pump housing oil seal on oil pump housing.
CAUTION:
Do not reuse oil pump housing oil seal.

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).
